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.
Apparatus for series photography of a subject in motion, said apparatus being adapted to be associated with a "still" camera, a field stop defining an aperture sized and positioned to effectively reduce the total field of view of the associated camera, means mounting said field stop in front of said associated camera for movements in all directions in the general plane of said field stop, means for displacing said field stop to follow displacements of the subject in motion, and means for adjusting the shape and/or size of aperture of said field stop.
Apparatus for series photography of a subject in motion, said apparatus being adapted to be associated with a "still" camera and comprising a base, means on said base for mounting a still camera, a field stop defining an aperture sized and positioned to effectively reduce the total field of view of the associated camera, means mounting said field stop in front of said means for mounting the associated camera for movements in all directions in the general plane of said field stop, means for displacing said field stop to follow displacements of the subject in motion, and means for manually controlling a shutter release mechanism of the associated camera.
A camera accessory for series photography of a subject in motion, said camera accessory being adapted to be associated with a conventional "still" camera and comprising a base, means on said base for mounting the still camera, a field stop defining an aperture sized and positioned to effectively reduce the total field of view of the associated camera, means mounting said field stop on said base in front of said means for mounting the associated camera for movements in all directions in the general plane of said field stop, and means mounted on said base for displacing said field stop, to follow displacements of the subject in motion.
Apparatus for series photography of a subject in motion, said apparatus being adapted to be associated with a "still" camera and comprising a base, means on said base for mounting a still camera, a field stop defining an aperture sized and positioned to effectively reduce the total field of view of the associated camera, means mounting said field stop in front of said means for mounting the associated camera for movements in all directions in the general plane of said field stop, and means for displacing said field stop to follow displacements of the subject in motion with a plurality of discrete portions of a frame of a film corresponding to the size of the predetermined field stop aperture being exposeable to photograph the subject in motion in a series of positions along its path of displacement.
