Starting with the set, not the lamps
We also ask what the cameras will see. A wide establishing shot shows the set, the backdrop and the grid above it, while a tight close-up shows only a face and a patch of wall. The plot has to hold up in both. That means noting lens choices, camera positions and the height of the shots before a single lamp is hung, because a lighting angle that flatters in one framing can throw an ugly shadow in another.
- Presenter and guest positions marked on the floor
- Camera positions and likely shot sizes
- Set colours, reflective surfaces and practical lamps
- Audience position, if there is one
Drawing the plot and choosing the colour temperature
Once the positions are fixed, the plot is drawn: a plan view with each fixture, its position on the grid or stand, its purpose and its channel number. We keep it plain. A key light, a fill, a backlight for each position, then separate lamps for the set and the background. The aim is a drawing that a rigger can read without us standing beside them, and that still makes sense to an engineer opening it months later.
Colour temperature is decided at this stage, not at the end. Mixing tungsten-balanced lamps with daylight sources, or with the window at the side of the studio, is a common cause of faces that drift between warm and cold from one shot to the next. We settle on one balance for the whole studio, check that every fixture can reach it, and note any practical lamp or screen that will need a gel or a different setting to match.
The rigging day
Rigging is slower than people expect and it is where a good plot is either respected or quietly compromised. Fixtures are hung, safety bonds attached, cables dressed and every lamp patched to its dimmer channel. We work through the plot in order rather than lamp by lamp as they come off the truck, because it lets us catch a missing fixture or a cable that is a metre short while there is still time to fix it.
While the crew works, one of us stays at the desk labelling. Channel numbers on the plot, on the console and on a strip of tape at the fixture itself should all agree. It sounds fussy, but a mislabelled channel found during rehearsal costs far more time than ten minutes of checking at the start. We also keep a short written note of anything that deviates from the drawing, so the plot and the real rig stay the same document.
- Safety bonds and clamps checked on every hung lamp
- Channels labelled at the console and at the fixture
- Deviations from the drawing noted as they happen
Focusing and balancing against the cameras
Focusing is done with a person standing in each position, ideally someone of similar height to the real presenter, with the cameras live on monitors. We set the key lights first, shaping the beam so it lands on the face and not on the set behind, then add backlight until the shoulders separate from the background without a hard rim. Fill goes in last and usually lower than people expect, since a little shadow gives the picture shape.
Balance across the cameras matters as much as the look from any one of them. If the key is a stop brighter on the left of the set than on the right, the vision mixer or the camera operator ends up compensating all show. We walk the stand-in across the whole acting area, watching the waveform and the pictures together, and adjust until faces sit at a steady level wherever the presenter moves.
Dimming, cues and the checks before doors open
Dimming control is where the plot becomes a show. We programme a small number of well-named looks: a rehearsal state, a standby state, the main presenter look and, where the programme needs it, a reduced look for packages or an audience wide shot. Fade times are set by eye on the monitors, since a fade that feels smooth in the room can look abrupt on a camera with a fixed exposure.
Before the presenter arrives we run every look from the console, then run them again from the cues the gallery will use. We check that nothing flickers at low levels, that LED fixtures dim cleanly on camera and that the audience lighting does not spill onto the set. A last walk of the studio floor catches anything that moved during rehearsal, such as a stand nudged by a passing trolley.
- Named looks saved and recalled from the gallery cues
- Low-level dimming checked for flicker on camera
- Spill from audience lighting onto the set checked
What we leave behind
At the end of the work the client receives the finished plot, the channel list, the saved looks and a short note on how the rig is meant to be used. We would rather a team could run the lighting themselves on a quiet Tuesday than depend on us for every change. That is why the paperwork is as much a part of the job as the lamps.
We also write down what we would change next time: a fixture that sits awkwardly, a stand that could move to the grid, a window that needs a blind. These are small notes, but they are the ones teams thank us for six months later, when the schedule is busy and the first sign of a problem is a shadow on a presenter's face.
A lighting plot that works on air is mostly the result of ordinary habits: asking what happens on the set, choosing one colour balance, labelling carefully, balancing against the cameras and checking every look before anyone arrives. None of it is glamorous, but it is what keeps a presenter looking the same from the first rehearsal to the last shot. If your studio rig has drifted from its drawing, start there.
