ABSTRACT:
In a camera system in which a shutter is opened and closed, a plurality of light sources are controlled to be energized serially following the opening of the shutter. The number of light sources to be energized is preset by the user, who also predetermines the length of time intervals between successive energizations. The sources can be caused to recycle for a predetermined number of times or to cycle only once. They can be arranged to flash immediately upon opening of the shutter, or to have an initial delay.
