Abstract

A method for a film recorder includes displaying a plurality of images on a modified liquid crystal display movably coupled to the film recorder, wherein the modified liquid crystal display panel comprises a liquid crystal display panel with only a single polarizing media layer, disposing a linearly polarizing filter in an optical path of the film recorder, orienting the linearly polarizing filter in a first orientation relative to the modified liquid crystal display panel to thereby configure the film recorder to receive the plurality of images as positive images, and orienting the linearly polarizing filter in a second orientation relative to the modified liquid crystal display panel to thereby configure the film recorder to receive the plurality of images as negative images.
