Abstract
A camera back for sequentially exposing two spatially separate images on regular or self-developing film adapted for a variety of single lens cameras. The camera back includes an adapter plate disposed between the camera and a film back wherein a dark slide is movable by the force of gravity between two positions in the adapter plate, by rotating the adapter plate 180 degrees, thereby blocking a lower half of the film from the exposing radiation. The dark slide is moved exclusively by its own weight, thereby making complicated levers and light-tight feedthroughs unnecessary.
