a method of obtaining a stereoscopic (three-dimensional) picture by means of two original black-and-white pictures of the same object that are tinted different colors or projected onto a screen through filters of the proper colors. The three-dimensional perception is caused by the fact that the pictures making up the stereoscopic pair, which were photographed with a certain distance between the optical axes of the lenses (photographic basis) and then are superimposed on one another with a certain parallax, are seen by the observer (through glasses of various colors) in varying perspective. If, for example, a picture designed to be viewed with the right eye is tinted red and a picture for the left eye is tinted blue-green, the observer must use glasses with different-colored lenses: blue-green for the right eye and red for the left eye. As a result of this, each eye will see only “its own” picture, which appears gray. These two separate gray pictures are perceived by humans as one three-dimensional black-and-white picture. In order to improve the conditions for observation of variously colored pictures and to achieve an identical perception by the eyes of the gray color of each picture, complementary colors are used. The anaglyphic method is used to create three-dimensional models of locales, to obtain three-dimensional illustrations in teaching aids for stereometry and descriptive geometry, and to obtain stereoscopic motion pictures.
