ABSTRACT:
A background fill-lighting system for use in clinical portrait photography by dental health care personnel, and others, includes slaved fill-lighting of a concavely-shaped screen positionable behind the subject to be photographed. The slave lighting is mounted above or below the concave screen and is triggered by an electronic flash unit located on the camera. Resulting portraits have no distracting shadows on the background, while lens flare damage to resulting photographic images is eliminated.
