A Checklist to Work Through Before Committing to a Lighting Plan

Before anyone talks about mood or colour, find out what the cameras in the room can actually cope with. A lighting plan is judged on screen first and by the people standing under it second, so the camera specification is the first thing to put on the table. Ask which models will be used, what exposure range the operators are comfortable with, and whether the shoot is single camera, multi-camera or live to air.

I am an audio engineer rather than a lighting designer, but I sit in enough studio planning meetings to see the same pattern: lighting is agreed in the abstract, then the cameras arrive and the shaders find the key light too hot on one side of the set. Writing the camera requirements down first, with the person who will shade them, removes most of that argument before it starts.

Callum, who designs our lighting plans, asks for the same short note every time: camera type, intended lens range, the lowest and highest light levels the crew expect to work at, and whether the picture will be matched across several cameras. That note is cheap to write and shapes everything that follows.

• Camera models and sensor sizes in use
• Lens range and typical shot sizes
• Target exposure and any shading limits
• Single camera, multi-camera or live

The next check is the space. Ceiling height decides how far lamps can sit from the talent, and that distance affects spill, heat and how much of the set you can light without flooding the floor. Measure it, along with the usable grid or bar length and any fixed obstacles such as ducting, sprinklers or monitors on brackets.

Walls and floor matter too. A pale floor bounces light back up into faces and changes the contrast you thought you had planned, while a dark cyclorama swallows light and needs more output to read as intended. If the studio is shared with other productions, ask what has to be struck and re-hung between sessions, because a plan that takes two hours to rebuild will quietly stop being used.

Take photographs of the room from the camera positions and keep them with the plan. They are far more useful in a review than a description, and they let someone who has never visited the space ask sensible questions about it.

• Ceiling height and grid or bar positions
• Wall, floor and backdrop colours
• Fixed obstacles and access for ladders
• Time available to rig and strike

It is tempting to choose lamps first and sort out the supply afterwards, but the order should be reversed. Find out how many circuits the room has, what each is rated for, and whether dimmer channels and control cabling already exist or must be added. A plan that needs more power than the building offers is not a plan, however good it looks on paper.

Heat deserves the same attention. Tungsten lamps warm a small studio quickly, which affects performers, equipment and the air handling, while modern LED fixtures draw less but bring their own concerns about colour consistency and flicker on camera. Ask for test footage or a short trial before committing to a whole rig of one type.

Control is the quiet third item. Decide who will operate the lighting, from where, and whether presets need to be recalled quickly during a live show. A desk the operator finds confusing will be left on one safe state, and the design you paid for will never be seen.

• Available circuits and their ratings
• Dimming and control protocol in use
• Air handling and expected room temperature
• Who operates the desk, and from where

Producers and designers often use the same words to mean different things. Soft, warm, punchy and natural can each describe several quite different set-ups, so ask for reference images and write a sentence or two describing the intended result. Include what must not happen, such as hard shadows on the presenter's face or a washed-out background.

Talk about separation as well. Most studio sets need the talent to stand clear of the background, and that usually means a balance of key, fill, back and background light that suits the set design rather than a standard recipe. Share the set drawings or a rough model early so the lighting can be planned around real surfaces and colours.

If several programmes will use the same studio, agree which look is the default and which are variations. Designing for one show and expecting the rest to cope is a common source of compromise, and it is easier to settle in a meeting than on the day of a recording.

• Reference images for each programme
• A written sentence on the intended mood
• Set drawings or colours of key surfaces
• Default look and permitted variations

Cost is more than the price of the fixtures. Count rigging hardware, cabling, safety bonds, control equipment, installation time and the cost of replacing lamps over the next few years. A design that looks inexpensive at purchase can become expensive if every bulb change needs a hire platform or a specialist visit.

Ask what can be reused. Fixtures already in the studio, grid positions that suit the new plan and cabling in good condition all reduce the bill, and a sound design says so openly rather than starting from an empty room. Equally, if something existing is holding the picture back, the plan should name it and give a reason.

Finally, check who will look after the system. Someone should own the patch list, the focus notes and the spare lamps. Without a named person, small faults accumulate until the rig no longer matches the paperwork, and the next plan has to begin with a survey of what is actually up there.

• Rigging, cabling and control, not just fixtures
• Which existing equipment stays
• Lamp life and the cost of replacements
• A named person for patch and focus notes

With the room, the cameras and the budget described, the questions for the designer become straightforward. Ask for a plan view and a simple lighting schedule, and ask how the design behaves if one fixture fails mid-recording. A good answer is specific about which lamps are critical and which are there for polish.

Ask how the plan will be handed over. Focus charts, patch lists and a short note on how to recall each look are the difference between a design that works for a month and one that works for years. If the crew will rebuild it themselves, ask to see the documentation before the work starts, not afterwards.

And ask what the designer would leave out. Someone who can say which fixtures are optional, and what you would lose without them, is usually working to your brief rather than to a catalogue. That honesty is worth more than any extra lamp on the grid.

• Plan view, schedule and patch list
• Behaviour if a key fixture fails
• Handover documents and recall notes
• Which elements are optional
