The early 1950's saw Hollywood

In September of 1922, the movie "Power of Love" was released. This film featured the "anaglyph process" which involved simultaneously shooting two view of a scene and then printing the film in two different colors and combining them with layered film on one reel. The moviegoer then viewed the film wearing a special pair of glasses with one red lens and one green lens. The red lens would draw the viewers attention to the green view of the scene and the green lens would draw the other eye towards the red view of the scene. This would cause an "overlap" which made certain objects appear closer than they were and others seem to move out of the screen towards the viewer.
