ABSTRACT:
A flash shot control device for a camera in which the angle of flash lighting is controlled in accordance with the output of a backlight detector. On assumption that a subject of principal photographic interest takes its place at the center of the field of view, when backlight is detected, the flash lighting is concentrated to the central portion of the field of view, thereby the shadows of the subject are lightened by the flash.
