When a sensitivity of film used for photographing is less than a predetermined sensitivity, or when an external light brightness measured by a photometry means is more than a predetermined brightness, a strobe exposure is controlled to decrease gradually from 0 EV flash, wherein a standard strobe exposure can be obtained, to -1 EV to -2 EV to -2 EV . . . . On the other hand, when the external light brightness is less than the predetermined brightness, the 0 EV flash is performed compulsively regardless of the film sensitivity, and the ratio of the strobe exposure becomes high, so that the exposure contribution rate of the external light is relatively lowered. As a result, the spectral characteristics of the external light source have small effect on the image surface when the high-sensitivity film is used, and the color fading caused by the spectral characteristics of the external light source can be prevented.
