Kinemacolor was an additive process operated with alternating red and green filters that were applied to the shutter in front of the camera and in front of the projector. With at least 32 fps the frame rate was double the minimal frame rate of 16 fps. Time parallax with small differences between the red and green record resulted in color fringes that became visible when objects or scenes were moving.
The Kodachrome process was invented in 1913 by John G. Capstaff for still photography and subsequently adapted to motion pictures. For the process two frames were advanced simultaneously, one located above the other. The light passed either through two lenses or through a beam-splitter, fitted with red and green filters. The release print was exposed through a beam-splitter whereby the alternate frames were projected onto either side of double-coated stock. After development by a usual b/w process, the film was tanned to harden the exposed areas. The soft areas were dyed red-orange and blue-green respectively.
