The position of a principal image within a frame is designated manually or in association with the operation of the automatic focussing mechanism. The position information of the principal image is recorded on a photographic film when a subject is photographed. In obtaining a photoprint, the position information is read from the frame to be printed, and the principal image within the frame is identified. A characteristic value used for calculating an exposure amount is derived from the identified principal image, so as to execute an exposure control emphasizing the principal image.
