ABSTRACT:
An artificial illumination control system for controlling the energization of an electronic flash device during a photographic exposure interval in a camera has three flash related modes of operation, full flash, no flash, and fill flash, one of which is automatically selected in accordance with the level of ambient light intensity. If, however, the level of ambient light intensity warrants the fill flash mode, but the camera-to-subject distance exceeds a predetermined distance beyond which the flash output may be ineffectual for a fill flash exposure, the fill flash mode is prevented and the control system reverts to its no flash mode.
