ABSTRACT:
A pair of masks are mounted in front of a camera lens, one mask adjacent the lens and the other an adjustable distance in front of the first mask. The masks permit light to be transmitted through only a predetermined portion of the lens during each exposure so that only a corresponding portion of the film frame is exposed. The distance between the outer mask and the lens is adjusted according to the focused position of the lens when a zoom lens is employed to obviate overlapping of adjacent images on the film. The mask adjacent the lens opening is used with a conventional lens for forming four exposures in different areas of a single film frame.
