Camera Basics

Introduction

A camera operator on a live show is trusted with the only thing the audience at home, on the stream or at the back of the room will actually see. Everything else on the show — the sound, the lighting, the set, the presenter's months of preparation — reaches them through somebody's framing and somebody's focus.

That is a lot of trust to hand a person with a camera, and the operators who keep being booked have earned it with habits more than talent: they arrive knowing what the show is, they set their camera up the same careful way every time, they speak on comms only when it helps, and they leave the room better than they found it.

What this book covers

How a camera makes a picture and how it connects to the system; exposure, colour and the light you are given; lenses and focus; composition and movement; supports, pedestals and handheld work; preparing for a shoot; working a live multi-camera show; and recording, care of the equipment and the wrap. It was measured against the standard texts, working studio camera courses and the national units for camera operation, so that nothing a camera operator is taught elsewhere is missing here.

How to Use This Book

Each chapter follows the same shape, and the shape matters more than it might look. You read the ideas, then you see them play out in a real situation, then you get the procedure, then you are shown what goes wrong and how to recognise it early. Reading only the parts that look new is the fastest way to arrive on a job holding half of something.

1. Read the chapter body first. This is the understanding layer, and it is written to be read straight through.
2. Read On the job. The same material as a real situation on a real show, which is where it stops being abstract.
3. Work through How to do it. These are procedures you can follow on a job this week.
4. Study What goes wrong. Experienced technicians are not people who never make mistakes; they are people who recognise mistakes early.
5. Do the exercise before reading the answer key. Recognition feels like learning and is not.
6. Take the checklist with you. Photograph it on your phone. Use it until you no longer need it.

Keep a notebook

One habit is worth starting today, before the first chapter: keep a small notebook and write the technical details in it as you meet them. Camera work runs on settings — the show's frame rate and shutter, where zebras are set, the white balance for this room, the focus mark for the lectern, which channel the director is on, how long a battery really lasts on this camera.

Write it by hand rather than photographing this page. Copying a number puts it on paper; rewriting it in your own words is what puts it in your head, and deciding how to word it is most of the understanding.

Then use it twice. Read a few pages on the way to a job, which takes five minutes and turns things you half-know into things you know. And carry it on the job, because the setting you cannot remember is always the one somebody is waiting for.

A note on the words

Camera vocabulary changes between broadcast, film and live events, and between manufacturers, and it is worth expecting that. Matching cameras is shading to one crew and painting to another, and the person who does it may be called a vision engineer, a shader or racks. A pedestal is a ped. The return button may be RET or marked with the manufacturer's own word. And ISO means two different things in the same truck: the sensitivity of a sensor, and an isolated recording of one camera.

None of that is worth arguing about. What matters is that you can say what a control or a job does, because a person who can describe the function will be understood anywhere, and a person who only knows one crew's word for it will not.

A note on safety

Camera work looks safe and carries real hazards. System cameras with large lenses are heavy and are lifted onto heads at shoulder height; jibs swing a counterweight at head height; camera risers are working platforms with edges; and camera cable runs across floors that audiences walk in the dark. Stage lasers can injure eyes and burn a camera's sensor in an instant, and cameras run on mains power and large lithium batteries.

Nothing in this book authorises you to do work that has its own training — driving a jib, operating a lift, working at height, electrical work. Knowing why a thing is done is not the same as being trained to do it. If you are ever unsure whether something is yours to touch, the answer is to ask.

Before You Begin

How a Camera Makes an Image

Light in, image out. Understanding the path makes every setting meaningful.

Lens, sensor, and signal

A camera turns light into a video signal. Light from the scene passes through the lens, which focuses it onto the sensor — an electronic surface that converts light into an electrical signal. The camera then processes that signal and outputs it as video (over SDI or HDMI) to a switcher, recorder, or display. The camera is the source at the head of the video chain you learned in Video Basics, and everything downstream depends on the image it captures.

Because the camera is the source, its image sets the ceiling on quality. No switcher or processor can add detail or fix exposure the camera never captured well. This is why operating a camera well — getting exposure, focus, and framing right at the moment of capture — is a craft worth real attention.

The sensor and light

The sensor needs the right amount of light to make a good image. Too little and the picture is dark and noisy; too much and the highlights blow out to featureless white. Most of the operator's technical work is managing how much light reaches the sensor and how the sensor responds to it — which is the subject of exposure, the next module. Sensor size and quality also affect the look, but the fundamental job is always to deliver the right light, in focus, framed well.

Cameras range from broadcast cameras built for live multi-camera shows, to cinema cameras for film, to compact cameras and even phones. They differ enormously in features and cost, but they all share this same core: light through a lens onto a sensor, converted to a signal. Learn the fundamentals on any camera and they transfer to all of them.

Sensor size, and the thing it actually changes

Sensor size is talked about as though it were a quality rating. It is not. A larger sensor is not sharper, and on a live show it is often harder to work with.

What a larger sensor changes is depth of field. For the same framing, a bigger sensor gives a shallower band of sharpness — the look people mean when they say cinematic, and the reason a cinema camera makes a background melt away. On a scripted set with a focus puller, that is an asset. On a corporate stage where a presenter wanders two metres in either direction and you are also listening to a director, it is a liability, because your margin for error shrinks with it.

This is why broadcast cameras built for live multi-camera work have smaller sensors than cinema cameras, and it is a choice rather than a compromise. More depth of field means a shot that stays sharp while you concentrate on framing. A camera that makes it easy to hold focus is worth more on a live show than one that makes a prettier still.

Frame rate, shutter, and why motion looks wrong

A video camera takes a run of still frames. How many per second is the frame rate, and it is not a free choice — it is set by the show, the region and what the pictures are for, and every camera on the job must agree.

Shutter is how long each of those frames is exposed. The two are related by a rule of thumb inherited from film: set the shutter to about double the frame rate, and motion looks natural. At 25 frames per second that is 1/50th of a second; at 30, about 1/60th.

Depart from it and motion changes character. A much faster shutter freezes each frame individually, so a pan becomes a series of sharp stills and the movement judders — it looks like the footage in a certain kind of war film, and on a corporate keynote it looks like a fault. A much slower shutter smears movement, which hides detail and looks soft.

There is one more reason not to treat shutter as a brightness control: under some lighting, the wrong shutter speed makes the picture flicker or roll. Lights that pulse with the mains supply, and LED fixtures that dim by switching on and off very fast, both beat against the shutter. If a picture flickers and the lighting is not at fault, shutter is the first thing to check.

The cameras you will be handed

The fundamentals are the same on every camera, but the camera you are handed decides what the day is like. Five kinds turn up on live and event work, and each one puts the controls in a different place and hands a different share of the job to somebody else.

A system camera, sometimes called a studio or broadcast camera, is the one on a pedestal or a big tripod with a large lens and a viewfinder like a small monitor. It does not stand alone. A single cable runs from it to a camera control unit in the truck or the rack, and down that cable come power, the picture, the director's voice and your tally. On a system camera you usually do not own exposure or colour at all; somebody in the truck does, and your job is framing and focus.

A camcorder, or ENG camera after the electronic news gathering it was built for, sits on the shoulder or a tripod and does everything itself: its own battery, its own recording, its own exposure. On a small show it may also feed the switcher. Every control is yours, which is freedom and responsibility in the same box.

A PTZ camera, for pan, tilt and zoom, is a small robotic camera bolted to a wall, a truss or a stand, driven from a joystick somewhere else. They are everywhere in corporate rooms, churches and hybrid meetings. Nobody stands behind it, so nobody notices it has drifted, which is why what it does automatically matters so much.

Cinema-style and mirrorless cameras have large sensors and interchangeable lenses and make beautiful pictures. They turn up on events that want a filmic look, often handheld or on a gimbal. Expect shallow depth of field, small screens, menus rather than buttons, and batteries that do not last a keynote.

And increasingly there is a camera nobody operates: a locked-off wide on the back wall, a phone on a stand, a laptop webcam in a hybrid meeting. They still count as cameras on the show, and they still need someone to have set them properly before walking away.

The first thing to ask when you are handed any of them is who owns what. Who controls the iris, who sets colour, who presses record, and where the picture goes. On a system camera the answer is mostly "not you"; on a camcorder it is all you. Assuming the wrong answer is how two people adjust the same thing in opposite directions.

Frame rates you will actually meet

Frame rate is a property of the SHOW, not of your camera. Every camera, the switcher and the recorder must run the same one.

The cameras, side by side

What each kind is, where you meet it, and who normally owns the picture.

On the job

You are handed a camera an hour before doors on a two-camera corporate session. The other operator has been there since the truck arrived and her camera is already built.

The first question is not about your camera. It is what frame rate the show is running, and the answer comes from the person at the switcher, not from you. If her camera is on 25p and yours arrives on 59.94p, the switcher will either refuse your picture or accept it and do something ugly to it, and the first anybody knows will be when they cut to you.

So you ask, you set it, and then you ask the second question: is anyone shading. If yes, you leave iris alone for the rest of the day. If no, you and she white balance off the same card under the same light before either of you frames anything.

Three minutes of asking, at the only point in the day when the answers are cheap.

The Camera in the System

A camera on a live show is never on its own. It is one end of a cable that carries its picture away and brings back everything the operator needs to do the job: power, the director's voice, the red light that says you are live, and a picture of what the audience is seeing.

This chapter is about that cable and what travels along it. It is the part of camera work that is invisible when it works, and the part that ends a show when it does not.

The camera control unit, and the cable that feeds it

A system camera is really two boxes. One is the camera head you stand behind. The other is the camera control unit, or CCU, which lives in the truck, the rack or the control room, and the two are joined by a single cable.

That cable is doing a lot. It carries the picture from the camera to the CCU, where it becomes an ordinary video signal for the switcher. It carries power the other way, so the camera needs no battery. It carries the intercom, so your headset plugs into the camera rather than into a separate belt pack. It carries tally, so the switcher can light your red light. It carries a return picture back to your viewfinder. And it carries remote control, so somebody at a small panel in the truck can adjust your iris and colour without touching the camera.

Two kinds of cable do this job. Triax is a thick copper cable with a centre conductor and two shields, and it has been the workhorse for decades because it is tough, repairable in the field and happy over hundreds of metres. Hybrid fiber, usually called SMPTE fiber after the standard that defines it, carries the signals as light over two glass fibers and carries power over copper conductors alongside them, in one jacket. It reaches further, carries the higher resolutions more comfortably, and has one weakness that matters more than all its strengths: its connectors hate dirt.

Smaller shows skip the CCU entirely. A camcorder or PTZ camera sends its picture over SDI coaxial cable, or over a network, straight to the switcher, and power, comms and tally each arrive some other way, or not at all. Knowing which kind of system you are on tells you which of those things you have to arrange yourself.

Fiber connectors, and the speck of dust that ends a camera

A hybrid fiber connector passes light across a gap between two glass faces thinner than a hair. A speck of dust on either face blocks enough of that light to make the picture break up, freeze, or disappear, and a scratch made by grinding dust into the face is permanent.

So fiber has rules that copper never needed. The dust cap stays on every connector until the moment it is mated, and goes back on the moment it is unplugged, including the caps on the cable you are coiling at the end of the night. The cap goes in a pocket, never on the floor. A connector that has been left uncapped gets cleaned with the proper cleaning tool before it is plugged in, never with a breath and a sleeve.

And fiber has a bend radius. Kink it, crush it under a road case wheel, or pull it tight round a sharp corner and the glass cracks inside an undamaged jacket. The camera will work intermittently, which is worse than not working at all.

When a fiber camera shows an optical fault, the first two things to try are the cheapest: clean both ends of every connection in the run, and look for somewhere the cable is being bent or crushed. Most fiber faults on a show are one of those two.

Genlock, and why every camera has to keep the same time

A video picture is a stream of frames, and each camera starts every frame at a moment of its own choosing. Left alone, four cameras running at the same frame rate still start their frames at four different instants.

A switcher cutting between them has a problem. If camera two's frame started a third of a frame after camera one's, the cut lands in the middle of something. On older systems the picture rolls or tears at the cut. On modern switchers, a frame synchroniser on each input quietly delays the late camera to line it up, which works, but costs a frame of delay and now and then drops or repeats a frame.

The proper answer is genlock. A single reference signal, usually generated by a sync pulse generator in the rack, is sent to every camera, every CCU and every other source, and each one locks the start of its frames to it. Now every frame on the show begins at the same instant, and a cut is just a change of which picture is passed on.

On a system camera the CCU handles genlock and you will never see it. On camcorders and PTZ cameras there is often a genlock input on the back, and whether it needs a cable is a question for the engineer. The symptom of a camera that should be locked and is not is a brief glitch or roll on every cut to it, or audio slowly drifting out of step with the picture on a long record. Neither is a fault in the camera; both are a missing cable.

Return video, and watching the programme as well as your shot

Your viewfinder shows your own picture. It can also show somebody else's.

On a system camera, a button on the camera or the lens handle, usually marked RET, swaps the viewfinder to a return feed sent back down the camera cable. What that feed is depends on the show: most often it is the programme, what is actually going out, and sometimes it is another camera, a teleprompter feed or a preview of the next shot.

An operator who uses it well does three things with it. They check what the other cameras are giving the director, so they offer something different rather than a third close-up of the same person. They see the graphics and the lower thirds that will sit on top of their picture, and frame around them. And when the director is cutting fast and the comms are busy, they can see whether they are on air even before they look at the tally.

On a show without return video, the multiview monitor in the room or a small programme monitor near your position does the same job. What you should not use is the big screen in the room. IMAG, image magnification, runs through a processor and is often a fraction of a second behind, and an operator who frames by watching it ends up chasing a picture that has already moved.

The viewfinder, and the settings that lie to nobody but you

The viewfinder is a monitor, and like every monitor it can be adjusted. The important thing to understand is that nothing you do to it changes the picture going out. Brightness, contrast and peaking on the viewfinder affect only what you see.

That makes it a tool rather than a window. Peaking draws a coloured or white outline on the sharpest edges in the frame, so you can see focus land even on a small screen; set it high enough to see and low enough not to hide the picture. Many cameras also have a magnification button that enlarges the centre of the frame for a moment so you can check critical focus.

Contrast and brightness should be set so that the viewfinder shows detail in both the dark and the bright parts of the picture, and they should be set in the light you will operate in. A viewfinder turned up bright in a dark arena will make every picture look overexposed, and one turned down in a sunlit room will make every picture look dark. This is exactly why exposure is judged with zebras or a waveform, not with the viewfinder's brightness.

Markers are the other thing the viewfinder can draw: a centre cross, a box showing the safe area for graphics, and the edges of other aspect ratios if the picture will also be shown somewhere cropped. Turn on the ones that apply to the show and leave off the rest, because a viewfinder full of lines is its own distraction.

Sound on the camera

Almost every camera can record sound and send it with the picture. On a live multi-camera show it usually is not where the programme sound comes from — that comes from the audio desk — but the sound on the camera still does useful jobs, and there are times it is the only sound there is.

A camera's built-in microphone records the room: what the presenter sounds like from where the camera is, the applause, the ambience. That scratch sound is how an editor lines up an isolated camera recording with everything else later, and it is worth leaving on for that reason alone.

Most professional cameras also have one or two XLR inputs on the body. A microphone can go straight in, with the camera supplying phantom power if it needs it, or a line feed can come in from the audio desk. A line feed and a microphone input are very different levels, and plugging one into the other either produces nothing you can hear or distortion you cannot remove, so the input switch has to match what is plugged in.

When the camera is recording for itself — a roving handheld getting interviews, a camera recording the show as a backup — sound becomes your responsibility. Monitor it on headphones, not by trusting the meter alone. Keep the level peaking comfortably below the top. And place the microphone for the voice rather than for the camera: a microphone on the camera is at the wrong distance for almost everything except the camera operator's own breathing.

What travels down the camera cable

On a system camera, one cable carries all of this. On a small show with camcorders or PTZ cameras, each line of this table is something somebody has to arrange separately.

Camera cables, and how far each will go

Typical working distances, not guarantees. Cable quality, connectors and the camera's power draw all move these numbers.

How to do it

1. Before connecting anything, check that the caps are off only the connectors you are about to mate, and that a fiber connector is clean. Mate the camera cable at the camera and at the wall box or CCU.
2. Ask the engineer or vision operator to power the camera from the CCU. Do not power a triax or fiber camera by any other means.
3. Put on the headset, plug it into the camera and call in on comms with your camera number. Confirm you can hear, and that you are heard.
4. Check your picture is arriving by asking the person at the switcher or the vision engineer, not by looking at your viewfinder.
5. Press the return button and confirm you can see the return feed, and what it is.
6. Ask for a tally test and confirm your tally lights on the camera and in the viewfinder when your camera is selected.
7. Set viewfinder brightness, contrast and peaking in the lighting you will operate in, and turn on the markers the show needs.
8. Confirm with the engineer who controls iris, white balance and gain, and leave those controls alone if they are not yours.

What goes wrong

Exposure

Exposure is the balance of light that makes an image look right. Three controls set it.

The exposure triangle

Exposure is how bright or dark the image is, and it is controlled by three settings that work together — the exposure triangle. Aperture is how wide the lens opens to let light in (it also affects how much is in focus front-to-back). Shutter controls how long each frame is exposed to light (and affects how motion looks). ISO or gain is the sensor's sensitivity to light (raising it brightens the image but adds noise). Together these three set how much light forms the image.

They are a balance, like the triple constraint in project management: change one and you compensate with another. Open the aperture and you may need a faster shutter; raise ISO and you accept more noise. A camera operator learns to juggle the three to get correct brightness while controlling the side effects — depth of focus, motion look, and noise.

Getting exposure right

Correct exposure keeps detail in both the bright and dark parts of the image — highlights that are not blown out to white, shadows that are not crushed to black. Operators judge exposure by eye on a good monitor and with tools the camera provides (such as indicators that warn when highlights are clipping). In live and broadcast work there is often a target the whole multi-camera setup must match, so every camera looks consistent when the switcher cuts between them.

A special concern on camera is light and colour agreement — this is where the colour temperature you met in Lighting Basics returns. Cameras must be set to the right white balance for the lighting, or whites and skin tones look wrong. Correct exposure plus correct white balance is what makes an image look natural rather than too dark, blown out, or oddly tinted.

Reading exposure with the tools, not with your eyes

A monitor lies. It lies in a dark truck where everything looks bright, it lies in a sunlit ballroom where everything looks dark, and it lies whenever somebody has turned its brightness up to see the menus. An operator who exposes by eye is exposing for the monitor, not for the picture, and the two agree only by accident.

Every professional camera carries tools that do not lie, because they measure the signal rather than display it. Three are worth knowing, and any one of them beats a good eye.

Zebras are diagonal stripes the camera draws over any part of the image brighter than a level you set. Two settings cover most work. At around seventy percent, the stripes appear over correctly exposed light skin, so you expose a face by opening the iris until the stripes just appear on the cheek and forehead. At ninety-five or a hundred percent, the stripes appear only where the picture is about to clip, so they become a warning rather than a target: stripes on the presenter's white shirt mean the shirt is turning into a shape with no texture in it.

A waveform monitor draws the brightness of the picture as a graph, left to right across the frame, with black at the bottom and peak white at the top. It is the tool a vision engineer uses, and it tells you at a glance whether the whole image sits in the usable range or whether the top of it is flattened against the ceiling. Faces normally sit somewhere around sixty to seventy on that scale.

False colour replaces the picture with a map of exposure values: a specific colour for clipping, another for correct skin, another for the shadows. It is the fastest of the three to read and the ugliest to look at, which is why it is usually toggled on, checked, and toggled off again.

Use whichever the camera has. The point is not the tool, it is that you stop guessing.

What clipping actually destroys, and why you protect the top

A dark picture is a problem. A clipped picture is a loss.

When a part of the image is brighter than the sensor can record, it does not become very bright — it becomes nothing. Every pixel in that region reads the same maximum value, so there is no difference between one part of the window and another, and no adjustment afterwards can invent the difference back. The information was never captured. A face that clips loses the modelling that makes it look like a face and becomes a flat white shape with eyes.

Shadows behave differently, which is why the two are not symmetrical. A dark picture that was recorded still contains information; lifting it brings up noise along with the detail, which is ugly, but it is recoverable. A crushed shadow — one that has hit the bottom — is gone in the same way a clipped highlight is gone.

The working consequence is that an operator protects the top of the picture and accepts a slightly darker image, rather than the other way round. When a presenter stands in front of a bright LED wall or a window, you expose for the face and let the background go bright, or you ask for the background to come down. What you do not do is split the difference and clip both.

Matching cameras, and who is allowed to touch what

On a single-camera shoot the picture only has to look right. On a multi-camera show it has to look right AND look like the other cameras, because the audience sees the difference at every cut. One camera a little warmer than the rest is invisible on its own monitor and glaring on the screen.

Matching cameras is a real job with a real name. To paint the cameras, or to shade them, is to make them agree; matched cameras are the result. The person doing it is a vision engineer, also called a shader or racks, and they work from a remote control panel — one small desk per camera — rather than from the camera itself. From there they control iris, black level, white balance and the finer controls that shape how the camera handles highlights and detail. Their whole job is to make four or six cameras look like one.

This changes what the operator does. If a show is being shaded, the operator does not set iris. Touching it fights the person whose job it is, and the two of you will chase each other all afternoon. Ask at the start of the day whether the cameras are being shaded and who has iris, and then leave it alone. What remains yours is framing, focus and movement — which is most of the craft anyway.

On smaller shows there is no shader, and the operator does their own exposure and white balance. Then matching becomes a conversation before doors: everyone white balances off the same card under the same light, and everyone agrees where the faces should sit.

Neutral density, and the control most people forget

There is a fourth exposure control, and on any bright stage it is the one you reach for first.

Neutral density is grey glass. It cuts the light reaching the sensor without changing its colour, and it exists because the other three controls all have side effects you may not want. If a stage is bright enough that correct exposure needs the iris closed right down, you have been handed a deep depth of field whether you wanted one or not, and nothing you do with shutter or gain gets it back. Put ND in and you can open the iris again and choose your depth of field on purpose.

Broadcast cameras carry ND in a wheel behind the lens, usually in two or three strengths, switched with a knob on the side of the camera. Smaller cameras often have it built in as a menu setting or need it screwed on the front.

Two things go wrong with it. The first is forgetting it is in: a camera that was outside in daylight comes inside and the picture is inexplicably dark, and the operator winds gain up to compensate rather than clearing the filter. The second is changing it live — the picture jumps a full stop or more as the wheel passes between positions, so ND is set before you are on air, not during.

Automatic controls, and the moments they betray you

Every camera will expose, focus and colour-balance itself if you let it. The automatics are good, and on a phone they are the whole point. On a live show they are a set of decisions made by something that cannot hear the director, does not know what the shot is for and does not care what happens at the cut.

Auto iris measures the average brightness of the frame and opens or closes the lens to bring it to a middle value. That works in an evenly lit scene. It fails in exactly the situations a stage creates. A presenter in a pool of light against a black set is mostly surrounded by dark, so auto iris opens up to brighten the average and burns out the face. The same presenter walking in front of an LED wall makes the frame suddenly bright, so the iris closes and the face goes dark. A follow spot crossing the frame makes the iris pump up and down on air, which the audience sees as the whole picture breathing.

Auto gain, sometimes called AGC, does the same thing with amplification. As the room darkens it quietly adds gain, and the picture gets noisier without anybody deciding it should. Auto shutter does it with shutter speed, and changes how motion looks halfway through a shot.

Auto white balance, or auto tracking white, keeps re-deciding what white is. When a lighting state changes from cool to warm, it follows, and the camera drifts away from the cameras that were set by hand. On a multi-camera show that is a mismatch at every cut.

None of this makes automatics wrong. A momentary auto iris button, pressed once to take a reading and then released back to manual, is a fast way to get close. A PTZ camera on a static wide in a room with windows may genuinely be better on auto iris than on a setting nobody will ever touch again. The rule is not "never use auto". It is that you decide when the camera is allowed to decide, and on a live show with changing light the answer is almost always: once, before the shot, and then locked.

Setting white balance, and the light that defeats it

White balance tells the camera what colour white is under the light it is actually in. Get it right and skin looks like skin. Get it wrong and every face goes orange or blue.

Most cameras offer three ways. Presets for tungsten, around 3200K, and daylight, around 5600K, are quick and consistent, and they are how cameras from different manufacturers are brought close to each other. A one-push white balance, often labelled AWB and stored in memory A or B, measures a white card and sets the camera exactly for that light. Auto tracking white follows the light continuously, with the problems described above.

The one-push is the accurate one, and it has a procedure. The card goes where the subject will be, facing the camera, lit by the light the subject will be lit by. It fills most of the frame. Exposure is roughly correct, because a card that is clipped or very dark gives the camera nothing to measure. Then you push, wait for the confirmation, and look at a face.

Mixed light is where it gets hard. A presenter lit warm from the stage and cool from a window, or a face lit by stage fixtures standing in front of an LED wall set to daylight, is lit by two whites at once, and no single balance makes both look right. The working answer is to balance for the face, because the audience forgives a background that is a little warm or cool and does not forgive a face. When the difference is severe, the fix is not on the camera at all: it is a gel on the window or a colour change on the wall, and that is a conversation with the lighting or LED team.

Two things not to do. Do not balance off the LED wall, a white shirt under a coloured light, or a projection screen, because none of them is lit by the light on the face. And on a show with a vision engineer, do not push white balance at all without asking; you frame the card, they set the balance.

Filters beyond neutral density

A filter is a piece of glass placed in front of the lens or inside the camera to change the light before it reaches the sensor. Neutral density, covered earlier, is the one used every day. Several others turn up often enough that an operator should know what they do and what each one costs.

Many broadcast cameras have a second filter wheel beside the ND wheel for colour correction. Its positions shift the camera's colour towards daylight or tungsten before white balance does the rest, which keeps the balance working in a comfortable range and keeps noise down in the blue channel. If a camera that was fine indoors looks strangely blue outside even after a white balance, a colour correction wheel left in the wrong position is the first suspect.

A polarising filter cuts reflections. It removes glare from glass, from water and from shiny surfaces, lets you see through a window rather than at your own reflection in it, and deepens a blue sky. It is rotated to control the effect, and the effect changes as you pan, so a polariser that is perfect on a static shot can make a moving one change as it goes. It also costs light — typically well over a stop.

Diffusion filters soften highlights and skin and add a slight glow round bright lights. They are popular for a filmic look and flattering on faces. On a multi-camera show they are a trap: one camera with diffusion and three without is a visible change at every cut, so it is all cameras or none, and it is decided before the show rather than by one operator.

Protection and UV filters are clear glass screwed on to protect the front element. They are sensible on a handheld camera in a crowd. But every extra piece of glass adds two surfaces for light to bounce between, and a cheap filter costs sharpness and causes flare. A filter in front of an expensive lens should be at least as good as the lens.

Flare, the streaks and haze when a bright light points into the lens, is fought with a lens hood, a matte box or a flag rather than a filter. Stage lighting points at the audience, and the camera is in the audience, so a follow spot, a backlight or an audience blinder in your frame is normal on a live show. A hood that is fitted properly, and a camera position a metre to one side, prevent more flare than anything that screws on.

LED walls, flicker and moiré

An LED wall behind a presenter is now the most common background on a corporate stage, and cameras and LED walls interfere with each other in two distinct ways. Each has a different cause and a different cure, and knowing which one you are looking at saves a lot of turning knobs.

The first is flicker or rolling bands. An LED wall does not glow continuously; it switches its pixels very fast, at its refresh rate. If the camera's shutter samples that at an unlucky rate, the picture shows dark bars rolling through the wall or a steady pulse. The cure is shutter. Many cameras have a fine shutter adjustment, often called clear scan or flicker reduction, that lets you step the shutter speed in small increments until the bars stop. The LED technician can also help by raising the wall's refresh rate or locking the LED processor to the same reference as the cameras, and on a big show that is set up before anyone points a lens at it.

The second is moiré: a shimmering pattern of curved lines or coloured ripples across the wall. It is the grid of LED pixels interfering with the grid of pixels on the camera's sensor, and it appears when the wall is sharp and its pixels are close to the size of the sensor's pixels in the image. Shutter does nothing to it. The cures are geometry and focus: change the focal length or the distance so the pixel sizes stop lining up, change the angle to the wall, or let the wall fall slightly out of focus while the presenter stays sharp. A presenter standing well in front of the wall, with the camera focused on them, is the arrangement that avoids it.

The same interference appears on a presenter's finely striped shirt or a tweed jacket, where it is called strobing or patterning. The cure there is usually a word before the show about what not to wear.

Working with the light you are given

A camera operator on a live show rarely lights anything. The lighting designer lights the stage for the audience in the room and for the cameras at the same time, and the operator works with what that produces. What the operator can do is see what the light is doing to the picture, and say so to the right person.

The camera sees contrast more harshly than the eye. A face that looks fine to someone in the room can be badly lit on camera, because the camera cannot hold detail in both a bright background and a dim face at once. When a presenter is darker than what is behind them — a bright LED wall, a window, a backlight — you have to choose between exposing for the face and letting the background clip, or exposing for the background and making the face a silhouette. Expose for the face, and tell the director that the background is the problem.

Direction matters as much as amount. Light from high and steep puts the eyes in shadow, which looks tired on camera. Light only from behind rims the head beautifully and leaves the face dark. Light straight from the camera position flattens the face into a disc. The operator cannot move the lights, but they can see these things through the lens before the show and raise them, while the designer still has time to adjust.

Where the operator does have control is position and timing. Moving a camera a little to one side can take a backlight out of the lens or put more of the key light on the side of the face you see. Knowing the lighting cues — when the stage goes to a blackout, when a coloured wash comes in — means you are not surprised by an exposure change on air.

The route for all of this matters. On most shows an operator does not speak to the lighting desk directly; they tell the director or the vision engineer, who decides whether to ask. A camera op who shouts across the room at the lighting designer during a rehearsal is not solving a problem.

The f-stop scale, and what a stop is

A stop is a doubling or halving of light. It is the unit everything about exposure is counted in, and it applies to iris, shutter, gain and ND alike — which is what lets you trade one against another.

The same move in other controls

• Halving the shutter time — 1/50 to 1/100 — is one stop less light.
• Adding 6 dB of gain is one stop more light, and one stop more noise.
• Each ND position on a broadcast wheel is typically two stops.

Focus & Lenses

A perfectly exposed shot is useless if it is soft. Focus and lens choice shape the image.

Focus

Focus is making the subject sharp. The operator adjusts the lens so the intended subject is crisp, and the great challenge of live work is holding focus as the subject or camera moves. Depth of field — how much of the scene is sharp front-to-back — is affected by aperture and lens: a shallow depth of field (subject sharp, background blurred) is beautiful but unforgiving, because a subject that moves even slightly can drift out of focus.

Pulling focus — adjusting focus smoothly as distance changes — is a real skill, especially with shallow depth of field and moving subjects. On many live shoots operators use a deeper depth of field to keep subjects reliably sharp. The professional habit is to check focus constantly, often zooming in on a monitor to confirm critical sharpness, because soft focus is one of the few mistakes that cannot be fixed later.

Lenses and focal length

The lens shapes the shot before the sensor ever sees it. Focal length determines how wide or tight the view is: a wide lens (short focal length) takes in a broad scene and exaggerates depth; a telephoto lens (long focal length) magnifies a distant subject and compresses depth. A zoom lens covers a range of focal lengths, letting the operator reframe from wide to tight without moving — essential for live shows where a single operator covers many shot sizes.

Focal length is a creative and practical choice. Wide for establishing a whole stage; tight for a presenter's face from the back of the room. Understanding what each does lets the operator get the shot the director wants quickly. On a live multi-camera show, operators are often assigned roles — one stays wide, another gets close-ups — and the lens is the tool that delivers each.

Back focus, and the fault that looks like a broken lens

Here is a fault that has ended more than one operator's afternoon. You focus on a presenter while zoomed in tight. The shot is sharp. You zoom out to a wide, and the picture goes soft. You zoom back in and it is sharp again. The lens looks broken.

It is not broken. Its back focus is out.

Back focus, also called flange focal distance, is the distance between the back of the lens and the sensor. A zoom lens is built so that a subject held in focus at the telephoto end stays in focus all the way out to wide — but only if that distance is set correctly. When it is not, the focus drifts as you zoom, and because it drifts smoothly, it looks like bad focusing rather than a setting.

Setting it takes a minute, and the steps are under How to do it at the end of this chapter.

Set back focus on every camera during prep, and set it again if a lens is changed or the camera has had a hard journey. It is the cheapest insurance on the call.

Following focus on somebody who moves

Presenters walk. They step out from behind the lectern, move downstage to make a point, and drift back again, and the shot has to stay sharp through all of it. This is the most visible skill an operator has, because a soft shot is obvious to everybody in the room including people who know nothing about cameras.

How much margin you have is depth of field — the band of distance that is acceptably sharp at any moment. Three things set it, and all three are yours.

A wider iris gives less depth of field. A longer focal length — zoomed in — gives less. And the closer the subject is, the less there is. So the hardest shot to hold is a tight close-up on a nearby subject with the iris wide open, which is also the shot a director asks for most.

Riding the ring to keep a moving subject sharp is to follow focus, or to pull focus — the two phrases mean the same thing, and you will hear both. On a film set it is a whole job: a focus puller works a follow focus wheel and never looks through the camera. On a live show it is yours, and it happens while you are also framing and listening to the director.

The technique is anticipation rather than reaction. Chasing focus means you are always behind, and the correction itself is visible. Instead, watch where the person is going and get there first. If a presenter is walking toward you, focus slightly in front of them and let them walk into it.

On a zoom lens there is a trick worth knowing: focus at the telephoto end, then zoom out to your shot. Focusing is far more precise when zoomed in, and a correctly back-focused lens holds it as you widen. Do this before a move rather than during one.

And when all of it is going wrong, widen out. A wider shot has more depth of field and hides small errors, and a wide shot that is sharp is always better than a tight one that is not.

What focal length does to a face, and to a room

Focal length is usually explained as how much you can see — short is wide, long is tight. That is true and it is the less interesting half.

The more useful half is what it does to depth. A wide lens close to somebody exaggerates distance: the nose is noticeably nearer the camera than the ears, so it comes out bigger, and the face looks stretched. A long lens from further back compresses distance: features flatten, the background appears to sit right behind the subject, and people generally look better.

This is why a flattering shot of a person is taken from further away with a longer lens, and why a wide shot pushed close to somebody's face is unkind. It is also why a long lens makes a half-empty room look full — the rows compress into each other — and a wide lens makes the same room look sparse. A director asking for a shot that makes the audience look bigger is asking for a long lens from the back, not a wide one from the front.

The trade-off is that longer lenses magnify everything, including your own movement. At the long end of a zoom, a hand on the camera is visible in the frame, and a shot that is rock steady at wide becomes unusable handheld.

The lenses you will meet

Almost every lens on a live show is a zoom, because a single operator has to deliver a wide, a mid and a close-up from the same position without changing anything. But zooms come in very different sizes, and the size decides how the camera handles.

A portable or ENG lens is the zoom on a camcorder or a shoulder-mounted broadcast camera. It has a handgrip with a zoom rocker under your fingers, a focus ring you turn by hand at the front, and switches for the iris and zoom motors. It typically zooms somewhere between fourteen and twenty-five times.

A box lens is the big square lens on a sports or arena camera, sitting in a cradle on the pedestal or tripod with the camera body behind it. It can zoom fifty, eighty or more than a hundred times, so an operator at the back of an arena can fill the frame with a single face on stage. It is never touched by hand; it is driven by a zoom control on one pan bar and a focus control on the other.

A prime lens has one focal length and no zoom. Primes are sharper, faster and smaller for their quality, and they belong on cinema-style cameras where somebody has decided the look matters more than flexibility. On a live show a prime means the operator changes shot size by moving, which is only practical on a handheld or a gimbal.

Cinema zooms sit between the two: large, heavy, very sharp, with gears for a focus puller and a zoom motor. They turn up when an event wants a filmic look on a camera that also has to cover a stage.

Zoom ratio, extenders, and the closest a lens will focus

A zoom lens is described by its range, and the range is written as two focal lengths or as a ratio. A lens that goes from 8 mm to 160 mm is a twenty-times zoom, because the long end is twenty times the short end. The ratio tells you how much tighter you can get without moving; the short end tells you how wide you can go, which on a cramped stage matters just as much.

Many broadcast lenses have a built-in extender, a lever or button that drops an extra group of glass into the light path and doubles every focal length at once. It is a way to get closer when the zoom has run out. It has a price: doubling the focal length costs two stops of light, so a picture that was comfortable at f/2.8 now needs f/5.6 worth of light it does not have. Extenders also soften the picture a little. Use one when the shot needs it, remember it is in, and take it out when you go wide again.

Many zooms also lose some light at the long end, known as ramping. As you zoom in, the lens can no longer open as wide, and the picture darkens slightly. Zebras that were right on the wide can be under on the tight, which is one more reason to check exposure at the size you will actually use.

Every lens has a minimum object distance: the closest a subject can be and still be brought into focus. On a long broadcast zoom it can be a metre or more. A presenter who walks right up to a camera becomes impossible to focus however hard you turn the control, and the answer is to zoom out and step back, not to keep turning. Some lenses have a macro setting that focuses much closer at the wide end; it is useful for product shots and useless the moment you need to zoom.

The controls on a broadcast lens

On a pedestal or tripod with a studio lens, your hands never touch the glass. Two controls on the pan bars drive it.

The zoom demand sits on one pan bar, usually the right. It is a thumb rocker or a twist grip, and it is proportional: push a little and the zoom creeps, push hard and it races. Almost all good zooming on air happens at the slow end of that range, so an operator spends time before the show learning exactly how little pressure starts the zoom moving. A speed setting on the demand limits how fast it will go.

The focus demand sits on the other pan bar, usually the left. It is a wheel or capstan turned by hand, and like a focus ring it has a direction. Some operators want clockwise to bring focus closer and others want the opposite, and many demands have a switch to reverse it. Set it the way you expect before the show, because a focus control that goes the wrong way sends a shot soft at exactly the moment you are trying to sharpen it.

Many lens systems also have a shot box or preset buttons that store a zoom position and recall it at a set speed. They make repeatable shots precise — the same tight on the lectern every time the speaker changes — and they are only safe to recall off air, because a preset moves at its own speed rather than yours.

On an ENG lens the same controls are on the lens itself: a zoom rocker under the fingers of the right hand, the focus ring at the front, an iris switch between auto and manual, and a zoom servo switch that lets you zoom by hand when you want a fast snap rather than a motorised move. The return button and the record button often sit on the handgrip too.

Autofocus, and why live operators switch it off

Modern autofocus can find a face, lock onto its eyes and hold it while it moves. On a phone and a vlogging camera it is excellent, and on a gimbal with one presenter walking towards it, it can be the right tool.

On a live show it is usually switched off, for reasons that have nothing to do with how good it is. Autofocus has to guess what the shot is about, and a stage is full of wrong answers. Two people on a sofa give it two faces to choose from. A presenter who turns away gives it nothing, so it searches and finds the brighter LED wall behind. A dark stage gives it too little contrast, so it hunts back and forth. Every one of those happens on air, and every one is visible as the picture going soft and sharp again.

Manual focus fails differently. When an operator loses focus, they know, and they know which way to turn. When autofocus loses it, the operator finds out when the director does.

Where it is reasonable is the camera nobody is standing behind: a PTZ on a single lectern, or a locked-off camera on a presenter who does not move much. Even then, check it through a rehearsal with the presenter actually moving, and have a plan for the moment it chooses the wrong thing.

How operators actually hold focus

Following a presenter who moves was covered earlier. These are the habits underneath it that make focus reliable.

Focus tight, shoot wide. Zoom all the way in on the subject's eyes, bring them sharp, then zoom back out to the shot you want. At the long end of the zoom depth of field is at its shallowest, so an error that would be invisible at the shot's framing is obvious, and correcting it there means the wider shot is right. This only works if back focus is set, which is why the two always go together.

Focus on the eyes, and on the nearer eye if the face is turned. An audience forgives soft ears and hair and does not forgive soft eyes.

Use marks. If the presenter will stand at a lectern, focus on the lectern during rehearsal and remember or mark that position on the demand. When they arrive there, you already know where focus is.

A rack focus, sometimes called a pull, is a deliberate move of focus from one subject to another in the same shot — from a product on a table to the person talking about it. It is a shot, not a correction, so it is rehearsed: both marks found, the speed agreed, and the move made on a cue, not by feel.

And check constantly. A presenter who has been standing still for five minutes may have leant back a few centimetres. The time to find out is while you are off air.

Lens types, side by side

What you will find on the front of the camera, and what it means for the operator.

The numbers on a zoom

• Zoom ratio is the long end divided by the short end. 8–160 mm is 20x.
• A 2x extender doubles every focal length and costs two stops of light.
• Minimum object distance is the closest a subject can be focused. On a long zoom it can be a metre or more.

How to do it

1. Put something with fine detail at roughly the distance you will actually be shooting — a test chart if there is one, otherwise printed text, a patterned fabric, or the edge of a lighting fixture.
2. Open the iris as wide as it will go. A wide iris gives the shallowest depth of field, which makes focus errors visible. Add neutral density or close the lights down if the picture is now too bright to judge.
3. Zoom all the way in on the detail and focus the lens until it is as sharp as you can make it.
4. Zoom all the way out to wide. Do not touch the focus ring.
5. If the wide shot is now soft, loosen the back focus ring — usually marked F.B or B.F, near the camera body — and adjust it until the wide shot is sharp. Tighten it again.
6. Zoom back in and check the tight shot is still sharp. Repeat until both ends hold focus without you touching the focus ring.

What goes wrong

Practice it

Answer before checking.

Framing, Composition & Movement

Where you point the camera and how you move it is the difference between footage and storytelling.

Shot sizes and composition

Framing is choosing what is in the shot and how it is arranged. Shot size describes how much of the subject is in frame: a wide shot sets the scene, a medium shot is the standard workhorse, a close-up shows emotion and detail. Knowing the standard shot sizes lets an operator deliver exactly what a director asks for. Composition is the arrangement within the frame — keeping the subject well placed, level, with appropriate space, and free of distracting background.

A few durable composition guidelines help: keep horizons level, leave a little room in the direction a subject faces or moves, place the subject off-center for a more natural image (the rule of thirds), and avoid awkward crops. These are starting points, not rigid laws, but they instantly make shots look more professional than dead-center, tilted, or cramped framing.

Support and movement

How the camera is supported determines how stable and how mobile it is. A tripod gives a rock-steady image and smooth, controlled pans (horizontal) and tilts (vertical) — the backbone of most live shows. Handheld is mobile and energetic but harder to keep steady. Specialty support — jibs, dollies, gimbals — enables sweeping or moving shots. Choosing the right support for the shot is part of the craft.

Movement should be motivated and smooth. A slow push or a gentle pan that follows the action looks intentional; a jerky, aimless move looks amateur. The principle for a beginner is restraint: a steady, well-composed static shot beats a shaky moving one every time. Master stable, smooth fundamentals before attempting fancy moves, and most live work will be well served.

Headroom, looking room, and where the eyes sit

Three things make an amateur frame recognisable, and all three are fixable in about a second once somebody has named them.

Headroom is the space between the top of the head and the top of the frame. Too much and the subject sinks to the bottom of the picture with an expanse of empty ceiling above them; too little and the frame feels cramped, or the top of the head is cut in a way that looks like a mistake rather than a choice. The rule that actually works is not about the head at all: put the eyes on the upper third of the frame, and the headroom follows. As a shot gets tighter, headroom reduces — a big close-up may legitimately cut the top of the head, and still looks right because the eyes are where they should be.

Looking room, sometimes called nose room, is the space in front of somebody who is not facing the camera square-on. A person looking to frame right needs more space on the right than on the left. Centre them instead and they appear to be pressed against the edge they are looking at, which reads as uncomfortable without the viewer knowing why.

The eyeline is where those two meet. The eyes are what an audience looks at, so the eyes are what you frame — everything else arranges itself around them. An operator who thinks in terms of "where are the eyes" rather than "where is the head" gets consistent frames without a rule book.

The line, and the cut that makes no sense

Two people are talking. One is on the left facing right; the other is on the right facing left. Draw an imaginary line through both of them and extend it across the room. Every camera stays on one side of that line.

This is the 180-degree rule, and it exists because of what happens when it is broken. Put one camera on the far side and cut to it, and the person who was facing right is suddenly facing left. The audience cannot tell whether they have turned round or swapped places, and for a second or two the room stops making sense. Nobody in the audience will say "you crossed the line" — they will just find the show slightly confusing and not know why.

It applies to more than interviews. A presenter and a screen, a panel and a moderator, a band facing an audience: all of them have a line, and all of them look wrong when a camera crosses it.

On a live multi-camera show the line is normally settled at the plot stage, before anybody arrives, by where the camera positions are drawn. That is the point at which it is cheap to fix. If you arrive and find your position is on the wrong side of it, say so early — during rehearsal it is a conversation, during the show it is a shot the director cannot use.

A move needs a reason, a start and an end

The commonest fault in amateur camerawork is not bad framing. It is movement with no purpose — a slow drift, a creeping zoom, a reframe that begins because the operator felt they should be doing something. On air it reads as restlessness, and it makes an audience aware of the camera, which is the one thing a camera should never do.

The rule that fixes it has three parts. A move needs a reason: something has changed and the frame must follow it, or the director asked. It needs a clean start: you begin from a held, correct frame, not from a drift already in progress. And it needs an end: you arrive at another held, correct frame and stop there, rather than trailing to a halt.

Between those, the move itself should be slow enough to be invisible and even enough that nobody can see you starting or stopping. A fluid head with its drag set properly does most of that work; a head set too loose jerks at the start, and one set too tight sticks and then jumps.

The hardest discipline is holding still. A held frame that is right is not the operator doing nothing — it is the operator deciding not to spoil it.

Support: what it does, and levelling it

Most live camerawork happens on sticks: a tripod with a fluid head. The head is what matters. Fluid drag resists your hand smoothly so a pan starts and stops without a jerk, and the counterbalance holds the camera at whatever tilt you leave it rather than flopping forward.

A pedestal raises the whole camera vertically on a column and rolls on a studio floor, which is how a camera changes height mid-show without the shot rising and falling. A jib puts the camera on the end of an arm for moves no tripod can make. Handheld and shoulder-mounted give mobility and cost stability, and are worth it only when the movement is the point.

Whatever it stands on, level it — properly, on the bubble, not by eye. An unlevel head is the single most common avoidable fault in live camerawork, and its signature is unmistakable: the horizon tips as you pan, so a shot that starts level ends up sloping. It cannot be corrected once the show starts, because correcting it means re-levelling and re-framing, and you will be on air.

Level the tripod first using its own legs or bowl, then mount the camera. Levelling the head to compensate for uneven legs works until you pan, and then it does not.

The rule of thirds, and when to break it

Imagine two lines dividing the frame into thirds from left to right, and two more dividing it into thirds from top to bottom. The rule of thirds says the important things in a picture look most natural placed on those lines or where they cross, rather than dead in the centre.

For a person, that usually means the eyes sit on or near the upper line. Put them there and headroom looks after itself, because the top of the head is then about where it should be for most shot sizes. Place a presenter who is looking across the frame on one of the vertical lines, with their looking room on the other side, and the frame feels balanced rather than parked.

It is a starting point, not a law, and live work breaks it constantly for good reasons. A presenter speaking straight into the lens is usually centred, because they are addressing the viewer and an off-centre frame makes it look as if they are talking to somebody beside the camera. A symmetrical set, a lectern with a logo, or a stage shot from the centre aisle all look right centred. And when a graphic will sit on one side of the frame, the subject is placed to leave room for it, wherever the thirds happen to fall.

The value of the rule is that it gives you a reason. Centring is fine when it is a choice; it looks amateur when it is what happened because the subject was in the middle of the viewfinder.

Balance, and what gives a frame its weight

A frame feels balanced or lopsided long before anyone could say why. The reason is visual weight: some things in a picture pull the eye harder than others, and a frame with all the pull on one side feels as if it is tipping.

Faces are the heaviest things in any frame; the eye goes to them first and returns to them. Bright areas are heavy, which is why a lit exit sign in the corner of a shot steals attention from the person talking. Saturated colours are heavy. Large objects are heavier than small ones, and things near the edge of the frame feel heavier than the same things near the middle.

Balancing a frame means placing a subject off-centre and letting something on the other side answer it: the space they are looking into, a second person, the lit screen they are presenting, a piece of the set. It does not mean symmetry. A small bright thing on one side can balance a large dim thing on the other.

On a live show the practical use is deciding what else is in the frame. Moving a camera slightly can take a distracting bright light out of the corner, or bring a lectern logo into the space beside a presenter so the frame no longer looks empty on one side. Those are small moves with a large effect on how professional a shot looks.

Lines, perspective, and leading the eye

Every room is full of lines: the edge of the stage, rows of seats, the truss overhead, the edge of an LED wall, a table, a corridor. How those lines sit in the frame decides whether the picture feels flat or deep, calm or tense, and where the eye travels.

Lines lead the eye along them. A row of seats running from the corner of the frame towards the presenter carries the viewer to the presenter. The same row running across the bottom of the frame just sits there. Choosing a camera position is often choosing which way the room's lines run.

Converging lines make depth. Shoot a stage straight on and its edges run parallel to the frame, and everything looks like it is painted on one flat surface. Move the camera to an angle and those same edges converge towards a vanishing point, and the stage has a front and a back. A wide lens exaggerates convergence and a long lens flattens it, which is part of why focal length changes the feel of a room.

Some lines work against you. A horizontal line — the top of a set, the edge of a screen, a horizon — running straight through a presenter's head or neck cuts them in two. A strong diagonal pulling out of the corner of the frame pulls the eye out with it. And vertical lines should stay vertical: tilt a wide lens up at a tall set and the verticals lean inwards, which looks like a mistake unless it is meant.

Camera height changes all of it. Lower the camera and lines rise in the frame; raise it and they fall. A presenter shot from slightly below eye level looks more commanding, from above looks smaller, and from eye level looks like a person talking to you, which is why eye level is the default for almost everything on a corporate stage.

Depth — foreground, subject and background

A screen is flat, and a good picture does not look it. The main way a camera operator creates depth is layers: something in the foreground, the subject in the middle, something behind.

The simplest layer is the background. A presenter against a plain wall two centimetres behind them looks pasted on. The same presenter a few metres in front of a set, with the set a little out of focus and a little darker, looks like they are standing in a place. Separation — distance, a difference in focus, a difference in brightness, a rim of backlight — is what lifts a subject off what is behind them.

Foreground is the layer operators forget. The back of an audience member's head soft at the bottom of the frame, a microphone on a stand, the edge of a lectern, a plant on the set: any of them tells the viewer there is space between the camera and the subject. Used carefully it turns a flat shot into one that feels like it was taken in the room. Used carelessly it covers the subject or distracts from them, so a foreground layer is usually out of focus, darker, and at the edge of the frame.

Angle adds depth too. A shot along a diagonal through a room has more layers in it than one taken square to the wall, because more of the room is at different distances from the lens.

Frames within frames

Sometimes the room hands you a frame: a doorway, an arch, the gap between two pieces of set, the uprights of a truss, the silhouettes of two audience members' heads with the stage between them. Composing the subject inside it is a frame within a frame.

It does three things at once. It directs the eye to whatever is inside. It adds a foreground layer, and so depth. And it says something about where the camera is — shooting through the audience says this is what it looked like to be there.

The inner frame should be darker or softer than the subject so it does not compete, and it should never cover the thing that matters. An audience member's head is a good frame until they move it, so a shot framed through the crowd is one you check constantly and are ready to lose. And like every compositional device, it is noticed when it is overused: one shot through the crowd tells a story, a whole show of them feels like a trick.

Open and closed framing

A closed frame contains everything the shot is about. The subject is fully inside it, nothing important is cut by the edges, and the picture feels complete and stable. Most planned shots on a live show are closed: the presenter at the lectern, the panel on the sofa, the wide of the stage.

An open frame suggests the picture continues beyond its edges. A subject is cropped by the edge, somebody is partly out of shot, a gesture leaves the frame, a movement runs past the edge. The viewer is made aware of a world outside what they are seeing, and the picture feels alive, energetic and less controlled. A handheld camera in a crowd, a tight shot of hands on a keyboard, a musician half out of the frame — these are open frames, and they belong to the kind of show that wants that energy.

The difference matters because each one is a choice with a meaning, and the mistake is producing one when you meant the other. A presenter whose elbow is accidentally cut by the edge of a mid shot is not an open frame, it is a bad closed one. The test is whether the edge cuts something because you chose it to, or because the frame is a few centimetres too tight.

What is behind the head, and where the edges cut

Most bad frames are not bad because of the subject. They are bad because of something the operator did not look at.

Look behind the head. A truss upright, a lamp stand or a lighting fixture directly behind a presenter appears to grow out of their head. A horizontal edge at neck height cuts them in two. A bright exit sign or a monitor in the background pulls every eye. The other camera, a crew member or a cable run can sit in the background of a shot for a whole segment without anyone noticing until the edit. A glance round the whole frame, not just at the subject, before every shot is the habit that catches these.

Look at where the edges cut. The frame edge should cut a person between joints, never at them. Cut at the neck, the elbow, the wrist, the waist, the knee or the ankle and the picture looks like it has amputated something. Cut between them — mid-chest, below the waist, mid-thigh, below the knee — and it looks deliberate. Shot sizes are defined along exactly those lines for this reason.

And look at the edges themselves. A sliver of something at the very edge of the frame — half a face, the corner of a screen — is more distracting than either including it properly or excluding it cleanly. Move a little and decide.

Safe areas, and leaving room for graphics

What goes out is rarely just your picture. A name and title appear in the lower third as the presenter starts talking. A logo sits in a corner. On a stream the picture might be shrunk into a box beside slides. On the big screens in the room it might be cropped to a different shape. An operator who frames without knowing any of that frames a shot the graphics will ruin.

The viewfinder's safe area markers help. The inner box, graphics safe, is where the switcher operator keeps text so it is never cut off on any display; under the current HD recommendation it sits at about ninety percent of the frame. The outer box, action safe, at about ninety-three percent, is where anything important in the picture should stay. Older equipment marks graphics safe at eighty percent and action safe at ninety, because older displays cropped more. Keep eyes, mouths and anything the audience must see inside the boxes.

Then frame for the graphic. If a name super comes up across the bottom, a mid shot of a presenter needs the super to sit below the chin, not across the mouth, which usually means a little more room below the face than you would otherwise give. If the stream puts the picture in a box on one side of the slides, the presenter should face into the slides rather than out of the screen. These are things to ask about in rehearsal, and to watch on the return feed once the graphics are running.

The big screens in the room — IMAG — are their own consideration. They are often a different shape from the broadcast picture, frequently cropped to a taller or wider area, and they are seen by an audience sitting a long way from them. A slightly tighter shot usually works better on IMAG than on a stream, and on shows with both, the director decides which one wins.

Zoom or move, and why they are not the same

A zoom and a camera move can both make a subject bigger in the frame. They do not look the same, and the audience feels the difference even when they could not describe it.

A zoom magnifies. Every part of the picture grows at the same rate, and the relationship between the subject and the background does not change: nothing in front of the presenter moves across them, and the background does not shift behind them. It looks like the viewer's attention is being pushed towards something.

A move — a track in on a pedestal or dolly, a crab to one side, a walk in on a handheld — carries the camera through the space. Things nearer the lens slide past faster than things further away, the background shifts behind the subject, and the room reveals its depth. It looks like the viewer is going somewhere.

A zoom is quicker to set up and needs no floor space, which is why live shows use far more zooms than moves. A good operator uses both on purpose: a slow zoom in to underline a moment in a speech, a crab round a panel to show there are four people and not just the one talking.

The zoom has one famous misuse. A zoom that creeps in and out through a segment because the operator is fiddling, or that is combined with a pan for no reason, reads as nervousness. On air, a zoom is slow, has a reason and a start and an end, exactly like any other move.

The development shot

A development shot is a shot that changes what it is about while it runs. The camera moves — tracks, cranes, crabs, pans with a zoom — and as it moves the composition turns into a new composition that means something the first one did not.

Start on the brand logo on the front of the lectern, rise and pull back to reveal the presenter behind it, keep pulling back to reveal the audience in front of them. One continuous shot has said: this company, this person, this room full of people listening. Cutting the same story would take three shots and three cuts.

What separates a development shot from wandering is that every point of the move is a usable frame, and the start and end are strong ones. The operator plans it, rehearses it, finds the marks for the start and the end, knows how long it takes, and the director knows exactly when it will land. On air it is smooth all the way through, because a bump halfway is visible in a way a bump in a static shot is not.

It is the thing that separates operating a camera from pointing one, and it is worth practising on an empty stage long before anyone asks for it.

Shooting for the cut — the other cameras' shots

On a multi-camera show nobody watches your shot on its own. They watch it cut against the shot before and the shot after, and a shot that is beautiful on its own can be useless in that sequence.

Know what the other cameras are giving. The return feed and the multiview show you, and on most shows the camera plan or camera cards tell you each camera's job. If camera one is on a mid shot of the presenter, a second mid shot of the same presenter from almost the same angle is a cut that looks like a jump. A cut between two shots of the same subject needs a clear change: a different shot size, or an angle at least thirty degrees different, and ideally both.

Match what should match. Two cameras on the same person should give them similar headroom and similar looking room, and their eyelines should be consistent with the geography of the room, so the viewer is never confused about where people are relative to each other.

Offer what is missing. When the director is on your colleague's close-up and you are free, find something the show can use next: a wider shot, a reaction from the audience, the person the presenter is about to introduce. A director who can see a useful shot on your camera in the multiview uses it.

And stay out of each other's shots. Know where the other cameras are pointing, move behind them rather than in front of them, and if you have to cross a line of sight, wait until that camera is not live.

Shot sizes, and what each one is for

These names are a shared language. When a director says 'give me a medium on camera two' they expect the same frame from everyone, and the value of the vocabulary is that nobody has to describe it.

Where to cut a person

The frame edge should fall between joints, never on them. This is why the shot sizes are defined where they are.

Safe areas under the current HD recommendation

• Graphics safe is about 90% of the frame. Text is kept inside it.
• Action safe is about 93% of the frame. Anything important in the picture stays inside it.
• Older equipment marks graphics safe at 80% and action safe at 90%, because older displays cropped more.

Cutting between two shots of the same person

• Change the shot size clearly, or change the angle by at least thirty degrees — ideally both.
• Keep headroom and looking room consistent between cameras on the same subject.

On the job

A panel of four sits on a low sofa in front of an LED wall. You are camera three, on a pedestal house left, and the camera card says "singles of the two nearest guests, and a development shot for the opening."

In rehearsal you find your singles first, and the problem appears straight away: from your position, the wall's bright edge runs across the second guest's neck, and a speaker stack is growing out of the first guest's head. You crab half a metre towards centre and lower the column. The edge now sits below the sofa back and the stack is out of frame.

Then the two singles are too similar to camera one's, which is on the same two guests from centre. You tell the director on comms, who changes your job to the far pair, and camera one keeps the near pair. The cuts between you now change angle properly.

Then the development shot. You start on the host's hands holding the cue cards, rise and pull out to the host, and keep pulling out until the whole panel is in the frame with the wall behind. You find the start mark and the end mark, tape both on the floor, and run it three times at the speed the host takes to read the welcome. The third run is clean all the way through.

None of this happened on air. All of it would have.

What goes wrong

Practice it

Answer before checking.

Supports, Pedestals and Handheld

The earlier chapter said a tripod is the backbone of most live shows and that support should suit the shot. This chapter is about the hands-on part: how the head is balanced, how a pedestal is driven, how a handheld camera is held so the picture does not wander, and how a camera is left safely when nobody is standing behind it.

A camera that fights its operator produces pictures that look like a fight. Most of what makes camerawork look smooth is set before the show, in the support.

Balancing the head

A fluid head is not just a pivot. It is designed to hold a camera at whatever tilt angle you leave it and to resist movement smoothly when you push it, and it can only do both if the camera is balanced on it.

Balance has two parts. The first is where the camera sits front to back. A camera and lens have a centre of gravity somewhere along their length, and the camera plate slides fore and aft on the head until that centre sits over the tilt axis. The test is simple: level the camera, take your hands away, and it stays level. If it noses down, slide it back; if it tips back, slide it forward.

The second part is counterbalance. A camera sitting above the tilt axis wants to fall forward or back as soon as you tilt it, and the head has a spring counterbalance that pushes back against that. Set it for the weight of the camera as it will be used — with lens, viewfinder, prompter, battery and anything else fitted. Correct counterbalance means that when you tilt down to the floor and let go, the camera stays there, and when you tilt up to the lighting rig and let go, it stays there too.

Only when both are right do you set drag. Drag is the resistance the fluid in the head gives to movement, set separately for pan and tilt. More drag makes small, slow moves easier and gives the camera a feeling of weight; less drag makes fast moves possible. Set it for the show: a speech gets more drag than a sports event.

Balance is redone whenever the camera changes. Add a prompter, swap to a heavier lens or put a large battery on the back, and a camera that was perfectly balanced tips as soon as you let go.

The pan bars and the locks

The pan bars are the handles you steer the head with, and on a pedestal they carry the zoom and focus demands. Set them where your hands naturally rest when you stand behind the camera at operating height, angled so your wrists are straight and tightened so they do not slip under pressure. A bar that rotates in its clamp halfway through a pan ruins the move.

Every head has pan and tilt locks, and they exist for the moments you let go. Whenever you step away from the camera, even for a second, the tilt lock goes on. An unlocked camera that is even slightly out of balance will slowly tilt on its own, and a heavy one tilting forward has enough force to break a viewfinder, a lens or a finger.

The locks are not a way to hold a shot on air. Operating with the drag set high and the lock half on feels steady and produces a jerk every time the lock slips. If a shot needs to be absolutely still for a long time, it is a locked-off shot, and it is set up as one.

Driving a pedestal

A studio pedestal is a heavy wheeled base with a column in the middle that rises and falls, and the head on top. It lets an operator move the camera smoothly across the floor and change its height on air, which a tripod cannot do.

The column is counterbalanced, usually by gas pressure, so the camera floats at whatever height you leave it. Set that balance for the camera's weight, and the column rises and falls smoothly under light pressure from the steering ring; get it wrong and the column either drifts up or has to be heaved.

The steering ring round the column steers the wheels. Pedestals have two modes. In crab mode all the wheels turn together and the pedestal moves in any direction without rotating, which is the mode for most on-air moves. In steer mode one wheel steers and the others follow, like a trolley, which is easier for driving the pedestal a long way across the floor between positions. Know which mode you are in before you push.

Moves are made with the steering ring, not the pan bars. Pushing on the pan bars pushes on the head, and the picture jumps. Before a move, turn the ring until the wheels already point the way you are going, because a pedestal whose wheels start pointing the wrong way lurches as they swing round, and that lurch is on air. Start slowly, move steadily, and slow before you stop, so the camera arrives rather than halts.

Round the base, cable guards sit just above the floor and push cable out of the way of the wheels. They must be set low enough to catch a cable, which means low enough to catch everything else, so look where you are going. The camera cable should be clamped to the pedestal with a loop, so a tug on the cable pulls the clamp and not the connector, and on a show with a lot of movement a second person — a cable assistant — pays out and gathers the cable behind the camera.

Tripods, spreaders and dollies

A tripod looks simple and fails in simple ways.

Spreaders hold the legs at a fixed spread so they cannot slide apart. A ground spreader sits on the floor between the feet; a mid-level spreader clips between the legs higher up and lets the feet go on uneven ground. Without one, a tripod on a smooth floor can splay slowly under the weight of the camera, which is a slow tilt on air and, eventually, a camera on the floor.

Height comes from the legs, extended evenly, not from a centre column if the tripod has one. A camera on a raised column is a camera on a stick, and it wobbles. Set the legs so the lens is at the height the shot needs — usually the subject's eye level — and so the pan bar is at a height you can hold for the length of the show.

Levelling is done with the bowl, not the legs. Most professional tripods have a half-ball under the head sitting in a bowl in the top of the legs. Loosen the handle underneath, move the head until the bubble is centred, and tighten. It takes seconds, and adjusting legs to level a camera takes minutes and still ends up wrong.

A dolly — a set of wheels that the tripod feet clip into — turns a tripod into something that can be rolled between positions. It is rarely smooth enough for on-air moves on an ordinary floor, and its wheels must be locked when the camera is operating, or the first firm pan rolls the whole camera.

Where people will pass close to a tripod, a sandbag on the spreader and gaffer tape over the legs' feet make it much harder to knock over and much easier to see.

Handheld and shoulder work

A handheld camera trades steadiness for freedom. The trade is only worth it if the operator gives back as much steadiness as possible with their body.

Stand with your feet apart, one slightly forward, knees soft rather than locked. Locked knees transmit every movement of your body into the camera; soft knees absorb them. Tuck your elbows into your body so the camera is braced against your torso rather than held out in the air by your arms. On a shoulder camera, the weight sits on the shoulder and your right hand on the handgrip steers rather than holds. Lean against a wall, a pillar or a riser whenever there is one.

Stay wide on the zoom. The wider the lens, the less your movement shows in the frame, and a handheld shot at the long end of a zoom is almost never usable. Get closer with your feet and keep the lens wide, and focus becomes easier too, because a wide lens has more depth of field.

Walk with your knees bent and roll your feet heel to toe, so the camera glides rather than bobs. Walking backwards is common and dangerous: agree with a colleague, a floor manager or a cable assistant that they will guide you with a hand on your back and a word before any obstacle.

Handheld is tiring, and a tired operator shakes. On a long show, rest the camera whenever it is not needed, and plan where you can put it down safely.

Gimbals and body-worn stabilisers smooth handheld movement much further and are their own skills. The basics here still apply underneath them: a gimbal cannot stabilise an operator who walks badly.

Jibs, cranes and robotic cameras

Some camera supports are not operated by the person using the camera, and knowing that is part of working near them.

A jib or camera crane is a long counterweighted arm that swings a camera up over an audience or down to the stage. It is operated by a trained jib operator, often with a second person on the camera controls, and it needs a clear zone around the whole arc of the arm and the counterweight end. The counterweight swinging round at head height is the danger most people do not see coming. Never walk through the arc, never lean on the base, and never take weight off one end: removing a camera from a balanced jib without holding the arm is how the other end comes down.

PTZ cameras and robotic heads are driven from a controller with a joystick, a zoom control and a set of preset buttons. The same principles of framing apply, with two differences. A preset recall moves the camera at a set speed along a path the operator does not control, so presets are recalled off air and the camera is then adjusted by hand. And the operator is often watching several cameras at once, so each one must be set to be safe when it is not being watched — exposure, white balance and focus set rather than left to wander on automatic.

Locked-off cameras

A locked-off camera is set on a shot and left there. Most shows have at least one: a wide of the stage from the back of the room, a camera on a lectern for a hybrid meeting, a backup camera recording the whole event.

Unattended means it has to be set for every change the show will throw at it, because nobody will be there to fix it. Every automatic that might change the picture during the show is turned off and set by hand: exposure for the brightest lighting state it will see without going too dark for the dimmest, white balance by preset or by card, focus manually on where the action will be, with enough depth of field to hold it. Pan and tilt locks go on firmly, and the zoom is left alone.

Then protect the shot. Sandbag the tripod, tape its legs, and secure the cable so a tug arrives at a clamp rather than at the camera. Put it where the audience cannot knock it and where no one will stand in front of it; if people must pass close, mark it and consider a barrier. If it records to itself, check it has the media and the power to last the whole show, not just the first session.

Agree the framing with the director before you walk away, and look at it on the multiview during the show. A locked-off camera that has been nudged, gone out of focus, or had someone stand in front of it looks fine to the person who set it up, who is now somewhere else.

Supports, and what each one is for

What each support gives the shot, and what it asks of the operator.

How to do it

1. Build the camera completely first — lens, viewfinder, battery, prompter, radio, anything that will be on it during the show.
2. Put the tilt lock on, level the head with the bowl, and set the counterbalance to its lowest setting and the drag to its lightest.
3. Slide the camera plate forward or back until the camera stays level on its own with the tilt lock off and your hands away.
4. Tilt the camera down about thirty degrees and let go. If it falls forward, raise the counterbalance; if it springs back up, lower it. Repeat tilting up.
5. When the camera stays wherever you leave it, set the pan and tilt drag for the show's style of movement.
6. Put the tilt lock on whenever you step away, and rebalance whenever anything is added to or removed from the camera.

What goes wrong

Preparing for the Shoot

Almost everything that goes wrong for a camera operator during a show was decidable before it: a position with a pillar in the way, a cable run across a fire exit, a shot nobody told you about, a prompter that arrived at the last minute and unbalanced the head.

This chapter is the work before the work — the meetings, the paperwork, the walk round the room, choosing where the camera goes and making it safe there, and what a rehearsal is actually for.

The production meeting, and what to ask

On a large show there is a production meeting before anyone builds anything; on a small one it is a ten-minute conversation with the director or the producer at the start of the day. Either way it is the cheapest moment in the whole job to find things out, and an operator who arrives with questions is more useful than one who arrives with a camera.

What you need to leave with is simple. What the show is and who it is for — a keynote streamed to thousands, a board meeting recorded for the archive, a concert on the big screens. How many cameras there are, which one is yours, and what your camera is for. Where it will be. What format and frame rate the show runs. Where the pictures go: a switcher, a stream, IMAG, a recorder, all of them. Who controls exposure and colour. Which comms channel you are on, and who is talking to you. When the rehearsal is, when doors open, and when the show ends.

And the things nobody volunteers: whether there is a teleprompter on any camera, whether there are lasers, pyrotechnics or haze in the show, whether any presenters have asked not to be shot from a particular side, and what to wear. Most live events expect crew in plain black so they disappear, and a camera operator in a bright shirt on a riser at the back of a dark room is the brightest thing the audience can see.

Scripts, running orders, shot lists and camera cards

The paperwork on a show tells you what will happen, in what order, and what is expected of your camera during it. It comes in a few forms, and the names vary between companies, but the jobs are always the same.

The running order, or rundown, lists every segment of the show in order with its timing: walk-in, welcome, first speaker, video, panel, break. It tells you where you are in the show at any moment, and it changes, so the version with the latest time on it is the one that counts.

A script, where there is one, has the words — what the host says, when a video plays, where the cues are. On a scripted show the director calls shots against the script, and an operator who follows along knows a shot is coming before it is called.

A shot list sets out the shots the director wants, segment by segment, for all the cameras. A camera card is your camera's part of that: a small card, often clipped to the camera, listing your shots in order with a number for each. On a heavily planned show the director calls "shot twelve, camera two" and the card says what shot twelve is.

A call sheet or schedule tells you when to be where: call time, rehearsal, meal breaks, doors, show and the expected finish.

What to do with them is the same on every show. Read them before rehearsal. Mark your camera's shots and anything that affects them — a move, a change of position, a prompter segment, a lighting change. Ask about anything that does not make sense while there is time to ask. And keep your card where you can see it without looking away from the viewfinder for long.

The recce — surveying the location

A recce, from reconnaissance, is a visit to the place before the shoot to find out what it will be like to work in. On a big show the camera supervisor does it with the director days before. On a small one it is you, walking the room when you arrive, before you unpack.

Look at the light. Where are the windows and where will the sun be at show time? Is the room lit for the audience only, or is there lighting for camera? Where are the bright things — screens, exit signs, LED walls — that will be in the background of your shots?

Look at the space. Where could a camera stand and see the stage, the lectern and the audience? What is in the way — pillars, hanging speakers, the control desk, the audience itself once it is seated? Is there a riser for cameras at the back of the room, and if not, will a camera at eye height see over the heads of a seated audience?

Look at the practicalities. Where is power, and how far is it from each position? Where can cable run from the camera to wherever the pictures go without crossing an aisle, a door or a fire exit? How do you get equipment in — lifts, stairs, loading dock — and how long is the push? Is the floor carpet, polished concrete or a raked auditorium, and will a pedestal move on it?

And look at the people. Where will the audience walk in, sit and leave? Where are the emergency exits and the routes to them? Where will the other crew be working? A position that is perfect for the shot and in the middle of the route the audience uses to reach the bar at the interval is not a position.

Choosing a camera position

Where a camera stands decides most of what it can do. Framing, focus and exposure can all be adjusted during the show; the position mostly cannot.

Start with the subject's eyes. For people talking, the lens is normally at or near their eye height, because that is the height at which we look at each other. For a presenter on a stage one metre high, that puts the lens well above a seated audience's heads, which is convenient; for a panel seated on a low stage, it puts the lens about where the audience's heads are, which is not.

Then the angle. A camera straight on to a lectern gets the presenter's face and a flat picture. A camera at an angle gets depth and a three-quarter face, and if the presenter turns towards the other side of the room it gets the back of their head. Positions are chosen as a set, so between them the cameras cover every direction the presenter might face, and so they all sit on the same side of the line.

Then distance and lens. The further back the camera, the longer the lens needed, the less depth of field it has and the more any vibration shows. A camera at the back of a ballroom on a riser that bounces every time somebody walks past will produce a close-up that bounces too.

Then sightlines, in both directions. What does the camera see — is there a clear view of every place the subject will be, with nothing crossing it when the audience stands? And what does the audience see — is the camera blocking anyone's view of the stage, and is the operator's shape going to be in anyone's eyeline for two hours? Cameras in the middle of an audience are sometimes unavoidable; they are then kept as low and narrow as the shot allows, and the seats directly behind them may need to be left empty.

Then the light. Stand at the position and look at the stage. Will a follow spot, backlight or projector beam point straight into the lens? Is the presenter's key light on the side of their face you will see?

And last, whether you can work there safely for the whole show: space to stand and move round the camera, no edge to fall from, no exit to block and no cable to trip the audience.

Setting up safely

A camera position is a small workplace inside somebody else's venue, often in the middle of a crowd, often in the dark. Setting it up safely is part of the job and not an extra.

Keep exits and aisles clear. A camera, a tripod leg or a cable across an emergency route is a hazard to every person in the room and it will be moved by the venue, usually at the worst moment. Know where the nearest exit is from your position and do not put anything in the path to it.

Mind edges. Camera risers and stages have edges, and an operator watching a viewfinder is not watching their feet. A riser that is more than a step high should have an edge barrier or handrail, and the camera should be set far enough from the edge that you can walk all the way round it without stepping off. On a raised position you are working at height, and the venue's rules for that apply to you.

Manage the weight. A system camera with a box lens on a pedestal is heavy, and so is a loaded tripod. Two people lift a camera onto a head, the tilt lock is on before anyone lets go, and a heavy camera is never lifted above shoulder height by one person. Check that a riser or stage is rated for the load you are putting on it, especially near its edges.

Protect the audience from the camera. A tripod leg that sticks into an aisle gets kicked, and a camera that gets kicked falls on somebody. Sandbag, tape and mark anything within reach of people passing.

Know the show's hazards. Lasers pointed into the audience can blind people and burn camera sensors. Pyrotechnics, haze and confetti cannons all have safety zones. Hot lighting fixtures near high positions burn hands. Ask about all of them at the briefing, and know where you must not be during those cues.

Running camera cable so it does not stop the shot

The camera cable is the part of the setup most likely to cause a fall, and most likely to stop a camera in the middle of a move. Running it well solves both.

Route it along walls and edges, not across open floor. Where it must cross a walkway, it goes under a cable ramp or a mat rather than tape alone, and never across a doorway or fire exit where it can be caught by a door or a hurrying crowd. Keep camera cable away from mains power runs, and cross power at right angles where the two must meet.

Leave enough cable at the camera for every move the camera will make. A pedestal that crabs three metres needs three metres of free cable plus a loop; a handheld operator who roams the front of the stage needs enough slack to reach the far side without dragging. Walk the moves with the cable connected before rehearsal, because the day you find out a cable is too short is not a day to find out on air.

Secure it at the camera. The cable is tied or clamped to the tripod leg or the pedestal with a loop between the clamp and the connector, so a tug arrives at the clamp. A camera cable that comes out of the camera mid-show takes the picture, the comms and the tally with it.

Label both ends and know where it runs. When a picture fails, somebody will have to follow that cable to find out why, possibly in the dark, and possibly while the show is still running.

The teleprompter on the lens

A teleprompter lets a presenter read a script while looking straight into the lens. A monitor lies face up in front of the camera, and a sheet of partly mirrored glass sits at an angle in front of the lens, reflecting the words towards the presenter while the camera looks straight through the glass. To the presenter the words appear to float over the lens; to the camera the glass is nearly invisible.

It changes the camera in several ways an operator must allow for. It is heavy and it sits far out in front, so the head must be rebalanced once it is fitted. The glass takes some light, roughly half a stop to a stop, so exposure changes. The hood round it can cut into the corners of the frame at the wide end of the zoom, which limits how wide the shot can go. And the whole arrangement is bulky enough that the camera is harder to move and harder to fit into tight positions.

It changes the shot too. The presenter is looking into the lens, so they are addressing the viewer, and that usually means a centred, straight-on frame. The camera cannot move much without the presenter visibly looking past it. The distance matters: too close, and viewers can see the presenter's eyes tracking along the lines of text; too far, and the presenter cannot read the text. A position and a focal length are found in rehearsal with the presenter reading, and then the camera stays there.

There is also a prompter operator, who scrolls the script at the presenter's speed. They are on comms, and on a show with a prompter they are a person the camera operator works closely with.

Rehearsal, and what it is for

A rehearsal is not a practice run of the show. It is the only time you can find and solve problems without an audience seeing them, and it is used for that.

Find every shot on your card and check it works from your position. If something is in the way, say so now. If a shot you have been given is too similar to another camera's, say so now.

Mark what you will need to find again. Tape small marks on the floor for pedestal positions and the start and end of moves. Note zoom positions and focus marks — where focus sits for the lectern, for the sofa, for the centre of the stage. Store presets if the lens has them. Write anything you will forget on the camera card.

Run every move at show speed with the cable connected, and run it again. Check nobody walks through it, nothing blocks it, and that it lands on a good frame.

Watch the lighting. Rehearsal is often the first time the show lighting states are run, and it is the time to notice that a backlight is in your lens or that a blackout leaves the presenter too dark to expose.

Listen to the director. Rehearsal is also when the director learns what each camera can and cannot give them, and when the calls, the numbering and the rhythm of the show get settled. An operator who speaks up once in rehearsal — "two can't see the lectern when the screen comes down" — saves the director discovering it on air.

In the show itself, the job is to deliver what was rehearsed, reliably. Changes still happen, and when they do you follow the director's call. What you do not do is try out a new idea on air that nobody has seen.

Working with presenters and talent

Presenters, speakers and performers are the reason the show exists, and many of them are nervous. A camera operator is part of their experience of the day whether they notice them or not.

On most live events the operator's job is to be invisible. You do not direct talent, move them, or tell them where to stand unless that is explicitly your role; that is the director's or the floor manager's job, and a presenter being given instructions by three different people will follow none of them. If something about a presenter's position will spoil a shot, tell the director or the floor manager.

Be courteous and brief when you do meet talent. A presenter fitted with a microphone before rehearsal may be standing next to your camera; introduce yourself if it helps, keep it short, and do not comment on how they look. If they ask where to look, tell them what the director has decided — the lens, the audience, or the prompter — and if you do not know, find out rather than guess.

Be careful what you say on comms. Radio mics are often live well before the show, headsets are easy to leave open, and a comment about a presenter heard in a room or on a stream ends careers. The rule is to say nothing on a headset you would not say in front of the person you are talking about.

And protect their dignity on camera. A presenter adjusting their clothing, stumbling on a step or wiping their face in a break is not a shot, and a good operator frames away from it without being asked.

The show's paperwork

Names vary between companies. The job each document does is always the same.

Ask at the production meeting

• What is the show, and where do the pictures go — stream, IMAG, record, broadcast?
• Which camera am I, where is it, and what is it for?
• What format and frame rate is the show?
• Who controls exposure and colour?
• Which comms channel am I on, and who talks to me?
• Is there a prompter, and on which camera?
• Are there lasers, pyrotechnics, haze or other hazards, and when?
• When are rehearsal, doors, show and wrap — and what do I wear?

On the job

You arrive at a hotel ballroom at seven for a nine o'clock conference. There are three cameras: yours is the long lens on a riser at the back of the room, centre.

The riser is already built, and before you unpack you stand on it and look. It is sixty centimetres high, with no edge barrier on the side facing the audience. You tell the production manager, who has a handrail fitted before the doors.

From the riser, a hanging speaker cluster sits in front of the lectern from exactly your lens height. You check the other end of the riser, where the view is clear, and ask whether the camera plan can move you there. The director agrees, as long as you stay on the same side of the centre line as camera one.

The cable from your new position would run across the back aisle. There is a service corridor behind the ballroom wall; the cable goes out through the side door, along the corridor and back in beside the control desk, twenty metres longer but out of every route the audience uses. You check the triax length reaches, and it does, with a loop to spare.

At the briefing you ask the questions you always ask, and learn two things nobody had mentioned: the CEO's opening uses a prompter on camera two, and there is a laser sequence before the product launch at eleven. You note the laser cue time on your camera card with "cap lens / point away", and you write down the lectern focus mark once rehearsal gives you one.

At nine, nothing about your camera is a surprise to anyone.

The Camera Operator on a Live Show

On a live multi-camera show, the operator is one instrument in an orchestra led by the director.

Multi-camera and communication

Most live events use several cameras feeding a switcher, and a director chooses which camera is live and calls the shots. The camera operator works to the director's instructions, heard over comms (intercom): get me a tight shot of the speaker, give me a wide, stand by camera two. The operator must frame the requested shot, hold it steady and sharp, and be ready when their camera is taken to air. Knowing whether your camera is live (often shown by a tally light) shapes what you can do — you reframe freely when off air, hold rock-steady when live.

Communication discipline matters as much as camera skill. Listen for your camera number, confirm you have the shot, and never make a big change while live unless asked. A great operator anticipates the director's needs, delivers clean usable shots, and is a calm, reliable voice on comms. The technical skill gets you the shot; the communication makes you part of the team.

Consistency and reliability

On a multi-camera show the cameras must match — similar exposure, colour, and look — so that cutting between them is seamless. Operators set up to a common standard and hold it, rather than each doing their own thing. A camera that is brighter, warmer, or framed differently than the others jars the audience every time the switcher cuts to it. Consistency across cameras is a shared responsibility and a mark of a professional crew.

Reliability is the operator's ultimate value. A director needs to trust that when they call for a shot, it will be there — exposed, focused, framed, and steady. The operator who consistently delivers clean shots on cue, communicates clearly, and stays calm under the pressure of live television is the one who keeps getting hired. Camera craft and crew professionalism together make the operator.

Practical sign-off

Camera skill is built behind the camera. The learner sets correct exposure and white balance, holds focus on a moving subject, frames the standard shot sizes, and operates to a director's calls on a small multi-camera shoot. A mentor signs off when the learner delivers clean shots on cue.

• Set correct exposure and white balance for the lighting
• Held sharp focus on a moving subject
• Framed wide, medium, and close-up shots cleanly
• Operated to a director's calls over comms on a live show

What the operator owns before the doors open

The difference between a reliable operator and one who is fine until something goes wrong is a list, worked through before anybody is watching. None of it is difficult. All of it is invisible when it has been done and obvious when it has not.

Power first, because it is the failure that ends a shot rather than degrading it. Know whether you are on mains or battery, and if the camera is on mains, have a charged battery on it anyway so that a pulled cable is a flicker rather than a black hole. Know where your spares are and how long one lasts in practice.

Then the signal path. Your output cable should be secured at the camera, dressed down a tripod leg rather than hanging straight off the camera, and given a service loop so a pan does not tug it. Check it reaches the truck and check somebody there can see your picture — a cable that is plugged in is not the same as a cable that is working.

Then the head. Level it, using the bubble and not your eye, because an unlevel head makes every pan drift uphill and there is no fixing it once the show starts. Set the drag so a pan moves smoothly under your hand rather than sticking and jumping.

Then the picture. White balance under the actual show lighting, not under the work lights, and do it again if the lighting state changes substantially. Set back focus. Agree with the director where your safe, locked-off framing is — the shot you return to when you have nothing else, which should be usable on air without you touching it.

Last, comms. Check you can hear the director and that the director can hear you, both directions, before it matters. Check your tally lights up when they take your camera. A camera whose tally is broken is a camera that will be reframed while live.

Taking a shot call, and the words that come back

A director does not ask for shots in ordinary conversation. They use a compressed protocol, the same on nearly every show, because it has to work over a headset with a band playing.

The shape is warning, then instruction. 'Standby camera two' means get ready; you are next. 'Camera two, tight on the lectern' is the shot you are being asked to make. 'Coming to you, two' means you are about to be live, and your frame should already be correct and held before it arrives. Then 'take two' or just 'two' — and your tally lights.

What comes back from you is short. Most shows run non-reciprocal comms: you hear the director and do not talk back except when you must, because eight operators acknowledging everything makes the headset unusable. The convention is that silence means yes. You speak when the answer is no — 'two, I can't see the lectern from here' — or when you have something the director needs and does not know, such as a presenter about to walk out of your frame.

Two habits mark out an operator who has done this. They frame during the standby, not during the take, so the shot is ready before it is needed. And they stay on the shot after the cut away from them, because a director may come back, and a camera that has already started reframing has nothing to come back to.

When it goes wrong while you are live

Things fail on air, and what separates a usable operator from a liability is what they do in the next three seconds.

If your shot is wrong and you are live, fix it slowly. A fast correction is more visible than the error — a lurch draws every eye, while a slow drift to the right frame is barely noticed. If it cannot be fixed slowly, say so on comms and let the director cut away.

If you lose focus badly, widen. A wider shot has more depth of field and is more likely to be acceptably sharp, and a slightly wide shot that is sharp is always usable where a tight soft one is not.

If something fails outright — the camera powers down, the lens jams, your picture disappears — say it immediately and plainly. 'Two is down.' The director needs to know they have one fewer camera, and they need to know before they call for you, not after. An operator who goes quiet and tries to fix it silently costs the show a shot that was counted on.

And when the failure is yours, say that too. Nobody on a show minds a mistake that was reported. They mind one they discovered.

Checking comms before it matters

A comms check is the first thing a camera operator does once a headset is on, and it is done properly rather than assumed.

Know your headset. Most have a talk button that works two ways: press and hold to talk while held, or tap it to latch the microphone on. A latched microphone on a camera headset transmits your breathing, your conversation with the person next to you and every cough into the ears of everyone on the channel. Talk by holding, and latch only when told to.

Know your channels. A show can have several — production, where the director calls shots; engineering, where vision and technical crew talk; and others for stage, lighting or sound. Your headset or belt pack may listen to more than one. Know which one the director is on, and which one you talk on.

Set the volume so you can hear the director over the room at its loudest — applause, a band, walk-in music — and not so loud that your ears are tired after an hour. If your headset has sidetone, the sound of your own voice in your ear, set that so you know when you are talking.

Then check in. Say your camera number and that you are on comms, and wait for the director or the person running the check to answer. Confirm you can hear, and that they can hear you. Do the same with the vision engineer if there is one. If anything is wrong — a crackle, a dead ear, no answer — say so, and say it now.

Moving without getting in anyone's way

A live show is a crowded place. Other cameras, other crew, the audience, presenters and performers all share the space an operator moves through, and a good operator is noticed only through their pictures.

Know what every other camera is shooting, so you never walk into another camera's shot. Move behind other cameras rather than in front of them. If you must cross in front of one, wait until it is not live and, if there is time, tell its operator or the director before you go.

Tell the director before any move that is not already on the plan. A camera that disappears from its position to find a better angle has taken away a shot the director was counting on, and until it is back on a usable frame the director has one fewer camera. "Two is moving to house right, thirty seconds" lets the director plan round you.

Move at the pace of the room. In a quiet moment of a speech, move slowly and quietly; a pedestal wheel squeaking across a silent room is heard by everyone. Handheld operators at the front of a stage stay low and out of the audience's eyeline wherever the shot allows.

And watch where crew need to be. A stagehand changing a set, a sound engineer running out a microphone or a floor manager cueing a presenter all need the same bit of floor you are standing on, often at the same time. When somebody needs to get past, the shot adjusts, not the stagehand.

What you will hear on comms, and what it means

These phrases are near-universal. A camera operator who does not recognise them slows the whole show down while somebody explains.

On the job

Forty minutes into a keynote, you are camera three, handheld, at the front of the stage. The director has been cutting between the wide on camera one and a mid shot on camera two, and has called you for two hand-held close-ups during the product demonstration.

Camera two's cable has worked loose at the pedestal, and its picture has gone. You hear the engineer say so on comms. Nobody has told the director yet, and the director is about to call a mid shot from two.

You say, clearly and briefly, "Director, three. Two is down. I can give you the mid from here." The director answers "Thanks three, stand by for the mid," and you move — slowly, low, behind the front row sightline — to the position where camera two's mid shot came from, frame it as camera two had it, with the same headroom and the same looking room, and hold.

The director takes you. The cut looks almost exactly like the shots before it.

When camera two is back, the director tells you to return to your close-ups. You wait until you are not live, move back, and find your first close-up before the demonstration starts.

What goes wrong

Practice it

Answer before checking.

Recording, Care and the Wrap

The show ends, the audience leaves, and the camera operator's job is not finished. There are recordings to hand over safely, cameras to put away in a state that means they work next time, a room to leave the way it was found, and a debrief where what went wrong gets fixed rather than repeated.

This chapter also covers the recording and the care that happen during the day, because most of what goes wrong at the end was caused earlier.

What gets recorded, and where

A live show is almost always recorded, and it is often recorded in more than one place.

The programme record is the switched output — the show as it went out, with every cut and graphic. It is recorded at the switcher or by a dedicated recorder, and on a stream the streaming platform may keep its own copy.

ISO records, for isolated, are recordings of each camera's picture on its own, whether it was live or not. They are what lets an editor fix a cut that was late, replace a shot that went soft, or cut a highlights package from angles that never went to air. On most shows they are recorded in the truck or control room on a multi-channel recorder, and the camera operator has nothing to do with them except to know that every moment of their camera is being kept.

Many cameras also record internally, to memory cards in the camera body. On a camcorder shoot this is the only record. On a larger show it may be a backup, or the way a roving handheld camera's pictures are captured when it is not cabled to the switcher at all.

What matters to the operator is knowing which of these applies to their camera. If the camera is recording to its own cards, the recording is theirs to start, check, change and hand over, and every other part of this chapter applies to them directly.

Checking you are actually recording

The most painful failure in camera work is finishing a shoot and discovering nothing was recorded. It is almost always preventable, and the prevention takes seconds.

Look for the signs, not the button. Pressing record is not proof of recording. A camera that is recording shows a red REC indicator in the viewfinder and on the body, and a timecode or counter that is running. Look at both after you press record, and look again at intervals during the day.

Beware the double press. On many cameras the record button toggles: one press starts, the next press stops. An operator who presses record, is not sure it took, and presses again has just stopped recording. Check the indicator instead of pressing again.

Know how much is left. Check the remaining time on the card and the battery against how long the next segment will run, before it starts, not halfway through.

Test before the show. Record ten seconds, play it back in the camera, and check that there is picture, that there is sound, and that it looks the way you expect. It is the only way to find a problem with the card, the format or the audio input while there is time to fix it.

Use the camera's safety nets where it has them. Many cameras can record to two cards at once, so the failure of one card loses nothing, or relay from one card to the next when the first fills. Many also have a pre-record buffer that keeps a few seconds before record is pressed.

Timecode, and why it has to agree

Timecode is a clock written into every frame of a recording as hours, minutes, seconds and frames. It lets an editor, or a machine, find exactly the same moment in several recordings.

Cameras run timecode in two main ways. Record run advances only while the camera is recording, so the recording has continuous numbers with no gaps; it is tidy but has no relationship to the time of day. Free run advances all the time, recording or not, usually set to the time of day, so every recording's numbers match what the clock on the wall said when it happened.

On a multi-camera shoot, free run is what lets the recordings line up. If every camera and recorder shows the same timecode at the same moment, an editor can drop them all on a timeline and they are already in sync. Getting them to agree is called jamming: the cameras are connected to a master timecode source, or to each other, and set to match, and on a long day they are re-jammed or connected to a timecode generator that keeps them agreeing.

For an operator, the practical habit is to check which mode the camera is in, check that its timecode matches what everyone else was told to use, and write down anything that went wrong with its timecode, so the editor is not left to discover it.

Media — handling, labelling and handover

A memory card that has been recorded on is the only copy of that work until it has been copied somewhere else. Treating it that way is the whole of media handling.

Never format a card you did not see copied. Formatting erases the card. The usual disaster is a full card put back in a camera by somebody who thought it was empty, and formatted. Only format a card when whoever is responsible for copying has confirmed that its contents are copied and checked, and format it in the camera that will use it rather than on a computer.

Make full and empty look different. A common system is a card wallet with one side for empty cards and one for full ones, and a strip of red tape across a full card, or its write-protect switch set, the moment it comes out of the camera. A full card never goes back in a pocket loose.

Label it. Camera, card number, date and show, written on tape on the card or its case, so there is no doubt later which camera it came from and in what order.

Hand it over properly. Full cards go to one named person — a media manager, the editor, the producer — directly, not left on a table. The handover is said out loud, "camera two, card three, full," and noted on a log. If there is no one responsible, it is you, and the cards stay with you until copied.

Do not delete individual clips in the camera. It is the quickest way to delete the wrong one and it can leave a card in a state that confuses the software later.

Keeping a camera log

A camera log is a short written record of what happened with your camera. On a big show it is a formal sheet; on a small one it is a few lines on the back of the camera card. Either way, it exists so the people who work with the recordings later know what they are looking at without asking you.

Write down the cards used and what is on each. Write down anything that went wrong, with the time or timecode: "cam 2 soft 14:02 to 14:03", "lost comms 15:40", "audio input 2 dead from 16:10". Write down anything unusual that somebody will want later: a shot you took that was not on the card, a moment of the show you know was special.

It feels like administration during a busy day. It is the thing that makes an editor trust you enough to book you again.

Cleaning the lens

A lens has coatings on its glass that control reflections and flare, and those coatings are softer than the dust that lands on them. Most lens damage is done by cleaning, not by use.

The order is always the same. Blow first: a hand blower pushes loose dust off without anything touching the glass. Brush second: a soft lens brush sweeps off what the blower did not move. Only then wipe, and only if there is still a smear or fingerprint, with a clean lens tissue or microfiber cloth and a drop of lens cleaning fluid on the tissue — never on the glass, where it runs into the edge of the lens. Wipe gently in a spiral from the centre outwards.

Never wipe dry grit. Wiping a dusty lens drags the grit across the coating and scratches it. Never use a shirt, a paper towel or a tissue from the catering table; all of them carry fibers and dirt and some are abrasive. And never breathe on a lens and wipe it with your sleeve in front of anybody who knows lenses.

Lens caps go on whenever the camera is not in use. They protect against dust, knocks and, as the next section explains, light that can do far worse damage than a fingerprint.

What damages cameras — sun, lasers, heat, water and condensation

Cameras are tough in some ways and very fragile in others, and the damage that ends a camera is usually one of a short list.

Lasers. A laser beam that sweeps across a camera lens during a show can burn permanent dead spots or lines into the sensor in a fraction of a second, and the lens concentrates the beam onto it. Concert and product-launch laser effects routinely point into the audience, and the camera is in the audience. Know the laser cues, and during them cap the lens or point the camera away from the beams.

The sun. Pointing a lens at the sun for long focuses it onto the sensor, much like a magnifying glass. The same thing happens through a viewfinder eyepiece: an eyepiece left facing the sun focuses it onto the viewfinder's screen and melts it. Never leave a camera pointed at the sun, and turn the viewfinder or cap it outdoors.

Heat. A black camera standing in sunlight overheats, and many cameras will shut down to protect themselves, sometimes during a shot. Shade it with a cover or an umbrella, and keep spare batteries out of the sun as well.

Water and dust. Rain covers exist for a reason and should be packed for any outdoor show. Dust at an outdoor festival gets into lens mounts, connectors and zoom mechanisms; caps on connectors, a lens cap between shots, and a blower at the end of the day.

Condensation. Moving a cold camera into a warm, humid room — out of an air-conditioned truck into a hot tent, or out of a cold van into a heated venue — makes water condense on the lens and inside the camera, exactly as it does on a cold glass of water. The front of the lens fogs, and inside, the moisture can damage electronics. Keep the camera in its closed case or a sealed bag while it warms up, which can take half an hour or more, and do not power it on while it is wet. Planning to arrive early enough for the camera to acclimatise is part of the call time.

Batteries — charging, travel and the rules for flying

Professional camera batteries are large lithium-ion packs that clip onto the back of the camera, usually on a V-mount or a three-stud gold mount. They are energy-dense and reliable, and they deserve the respect any concentrated store of energy deserves.

Know their real runtime. A battery's capacity is marked in watt-hours; divide it by the camera's power draw in watts for a rough runtime, then allow a margin, because batteries age, cold drains them faster and a viewfinder, a prompter or a wireless transmitter all draw from the same pack. Test a battery's real runtime on the camera it will be used with.

Rotate them. Charge in a known order, mark charged and flat batteries clearly — many teams turn a flat battery round in its bag or put tape on it — and take a damaged, swollen or unusually hot battery out of use immediately and tell somebody.

Transport them carefully. Terminals are covered so they cannot short against metal in a bag. Batteries that will not be used for a while are stored part-charged rather than full or flat.

And know the rules for flying, because they are strict and they apply to crew on tour. Under the international air rules most airlines follow, lithium-ion batteries go in carry-on luggage, never in checked bags. Batteries up to 100 watt-hours are generally allowed; between 100 and 160 watt-hours they need the airline's approval and are usually limited to two per passenger; above 160 watt-hours they are generally not allowed on passenger aircraft at all and have to be shipped as dangerous goods. Many large camera batteries are just over 100 watt-hours, and the marking on the battery is what the check-in desk will read. Airline rules vary and change, so check with the airline before every trip.

The wrap

The wrap is the end of the shoot, and it has an order, because doing it in the wrong order is how things get lost, broken or left behind.

Wait for the release. Cameras are not struck when the last speaker finishes; they are struck when the director or the production says so, usually with something like "that's a wrap, cameras clear." There may be a final shot, a group photo on the stage or a pickup of something that was missed.

Secure the recordings first. Before anything is unplugged, cards are stopped, taken out, marked full, labelled and handed over or put somewhere safe. A card lost in the rush of a strike is the one thing on the list that cannot be replaced.

Power down properly. Stop recording, turn the camera off with its own switch, and on a system camera ask for the power to be removed from the CCU before anyone unplugs the camera cable.

Then take the camera apart in the reverse of how it was built. Tilt lock on. Lens cap on. Prompter, battery and accessories off. Camera lifted off the head by two people if it is heavy, and put straight into its case. Fiber connectors capped the moment they are unplugged.

Cable last, and coiled properly. Camera and signal cable is coiled over-under: each loop is made the opposite way to the one before, one rolled forward over the hand and the next rolled back under it, so the twist each loop puts into the cable is taken out by the next. A cable coiled that way lies flat and runs out straight next time; a cable wound round an elbow stores a twist in every loop and fights whoever uncoils it. Both ends are capped or taped, the coil is tied near one end, and every cable is counted back into the case. Cable ramps and mats lifted, and tape pulled up off the floor.

Pack as it came. Every item goes back into the case it came out of, in its place, and the cases are counted against the list. Small accessories — plates, shoes, lens supports, headset adapters, rain covers — are the things left behind, so they are checked specifically. Lift heavy cases with two people, push them rather than drag them, and load the vehicle with the heaviest at the bottom.

And leave the room as you found it. Floor marks and tape off, risers clear, rubbish taken away, and nothing of yours in anybody else's space. The venue's view of the crew depends on the last hour, not the first.

The debrief, and reporting faults

A debrief is a short conversation after the show about what worked and what did not. On some shows it is formal; on many it is five minutes around the truck. Either way it is where problems become fixes rather than habits.

Say what went wrong, including what was yours. A camera that went soft for a moment, a missed call, a cable that came out — the director may already know, and hearing it from you, with the reason and what you would do differently, is what makes you trusted. Say what got in the way, too: a position that did not work, a shot that was not on the card, comms that were hard to hear.

Report equipment faults while they are fresh and before the kit goes back. A camera or lens with a fault is labelled on the item itself — a tag or tape saying what is wrong, when it happened and who noticed — so the next person does not pack it for a show. A faulty cable is marked at both ends and set aside, not coiled back in with the working ones, because a cable with an intermittent fault coiled into a case is a fault waiting for the next show. The fault is also written on whatever form the company uses, and damage reported honestly, however it happened.

Finish the paperwork: camera logs, media logs, the equipment return list, timesheets. It is the least interesting part of the job and the part that decides whether the recordings can be used and the kit can be sent out again.

Battery limits for air travel

The limits most airlines apply to spare lithium-ion batteries under the international air rules. Always check with the airline before travelling; rules vary and change.

Media rules that prevent the worst day

• Never format a card until the person responsible confirms it is copied and checked.
• Mark a full card the moment it comes out of the camera — write-protect or red tape.
• Label every card with camera, card number, date and show.
• Hand cards to one named person, out loud, and log them.
• Format in the camera that will use the card, never on a computer, and never delete individual clips in the camera.

Cleaning a lens, in order

• Blow off loose dust with a hand blower.
• Brush off what remains with a clean lens brush.
• Only then, if needed, wipe with lens tissue and a drop of fluid on the tissue, in a spiral from the centre.

How to do it

1. Stop recording and confirm the REC indicator is off before removing the card.
2. Take the card out and immediately set its write-protect switch or put red tape across it.
3. Label it with camera, card number, date and show.
4. Enter it on the media log with what is on it and anything that went wrong while it was recording.
5. Hand it directly to the named person responsible for copying, saying out loud which camera and card it is.
6. Do not format that card, or put it back in a camera, until the person copying has confirmed its contents are copied and checked.
