RODUCTION OF STEREOSCOPIC PICTURES

摘要

A photographic camera for three dimensional photography on fixedly positioned photosensitive material. A screen having a plurality of lenticular elements with the boundaries of adjacent elements forming lines defining stripe portions is located in the light path from the object to be photographed and positioned closely adjacent to and in a fixed relationship to the surface of the photosensitive material. A shutter having a substantially rectangular aperture interrupts light passing through an objective, the screen and onto the photosensitive material. The objective's effective aperture defined by parallel planes at opposite sides of the optical axis and transverse to the stripe portions enables a reversed image to be produced on the photosensitive material by a single exposure. The reversed three dimensional original image upon development is positioned closely adjacent fresh photosensitive material. A lenticular screen having substantially the same optical characteristics as that used in the camera is positioned in the light path immediately adjacent a side of the original which is opposite from the fresh photosensitive material. At least two of the elements including screen, original photosensitive material and beam of light are moved relative to at least two elements and moved relative to the remaining elements to create a non-reversed three dimension image on the fresh photosensitive material.
