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.
Claims7
Apparatus for use in composite photography comprising the combination of:
- a motion picture camera having a lens and a length of film for recording images thereon via said lens;
- a beam splitting means carried on said camera and having optical elements substantially lying along the optical axis of said lens;
- a background means in spaced relationship to said camera and disposed behind a subject intended to be recorded on said film;
- and
- said optical elements including a beam splitting element for optically dividing an image of said subject into a pair of identical images and further including filter elements for modifying said pair of images so that each image and background therefor is reversed when recorded on said length of film.
