Abstract: The present invention covers automatic and manual control of the color of light striking film in a camera by electrically manipulating the color purity of one or more optical color correction filter elements made of clear and dyed dichroic liquid crystals that do not significantly disperse light being transmitted through the filters. In a preferred embodiment for a camera the opto-electrical and electrical components of the invention are designed to provide automatic correction of incident light on a photographic subject to match the color temperature standard to which the film was manufactured.
