Lighting and control
Lighting a presenter with camera and LED wall
Prepare face light, movement and LED background through joint lighting and video checks.
Ask GLMedia about a lighting rental solution for your event, subject to availability and technical requirements.
Using this guide
Define the wide shot and close-ups before positioning lights. Wall and presenter need separate controls.
Prepare your rental inquiry
- Date, city, venue and setup, event and pickup schedule.
- Intended use, area dimensions and equipment already supplied by the venue or production.
- Presenter movement, camera positions and intended shots; screen location and approximate space dimensions.
- Approximate LED size, examples of bright and dark content, and the video lead’s contact. Include camera and processor details if known; a complete technical specification is not required to start an inquiry.
Specify equipment only or whether setup, programming, operation and strike are also needed. Scope is confirmed in the proposal.
You do not need a final equipment list: tell us the result you want and the part you need help with. Availability and scope are confirmed in the proposal.
Features and connections
Front light must cover the agreed movement; shaping and aiming help protect background contrast. Screen timing and fixture flicker require separate diagnosis.
Choose coverage around the agreed movement and shots: a fixed position allows a focused setup, while a walking presenter needs consistent facial visibility across the area. Agree on those boundaries with video before finalizing the proposal.
Prepare the system
- Mark positions, heights and movement; agree on camera, exposure, white balance and test content with video.
- Test key, fill and backlight with a person, actual clothing and glasses. Check transitions between zones from every camera.
- Save stable front light and record agreed screen settings; confirm who controls each system.
Seated panel in front of an LED wall: check every seat
A panel creates a different coverage problem: a guest may turn toward the moderator and fall into shadow even when the wide shot looks even. Mark seats, table, microphones and conversation directions on a sketch, along with entrance and exit paths.
- Place a stand-in in each seat, looking forward and to both sides. Check nose, glasses, tabletop and microphone shadows in the wide shot and each close-up. Do not raise the entire front wash to fix one dark seat.
- Compare shared cross-light and fill with tighter individual seating zones where suitable mounting positions exist. Shared coverage accommodates movement; individual zones can contain spill but require another check of overlaps and seat changes.
- With the video team, show the planned bright and dark content to the cameras. Record the agreed lighting state and assess faces and wall together. Repeat the affected test if content or seating changes.
GLMedia can evaluate fixture and accessory rental, installation, adjustment and operation for fixed seating or a more flexible panel area. Send the date, venue, participant count, a photo, approximate dimensions, possible light and camera locations, and who supplies the wall. You can start discussing alternatives before models are known; equipment, availability and scope require confirmation.
Questions and troubleshooting
Does the face become dark while walking?
Look for coverage gaps and level differences between zones.
- Walk the area while recording the planned shots; check edges and beam overlap.
- Re-aim and balance before adding fixtures. Repeat with the presenter looking both ways.
Does the LED force overexposure of the face?
Assess face and background within the same shot.
- Display bright and dark event content and check the signal with video; do not copy a brightness percentage from another venue.
- Limit front-light spill onto the wall with compatible shaping and coordinate brightness/exposure while retaining audience readability.
Do bands or patterns appear in recordings?
Identify whether the defect comes from lighting, the LED or its interaction with camera. Distinguish bands related to synchronization or shutter timing from spatial moiré between the LED pixel grid and the camera sensor. For moiré, test framing, distances and focus with video, including the planned camera moves. No universal distance or setting guarantees its elimination.
- Test each system separately and record shutter, frequency, level and shot that reproduce it.
- Video should check processing, sync and supported LED settings. ShutterSync is specific to compatible systems, not a universal option.
Precautions
- Do not promise minimum distance, lux or freedom from moiré without testing the actual camera, lens, screen and framing.
- Keep supports and cables outside movement; suspend only with documented attachments and secondary retention.
- Rehearse control loss with an agreed recovery state; do not improvise network or firmware changes during the show.
