Put light near the camera path
The camera needs the face lit, not just the room. Start with a small light near or above the camera and reduce strong backlight from windows.
Check glasses and glossy screens
If the light appears as a white spot in glasses or the monitor, lower brightness, move it sideways, or raise the angle until the reflection leaves the camera view.
Separate call lighting from task lighting
A monitor bar can make typing easier while a camera light makes the face clearer. Some desks need both, but each solves a different job.
Save a repeatable meeting preset
Use the same brightness, color temperature, camera height, and chair position for recurring calls so setup friction does not make the light go unused.
