Abstract
A method and apparatus for adding titles, subtitles, and computer-generated images to pre-existing film images as part of the process of rephotography or photographic printing, in which a light valve is used first to create a high-contrast mask to prevent double exposure, and the same light valve is subsequently used to expose the image of the titles, subtitles, or computer-generated graphics onto the film.
