Abstract
An imaging apparatus that uses luminance information obtained through a test flash by a flash unit for illuminating a subject to determine a flash quantity of a flash unit for main photographing sets exposure conditions for the test flash based on exposure conditions for the main photographing. The imaging apparatus changes a predetermined test flash quantity for the test flash to compensate a difference between the set exposure conditions and predetermined initial values of exposure conditions for the test flash and performs the test flash based on the set exposure conditions and the changed test flash quantity.
