ABSTRACT:
Apparatus and method is disclosed herein for producing a pair of identical images on the same piece of film except for the appearance of the background which becomes black behind one of the images and clear behind the other. The apparatus includes a background screen reflecting polarized light and a motion picture camera having an image duplicating device carried before the lens thereof comprising a beam split element for optically conducting a pair of images simultaneously through filters via front surface mirrors and prisms to a recording film strip. One filter is of neutral density so that a half frame on the film strip records a black image on a clear background while the other filter is a polarizing filter producing a clear image on a black background on the other half of the film strip frame.
