Abstract:
1. A camera controlling a main flash device and a remote flash device to perform multiple flash photographing, the main flash device illuminating a subject and emitting a preflash prior to a main flash, the remote flash device illuminating the subject from a position different from a position of the main flash device and emitting a preflash prior to a main flash, the camera comprising: a photometry section outputting a photometric value of each of a plurality of divided photometric regions that are formed by dividing a field; a provisional flash amount calculating section calculating a provisional expected light amount of the main flash device based on the photometric value that is obtained by said photometry section at the time the main flash device pre-flashes, and calculating a provisional expected light amount of the remote flash device based on the photometric value that is obtained by said photometry section at the time the remote flash device pre-flashes; and a main flash amount calculating section summing up the provisional expected light amounts of the main and remote flash devices to calculate an expected illumination amount for each of the divided photometric regions; judging whether or not there is an over-illuminated region, among the divided photometric regions, in which the expected illumination amount exceeds a proper illumination amount; and if a result of the judgment is positive, calculating expected light amounts of the main flashes of the main and remote flash devices by decreasing the provisional expected light amounts of the main and remote flash devices, the decreasing being done such that of the two flash devices, the one illuminating the over-illuminated region more is given a larger decrease, and that the expected illumination amount for the over-illuminated region is to be the proper illumination amount.
