Max Otto Miller was an American film producer and inventor of the Miller Stereoscopic Process.[1] [2] It was an early 3-D process of making and projecting pictures, using a conventional camera lens with a concave spherical lens attached to increase field without increasing object distance. It included a special design for the aperture plate and projection of the picture through a double convexed spherical lens of lesser focal length. The method used 35 mm film printed single strip anaglyphic.[3] It was used in films including the 1925 silent western The Ship of Souls.[4] Miller also produced the 1924 film A Pair of Hellions. His son was director and photographer Max B. Miller.[5]
