A Checklist for Judging a Broadcast Lighting Plan Before You Approve It

Start with what the camera will actually see

A lighting plan is easy to admire on paper and hard to judge until the cameras are running. Before you approve one, ask who has looked at it from the camera position rather than the floor. Ask which shots the plan was drawn for: a wide establishing shot, a two-person interview, a close-up on a presenter at the desk. Each of those asks something different of the key light, the fill and the background.

A good plan states its assumptions plainly. It names the camera positions, the lens range, the expected exposure and the distance from talent to set wall. If any of these is missing, the plan is describing a room, not a programme. Ask for them in writing, and check them against the show format you have actually commissioned, not the one first discussed months ago.

• Which camera positions and lens ranges was the plan drawn for?
• What exposure and sensitivity does it assume?
• Does it cover the widest shot as well as the close-ups?

Colour consistency across fixtures and across the day

Colour is where many otherwise sound plans quietly fail. Ask which fixtures are specified, whether they share a colour temperature and how closely their output is matched from unit to unit. A rig that looks right when installed can drift as fixtures age, or when a replacement arrives from a different batch. The plan should say how that is handled.

Mixed sources deserve a direct question. Daylight through a studio door, practical lamps on the set, video walls and LED panels all carry different spectra. Ask how the plan keeps skin tones steady when these combine, and whether camera shading has been discussed alongside it. Lighting and camera control are cheaper to settle together than to correct separately once the show is on air.

• Are all key and fill fixtures matched in colour temperature?
• How is drift handled as fixtures age or are replaced?
• What is the plan for daylight, practicals and screens?

Power, rigging and the weight of the ceiling

The attractive part of a plan is the look. The part that causes delay is the infrastructure behind it. Ask for a power schedule showing the load per circuit and the total demand, and compare it with what the building can actually supply. LED fixtures draw less than older tungsten units, but dimmer racks, data distribution and ventilation still need sizing, and they are often assumed rather than checked.

Rigging deserves the same scrutiny. Confirm the safe working load of the grid or trussing, and who has verified it. If fixtures are to be hung at a height, ask how they will be reached for lamp changes, focusing and cleaning. A plan that cannot be maintained safely will be maintained badly, or not at all, and the look will suffer within weeks.

• Is there a power schedule per circuit and in total?
• Who has verified the load rating of the grid or trussing?
• How will high-hung fixtures be reached and serviced?

Can the crew run it on a normal working day

Operating practicality is half of the brief, and it is the half most often left out of the discussion. Ask who will run the lighting on a typical day and how many changes the plan expects between segments. A control desk with stored states can turn a complicated rig into a few reliable choices, but only if those states were built with the operators and written down.

Ask also what happens when the lead designer is not there. Is there a simple record of the focus positions, the stored looks and the patching? A plan that depends on one person remembering everything is a risk to the schedule. The best test is whether a competent technician who has never seen the studio could bring up a reliable general look from the documentation alone.

• How many scene changes does a typical show require?
• Are stored looks and patching documented for the crew?
• Could a new technician set a safe general look unaided?

Live events bring different questions

Studio plans and live event plans share principles but not constraints. At an event, the get-in is short, the venue sets the limits and the lighting has to serve both the audience in the room and the cameras. Ask how the plan balances stage look against camera exposure, and what the compromise is when the two pull apart. This is usually a decision about priorities, so it should be made deliberately.

Ask about time as well. How long does the rig take to install, focus and lock off, and how much of that falls before the cameras arrive? A plan that needs more rigging time than the venue allows is not a plan, however good the drawing. Ask what the fallback is if half the time is lost, and which elements of the look would go first.

• How is stage look balanced against camera exposure?
• How long are install, focus and lock-off expected to take?
• What is dropped first if time is lost?

What a sound plan should leave you able to explain

A final test is whether you can explain the plan to someone else. If you can say, in a few sentences, what the look is, what it needs from the building and how it will be run, you probably understand it well enough to approve it. If you cannot, the plan has not yet told you what you need to know, and it is reasonable to ask for another pass.

Keep a short record of the answers you were given. Dates, loads, fixture counts and assumptions about the programme all have a way of drifting during a project, and a written note makes later conversations calmer. It also gives anyone you bring in later, whether a new technical director or an outside engineer, a fair starting point for judging the work.
