Lighting
More modern fixed Lens cameras with Digital Zoom are more susceptible to lighting issues, due to the smaller optics/Iris
Generally a good light colour temperature is 4000 kelvin, but consider increasing this number if you depend
mostly on daylight as your light source. A colour-rendering index (CRI) of 80 or better is important. Avoid
mixing technologies such as fluorescent and LED because their colour profiles differ.
Neutral Grey colours on walls and tables improve colour appearance.
Avoid completely white walls or tables, a colour with reflection value (LRV) of 50 percent is recommended.
Be aware that video is sensitive to high contrast levels in the room.
Most luminaries are made to avoid glare thus focusing the effect on the work area rather than people’s faces.
A common problem is insufficient light on people’s faces. A glare-free luminary producing directive light at an angle of 45 degrees is optimal for video, but may be challenging to achieve.
Following are some tips on how to improve the lighting situation within a room.
LED lighting may cause visible artifacts due to mismatch between framerate and LED frequency
Rooms should not have dimmer switches installed.
If a dimmer switch or panel is installed, there should be a preset light level to bring the room back to “meeting conditions”.
Electronic lighting ballasts that supply 20,000Hz or higher power to the lamp (instead of the mains frequency of 50-60Hz) are recommended. This prevents stroboscopic flicker associated with fluorescent lighting.
