Abstract
A camera capable of restarting the bracketing exposure mode even after all the frames of a film have been exposed during the bracketing exposure mode. An output derived from detector for detecting the trailing end of a film is delivered to controller which controls the arithmetic operation for obtaining an optimum exposure value as well as the bracketing exposure so that in response to the above-stated output, the controller inhibits the shutter release after the end of the film, but maintains the bracketing exposure mode. Furthermore, the remaining exposures of a predetermined number of exposures in the bracketing exposure mode are cancelled at the end of the film.
