Abstract
A camera includes an entry member which commands spotwise photometric means to effect the entry of spotwise brightness value or values of an object being photographed. A spotwise photometric mode is selected in response to a first operation of the entry member, and the entry of a spotwise brightness value or values occurs in response to a second and subsequent operation of the entry member. Spotwise brightness values and a result of an arithmetic operation performed thereon are nullified in response to the completion of a photographing operation in the spotwise photometric mode while maintaining the spotwise photometric mode. Exposure factors used when controlling an exposure by an automatic exposure control means are stored, thereby enabling a photographing operation or operations to be repeated under the same exposure level as that used during a previous photographing operation, by utilizing such exposure factors.
