ABSTRACT:
A method of making a high quality three-dimensional photograph is disclosed. The method utilizes a camera with a film mount therein, a rastor, a film, a separator for keeping the line rastor separate from the film, and a vacuum generating device for maintaining a vacuum in the vicinity of the separator thereby bringing the film into intimate contact with the separator and maintaining the intimate contact through successive exposures and movements of the film and line rastor. After repeated exposure of the film in various positions with respect to the subject being photographed, the film and rastor are laminated to opposing sides of the separator and the resulting photograph is viewed from the rastor-carrying side of the photograph by means of a light source and diffusion screen on the film-carrying side of the photograph.
