Mikut Color Separation Camera (1936)

Before Kodachrome, there was 3-color separation photography. This camera has beam-splitters and three mirrors in the back so it creates three images simulataneously through the single lens. Each image passes through a color filter (red, green and blue).

If you want to view the images in color, you use the Mikut Additive Projector which reverses the process (as long as you used reversal film so you have direct positives). The three exposures sit in the projector; each has a separate lamp and the proper color filter. Mirrors bring the three images together and they pass through the single projector lens onto the screen--and you got yourself a color slide.

Some time I'll scan the article that explains the whole system and upload it to the main website. It's amazing.
