Three-dimensional image

The development of the Polaroid system of filming by American inventor Edwin Herbert Land made color 3-D movies a reality. Films made using this method are shot with two cameras or a special camera with two lenses. In the theater, the two films are projected simultaneously. A polarizing filter in front of the left projector lens orients random light waves into one plane, while a different filter in front of the right projector lens orients light waves into a perpendicular plane. Filmgoers wear glasses with gray polarizing lenses that orient light waves in the same way as the filters on the projectors. This causes the viewer’s left eye to see only the image from the left projector and the viewer’s right eye to see only the image from the right projector. The brain receives these two separate images and fuses them into one 3-D image. The first polarized film was demonstrated in 1939 at the New York World’s Fair. In the 1950s, attendance at polarized 3-D movies soared. Between 1952 and 1955, over 110 features, shorts, and cartoons were produced in 3-D. These included ; The classics House of Wax (1953) It Came From Outer Space (1953) Kiss Me, Kate (1953) Hondo (1953) Creature from the Black Lagoon (1954) Revenge of the Creature (1955). The 1950s also marked a high point for 3-D still images. In addition to films, 3-D images appeared ; comic books newspapers and magazines posters jigsaw puzzles greeting cards. The polarized film process lives on in today’s state-of-the-art 3-D movies in theme parks, as well as some IMAX 3-D theaters. IMAX 3-D movies project giant images on screens seven stories tall, giving viewers the impression that they are submersed in the scenes projected on the screen.
