Popular Mechanics - August 1952


To increase the realism, the crew cut a canoe in half and mounted the big camera on a water-level platform

And what an answer it promises to be! The new movies, called Cinerama, are not stereoscopic. They don't have to be. The huge curved screen, more than three times as wide and half again as high as the standard theater screen, wraps the viewer in the center of the scene. The picture, projected from three booths, encompasses everything a normal person would see with his own eyes if he were standing where the camera was. Result-a three-dimensional illusion created by the viewer's own visual clues. And no one needs to wear the glasses that are needed  

for true stereoscopic projection.

To heighten realism, the Reeves Soundcraft Corp., owner of Cinerama, has added stereophonic, or "three dimensional," sound. If a person on the left side of the screen is talking, that's where the voice comes from. A gunshot on the right comes from that side. An airplane approaching from behind the audience roars overhead and its sound follows it as the image reaches the screen and zooms off toward the horizon far in the background.

Rear view of camera shows the unusual arrangement of reels made necessary by the use of three films
