ABSTRACT:
An exposure control apparatus of a camera includes a first switch which can select a plurality of drive modes including an auto-exposure bracket mode (AEB mode), a second switch which issues signals when operated, a third switch which can modify an exposure correcting value and a memory which stores a plurality of predetermined exposure correcting values. A drive mode selector successively selects the drive modes in response to signals from the second switch when the second switch is actuated during the operation of the first switch. A modifying device successively selects an exposure correcting value to be used to correct the exposure value among those stored in the memory in response to signals issued from the second switch when the latter is actuated during the operation of the third switch. A photographing controller is provided which takes a plurality of pictures at different exposure values in an exposure width correcting values selected by the modifying device when the AEB mode is selected.
