Abstract
A method and apparatus for creating traveling mattes in which a first image is photographed and then sensed. The first image is then electronically processed followed by the steps of photographing on the same film a successive image and simultaneously transmitting to a light valve an electronic signal to produce a high-contrast negative image corresponding to the first image so that the successive image is combined with the first image.
