...filling the frame with a satisfying picture. Western art since the time of Pythagoras has sanctioned the esthetic mystery of "the Golden Section." Applied to a rectangle, the rule evolves a geometrical figure about five by three, or 1.61 to 1-almost exactly the proportion of the Paramount wide screen...

They can never be perfect reproductions of reality, but the margin between the original scene and the projected one has narrowed step by step. The new devices-3-D, wide screen, stereophonic sound-are further steps toward reality...
Binocular Cameras. Two camera lenses can approximate the two human eyes. They take two pictures of the scene from slightly different angles. Both pictures are thrown on the same screen, and the viewers are given means of seeing only one of them with each eye. The trick is worked with polarized light...
Ordinary light vibrates transversely (like shaking a rope) in all directions, but if it is passed through a Polaroid filter, it emerges with nearly all of its waves vibrating in the same direction. The two films exposed by the cameras are thrown on the same screen by two projectors. In front of one projector is a Polaroid filter that passes light with its waves vibrating, for example, vertically. In front of the other is a filter that passes light with horizontal vibrations. The viewers get glasses with lenses of Polaroid plastic. One lens passes light from the screen that...
Beyond the annoyance of glasses, this kind of 3-D has many faults, some of them incurable. Objects on the screen look solid, all right, but unless a viewer sits in a favorable part of the theater, they are distorted -either flattened or pulled out toward him.
