Lighting and control

Lighting people for camera

Prepare key light, fill and background separation for the framing, movement and camera.

Ask GLMedia about a lighting rental solution for your event, subject to availability and technical requirements.

Using this guide

This guide proposes a preparation sequence for interviews, panels and presentations. Fixture count depends on coverage and shots; it cannot be inferred from camera count.

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.
Visual goal and problem to solve; venue plan or identified photos if available.
Decisions already agreed with venue, production and video to assess a suitable solution.

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

Keep key, fill and background on identifiable controls. Decorative RGB wash does not guarantee suitable skin rendering; compare results with the actual fixture and camera.

Prepare the system

Define framing, talent marks and movement. Review windows and existing light at event time; agree on white balance and exposure with video.
Set the key and check eyes, nose shadows, glasses and clothing. Try compatible diffusion or bounce and re-aim before adding power; check reach and output loss.
Add fill and backlight for the shot. Secure supports, accessories and cables; verify label power, DMX mode, patch and a saved recovery state.

Questions and troubleshooting

Does skin look green or different across cameras?

Isolate sources and compare using common camera settings before correcting the whole show.

Record white balance, tint and exposure; observe a neutral reference and the person under each source separately.
Try fixture correction only when supported by that model. Matching color-temperature values does not prove matching spectra or skin rendering.

Are eyes dark or glasses reflecting the light?

Geometry can cause the problem even with sufficient light.

With the person in position, change key height and direction and check each camera. Avoid dazzling talent while adjusting.
Add controlled fill if needed and repeat with head turns. Save positions and levels that work for the agreed shots.

Does the LED wall look washed out or overpower the face?

Test lighting and content together with the video team.

Limit spill using methods supported by the optics. Check that front light does not unnecessarily illuminate the wall.
Compare faces and bright/dark content on camera. Coordinate light, brightness and exposure adjustments; do not blindly add frontal power.

Precautions

Do not prescribe universal lux: agree on a target for project sensitivity, lens, distance and exposure.
Use compatible accessories and manual-approved attachments; do not cover ventilation or improvise fabric over hot fixtures.
Rehearse every shot and the full movement area; record settings and any flicker at the actual dimmer level.
