There are several components that go into designing an optimal collaboration: space, displays, speakers, microphones, video switching, control systems, the list goes on. But what about the lighting; how does it fit into the mix? Believe it or not, room lighting plays a dramatic role in the image quality being displayed to remote conference participants.
Amount of Light:
Remember, there is such a thing as too much light. Meeting participants do not want to feel like they stepped into an operating room any more than stepping into a romantic restaurant. In addition to being uncomfortable for local participants, too much light can leave remote participants communicating with washed out, ghost-like figures. Conversely, not enough light can cause dark shadows and possibly distorted images for remote viewers. Finding the perfect balance of lights is imperative for displaying crisp, clear images over video.
Direct vs. Indirect Light:
Simply put, direct lighting is where camera can see a hotspot or the light causes sharp shadows or highlights, is directed toward the participants. Indirect lighting will fill or flood the space with light, prevents excessive brightness or contrast and prevents casting shadows on the participants. Indirect lighting is often configured with reflectors that direct the light toward participants faces creating a more natural appearance by defining facial features.
While indirect lighting simulates a more natural view, it can be problematic when projected displays are used in the video conferencing environment as it may put too much light on the display if not configured correctly. In these instances more controlled, direct lighting fixtures should be used.
- All lamps should be changed at the same time for even light color distribution and to maintain consistency
- Down can lighting should be avoided as it causes shadows on participants’ faces.
- Recessed lighting on walls within camera view can help differentiate between the participant and the background.
- Use neutral non-white wall colors, such as light blues or grays, with a satin or flat finish to disperse the light evenly.
- If there are windows in the background use vertical blinds over horizontal blinds as they have a lesser effect on the transmitted camera image.
