Abstract

An apparatus for photographing by using an electronic flash has a photography controller that carries out a pre-flash photography by emitting strobe light in a pre-flash exposure period and subsequently carries out a main flash photography by emitting strobe light; and an exposure adjuster that sets at least one exposure value associated with the pre-flash photography and/or the main flash photography. The exposure adjuster sets an aperture value of a diaphragm that suppresses an occurrence of saturation in image-pixel signals that are generated in an image sensor in the pre-flash exposure period. The photography controller drives the diaphragm in accordance to the set aperture value for the pre-flash photography.
