One Evening Bulletin, Three Different Faces: A Lighting Case

The call from Priya

Priya manages a small independent studio that produces a live evening news bulletin and a weekly interview show. She rang us in the early weeks of autumn with a complaint that sounded simple. Her presenters looked healthy and warm at the opening of the programme, and noticeably greyer and flatter by the closing headlines. Viewers had started to comment, and the director had begun to dread the last ten minutes.

She had already tried the obvious remedies. The make-up artist had changed products, the wardrobe had been adjusted, and the cameras had been white balanced twice before each show. Nothing held. I said I would come and watch a full broadcast from the gallery rather than guess from a description, because lighting problems over a long programme rarely reveal themselves in a quick walk around an empty set.

What we saw in the gallery

I spent an evening beside the director, watching the monitors and a handheld meter. The first thing that stood out was the set's mixture of sources. The news desk was lit by older fixtures that had been replaced piecemeal over several years, so the colour of the light varied from one lamp to the next. Individually each looked acceptable. Together they pulled the skin tones in slightly different directions.

The second thing was the passage of time. Over the length of the bulletin the output of the oldest units drifted, and a window at the side of the studio, shuttered but not sealed, let in the last of the evening daylight at the start of the show and none at the end. The cameras kept correcting for the change, which is why nobody could pin it down on any single device.

• Mixed fixtures with differing colour output on the desk
• Output drifting as the older lamps warmed through the show
• Leaking daylight at one side of the studio
• Cameras compensating quietly, hiding the cause

Drawing up the plan

Our brief was to make the look steady, not to rebuild the studio. Tom Eastwood, our lighting designer, measured the set at several points and proposed a plan built around a matched family of fixtures at consistent colour temperature for the desk, with the key, fill and back light positions fixed on paper so any engineer could restore them after a rig change.

We kept as much of Priya's existing equipment as made sense. Two fixtures were good enough to remain as background wash once they were checked against the new ones. The plan marked what to replace, what to keep, where each unit hung, and the dimming levels to record on the desk. It was a short document, written so a freelance lighting operator could follow it without asking us.

Taking care of the daylight

The leaking window turned out to matter more than the fixtures. A live set that shares its light with the outside world will change over the evening however carefully it is lit. We recommended a simple, properly fitted blackout covering so the studio was a closed environment from the first rehearsal to the last headline.

This is a cheap job compared with new lamps, and it is often skipped because it feels like building maintenance rather than television. In Priya's case it removed the biggest variable at a stroke. Once the set stopped changing with the weather outside, every later decision about levels and colour became easier to make and easier to trust.

• Fit a proper blackout to any window near the set
• Keep rehearsal and broadcast conditions identical
• Record fixture levels so they can be restored

Testing across a full programme

A lighting setup judged only in rehearsal can look perfect and still fail at the end of a long show. So we asked Priya to run the new rig through a complete dress bulletin at its normal length, with presenters seated throughout, while we compared frames from the opening and the close at the gallery.

The skin tones now sat close together at both ends. We made two small adjustments to the fill on the second presenter's side, noted the final levels on the plan, and left Priya with a short checklist for the start of each production day. She later told me the director had stopped dreading the last ten minutes, which is the only review that matters on a project like this.

What I take from it

The case taught me, again, that consistency is a quality in its own right. A lighting plan for a live set is judged over the whole running time, not at the moment the show begins. Matching the fixtures, closing off stray daylight and writing down the levels did more than any single piece of expensive equipment would have done.

I also take from it how useful it is to watch a full programme from the gallery before proposing anything. The cause was not where the team had been looking for months, and it only became visible when we sat through the whole broadcast and paid attention to how the picture changed between the first minute and the last.
