Abstract
A bracketing exposure control camera having a total exposure shift range calculated based on the number of frames and the exposure shift amount. If the total exposure shift range overflows a predetermined exposure shift range, then the number of frames and/or the exposure shift amount is adjusted to maintain the adjusted total exposure shift range within the predetermined exposure shift range.
