Start with the shot, not the fixtures
Before anyone opens a catalogue, write down the shots the desk has to deliver. A single presenter on a wide two-shot needs a different spread of light from a three-person panel with a guest sitting off to one side. Sketch the desk from above, mark each camera position, and note which shots are tight and which are wide. This sketch is the document every later decision refers back to, so keep it simple and keep it on paper where the whole crew can mark it up during rehearsal.
Next, note the ceiling height and the grid or rigging points you actually have. Many smaller studios assume they can hang anything anywhere and then discover a fixing that cannot carry the load, or a beam that sits exactly where a backlight should be. Measure the throw distance from each planned position to the presenter's face. Distance decides how much output you need and how hard or soft the light lands, and getting it wrong means swapping fixtures after the rig is already up.
Finally, agree the look in plain words with the producer: bright and open for a morning bulletin, a little warmer for an evening programme, or something more contrasty for a late discussion. Words like these feel vague, yet they save an hour of argument later. Record the agreed description at the top of the plan so that whoever relights the set months from now can read the intent and not just the fixture list.
- Sketch the desk from above with camera positions
- List the tightest and widest shots required
- Measure ceiling height and throw distances
- Write the agreed look in two plain sentences
Build the key, fill and back light in that order
Place the key light first, because everything else is judged against it. For a seated presenter, aim for a soft source slightly above eye level and about thirty to forty-five degrees off the camera axis. Diffusion matters more than raw power here: a larger, softer source flatters faces and forgives small movements, while a hard source punishes every shift in posture. Check the result on the camera monitor, not by eye, since the lens and sensor will show you shadows the room hides.
Add fill only as far as the key requires. The aim is to hold the shadow side of the face at a comfortable level for the style you agreed, not to flatten it entirely. Studios often over-fill because it feels safe, and the picture then loses shape and looks like a flat office video. Bring the fill up slowly, watching the waveform or a reference monitor, and stop as soon as the shadow detail reads clearly without looking lit from the front.
The backlight separates the presenter from the set behind them. Set it behind and above, aimed at the shoulders and hair, and keep it modest. A strong backlight on a presenter with pale hair or a shiny jacket can burn out quickly. Cross-check from each camera angle, because a backlight that works for the front camera may throw a distracting flare into the side camera's lens.
Balance the set behind the desk
Once faces look right, turn to the background. The set should sit a little below the presenters in brightness, so the eye goes to the people speaking. Light the backdrop separately from the talent, using fixtures that can be dimmed independently, so that a change to the desk never forces you to touch the wall behind it. Where the set includes screens, keep their output in mind: a bright video wall can overpower everything else if it is not accounted for in the plan.
Watch for shadows thrown onto the backdrop by the desk lighting. A presenter leaning forward can cast a hard shadow across a set piece, and it is the sort of detail that only appears once a real person sits in the chair. Walk a stand-in through the likely movements during the first rehearsal, and mark any problem spots on the plan. Moving a fixture by half a metre at this stage costs minutes, while fixing it after a live broadcast starts is not an option.
Colour consistency across the set deserves its own check. Mixing fixtures with different colour temperatures, or leaving daylight spilling in from a window, produces patches of warmer and cooler tone that the camera exaggerates. Cover or block the windows where you can, and keep all main fixtures to a single colour temperature so that white balance holds across every camera.
- Dim the backdrop on its own circuit
- Keep set brightness slightly below talent
- Check for desk shadows with a stand-in
- Hold one colour temperature across fixtures
Count the power before you count the lamps
A plan that looks fine on paper can trip a breaker on the first day. Add up the wattage of every fixture you intend to run at once, then compare it with the circuits actually available in the studio. Remember that the studio's sockets may share a circuit with the gallery, the monitors or the air conditioning, which means the real headroom is smaller than the number printed on the distribution board. Ask whoever maintains the building for the circuit layout before you finalise the rig.
LED fixtures have eased this problem considerably, but they bring their own considerations. Dimming electronics, power supplies and cable runs all add up, and a long chain of fixtures on a single cable can introduce voltage drop that shows as flicker or uneven output. Split large rigs across several circuits and label each cable run at both ends, so the crew can trace a fault in seconds rather than minutes.
Leave a margin of at least twenty per cent unused. A rig that runs at the limit of its supply has no room for the extra light a guest with dark skin or a bright jacket may need, nor for a fixture added on the day. A margin also reduces heat in the cabling and keeps the whole installation easier on the equipment over the years it will be in use.
Plan for the crew's time, not just the picture
A good rig is one a small crew can set, adjust and strike without drama. Mark fixture positions on the grid or floor with tape or paint, so that the same layout can be recreated after a one-off event takes over the studio. Photograph the finished rig from the camera positions and keep the images with the plan. When someone new joins the crew, these records turn a half-day of guessing into a short, confident setup.
Think about access as well. If every adjustment needs a tall ladder or a lift, fixtures will go unadjusted, and the look will drift. Where possible, choose fixtures that can be pole-operated or controlled remotely, especially those you will need to tweak between segments. A few minutes saved on each change adds up across a week of live programmes, and it keeps the crew's attention on the show.
Build a short pre-show routine into the plan: switch on, check every fixture is live, confirm the colour temperature, and view each camera. Writing it down as a five-line checklist sounds trivial, yet it catches the dead lamp or the knocked fixture before the presenter is seated. The crew that follows a routine rather than relying on memory is the crew that rarely has a surprise at the start of a broadcast.
- Mark fixture positions on the grid or floor
- Photograph the rig from each camera position
- Choose reachable or remotely controlled fixtures
- Keep a five-line pre-show check beside the plan
Test under rehearsal conditions and write it down
The plan is only a hypothesis until it is tested with real people, real clothing and the cameras you will use. Run a full rehearsal with the presenters in the clothes they usually wear, and watch the pictures on a calibrated monitor. Pay attention to shiny surfaces, glasses, jewellery and any reflective item on the set. Small adjustments to angle or height at this point often solve problems that no amount of paperwork would have predicted.
Record every change you make during the test, with the reason. A note such as 'key lowered ten centimetres to remove glasses reflection' is worth far more to the next person than a general comment that the rig was adjusted. These notes form the living record of the studio's lighting, and they allow anyone to restore the setup after a change or repair without starting from nothing.
Revisit the rig after the first few weeks of use. Habits settle, presenters sit slightly differently from how you expected, and the crew finds shortcuts that deserve to be written into the plan. A short review, with the producer and the person who operates the lights most often, keeps the design honest and the look consistent through the darker months when the studio is busiest.
A good news desk rig comes from a handful of simple habits: begin with the shots, build the key before the fill, light the set separately, respect the power supply and design for the people who will run it. Keep the plan on paper, test it with real presenters, and write down every change. Done this way, lighting becomes a stable part of the studio's routine, and the crew can spend their time on the programme.
