The patent describes a shutter for use with a conventional camera using a rotary stepper servo motor as a drive means. The motor drives a first drum which in turn drives a second drum in order to advance a curtain attached thereto. This curtain has a plurality of slits therein which act as the shutter of the camera as they pass before the optical cone of the camera.
