Second variant of stereo camera provides for mark on boundary between frames of film ensuring its cutting. Third variant makes provision for indication of frame number applied on each frame of film. Fourth variant foresees mentioned mark and number. In devices for anchoring stereo slides pair of left and right film holders is joined together and mounted for sliding between bearing mount and cover mount, which have two frame windows. Device provides for identification mark to distinguish frames with odd and even numbers, which are applied on left and right frames. Left and right film holders can be simultaneously right and left film holders for even frames if turned through 180 deg.
