  • Patent number: 4083059
    Abstract: In a camera provided with a day-light exposure range and with a flash exposure range, an automatic exposure control system for controlling the iris of the camera in accordance with a computed exposure value and a preselected shutter time is associated with a flash exposure time range bracketing device in order to insure that the formation of a correct flash exposure aperture is effected with automatic selection of one of the bracketed exposure times despite an accidentally incorrect setting of the shutter dial of the camera which may be encountered particularly when the day-light exposure range is to be left for the flash exposure range without the necessary manipulation of the shutter dial therefor.
