This is the american most popular stereo camera. It uses the convenient 35 mm film. It is mostly intended to positive slides. Afterwards they must be mounted in carton frames and viewed in special devices. But of course you can shoot with negative film and enlarge stereo copies. One interesting thing about this camera is that the focusing system moves the film and not the lens !

If you want to see and learn more about stereos go to stereoscopy.com that is the source. I did not put any stereo of mine heat because I strongly recommend to do it live with real paper or ektas and not with a monitor. It is just a question of keeping the traditions.
