ABSTRACT:
A photographic camera with a pseudo-telephoto mode of operation, a flash unit, and a picture taking lens that can be set at a plurality of focal lengths includes a controller that responds to a low-light condition by activating the flash unit, positioning the picture taking lens at a reduced available lens focal length than that selected by the user, and by placing the camera in a pseudo-telephoto mode, in which a frame image from the picture taking lens is designated as a pseudo-telephoto frame. The reduced focal length provides a lens setting with increased light-gathering ability. The focal length selected by the controller can provide a print that, in combination with pseudo-telephoto processing, will provide a print with a relative magnification approximately equal to a print that otherwise would be provided from the lens focal length setting initially selected by the camera user.
