The Tools We Use to Build a Lighting Plot for a Live News Set

Starting with paper before any fixture goes up

Every lighting plot we deliver begins as a scaled plan of the studio, drawn before anyone climbs a ladder. Priya Nair marks the set pieces, the presenter positions, the camera shots and the ceiling grid, then overlays the fixtures she expects to use. Working on paper first means we find clashes early: a desk edge that throws a shadow across a co-host, or a monitor wall that will pick up a reflection from a key light.

I am a camera operator, so I read these drawings from the lens side. I look for the angle each camera sees the face from and ask whether the light arrives from a flattering direction for that specific shot. A plan that looks tidy from above can still leave a presenter flat or half in shadow from the camera's point of view.

The plan is also the document the crew keeps. When a lamp fails during a long programme, whoever is on the rig can find its role at a glance and swap it without guessing what the replacement should do.

Soft sources and why we favour them for faces

For presenters, the workhorse in most of our plots is a soft source: a fixture that spreads light through a large diffusing surface instead of throwing a hard beam. Soft light is forgiving. It smooths skin texture, keeps shadows gentle under the eyes and nose, and lets a presenter lean or turn without stepping out of a narrow bright spot.

We pair soft key lights with a modest fill, enough to lift the shadow side without erasing shape. Too much fill makes a face look flat on screen, and flat faces make a news set look cheap however good the desk is.

Hard sources still have a place. A focused fixture gives us a gentle edge of light on hair and shoulders, separating the presenter from the backdrop, and it can pick out a texture on the set. We use these sparingly and aim them with care, because a hard source that drifts a few degrees shows up immediately on camera.

Controlling colour and keeping it steady

A plot only works if the light matches from one fixture to the next. Priya checks colour temperature with a handheld meter and standardises the fixtures on the key and fill positions, so skin does not turn slightly warm on one side of the face and cool on the other. Mixed sources are the usual culprit, such as a daylight window competing with studio lamps.

In a studio with windows, we cover or flag them and treat the room as a closed box. Daylight changes through the afternoon, and a live programme that runs across it would otherwise drift in colour without anyone noticing until they watch the recording back.

We also set the cameras' white balance against a known reference under the final lighting, not under worklights. It is a short step, but skipping it is behind many of the odd skin tones people complain about on small studio productions.

• Windows covered so daylight cannot drift the look
• White balance set under final lighting

Dimming, control and long-programme stability

The control side matters as much as the fixtures. We run lamps through a dimming desk so levels can be set, saved and recalled, which keeps the look identical from rehearsal to air. A saved state also means a different crew on the next shift starts from the same place, not from someone's memory.

Long live programmes put heat and wear on a rig. We leave fixtures to settle after switching on, because output and colour can shift slightly as they warm. We also avoid running lamps at the very top of their range for hours, which leaves headroom if the set needs a lift mid-programme.

Cabling is part of the method too. Tidy, labelled runs mean a problem can be traced in a minute instead of ten, and in a live show a ten-minute search is not an option.

Checking the result through the camera, not by eye

Our eyes adjust to a room quickly, which makes them poor judges of a lighting setup. So the final check is always on a monitor, with a presenter or stand-in sitting in position. I frame the standard shots and look at faces, the desk surface, the backdrop and any bright points that might clip.

We look at exposure with a waveform display as well as the picture. A face can seem fine on a monitor yet sit close to the limit of the sensor, and the waveform shows how much room there is before skin tones start to burn out.

Then we move. A presenter who stands, walks to a screen or turns to a guest takes the light differently at every mark, so we walk each position and note where the look changes. Any problem we find is fixed with a small nudge to a fixture, not a rebuild of the plot.

• Waveform used to confirm exposure headroom
• Every presenter mark walked before sign-off

Keeping a record the next crew can use

When the rig is right, we write it down. The record holds the plan, the fixture list, the saved dimmer states and the colour settings, along with notes on anything that behaved oddly. It is short and plain, written for a technician who was not there.

This is the quiet part of lighting design, and it is what makes a look repeatable across weeks of programmes. A set that is lit well once but never documented tends to drift as people adjust things to fix problems and never put them back.

We revisit the record after the first few live shows, because real use shows what rehearsal missed. A presenter who sits lower than expected, or a guest chair that catches a reflection, are small changes that belong in the notes.
