ABSTRACT:
A method and apparatus for series photography using a "still" camera for taking a series of discrete shots on a single frame of film of the subject in motion relative to the camera. A field stop is mounted on a base in front of the camera lens, the distance from the camera and the size of the aperture in the field stop being such that it reduces the effective total field of view of the camera to a portion thereof. The field stop is mounted for displacements in all directions in its plane. An operating member permits the operator to displace the field stop continuously following the displacement of the subject in motion, for example, by means of a movable finder mark mounted on the operating member for movement with respect to a viewfinder frame fixed on the base. In one embodiment the shutter of the camera is employed and in another an additional shutter is mounted between the lens of the camera and the field stop. In the former embodiment various means are disclosed for controlling the shutter release mechanism of the camera in order to effectively automatically follow the subject in motion.
