ABSTRACT:
A fixed-focus camera provides flash photography of normal-range subjects beyond a near distance which is limited by depth of field and flash overexposure. A proximity sensor, in response to detecting that a subject to be photographed is closer than the near distance, causes an override mechanism to establish an exposure aperture which is smaller than the aperture normally set for flash photography. This reduces the near distance at which both depth of field and flash exposure are acceptable.
