ABSTRACT:
A camera exposure mode setting device including a dial which can be moved to select a number of different exposure modes, one of which is controlled by a self-timer circuit in the camera. The device also includes circuitry coupled to the dial which operates to prevent the self-timer circuit from operating unless the dial is maintained in a self-timer exposure mode position. In a preferred embodiment, a push button extends from the dial, the button being arranged to prevent the dial from being moved to select the self-timer mode unless the button is first pushed down by the user.
