In a system for exposing a photosensitive material to a video frame represented by a video signal, the image to be photographed is horizontally scanned by a line scanner and the horizontal line scan is incrementally advanced across the video frame in correspondence with the incremental advancement of an exposing focused line across the photosensitive material in order to fully expose the photosensitive material, one line at a time, to the image being scanned by the line scanner.
