Abstract

A transparency viewing device including a faceplate adapted for mounting at least one transparency having a particular density at a portion thereof, a source of back illumination for the transparency and a controller which varies the chromaticity of the back illumination based on the particular density. Preferably, the controller varies the chromaticity based on the chromaticity of the transparency. Additionally or alternatively, the controller locally varies the chromaticity.
