ABSTRACT:
An apparatus for printing photographic prints has a negative exposing section, including a light source, an optical light filter system forming a beam of light along a path, a film transporting system for passing the negative film to be printed through the optical path of the light system, and a lens for projecting the virtual image to be printed onto the printing paper. A mirror is pivoted along one of its edges so that it can be raised into the light path to selectively reflect the light from the light source to a color analyzing system and optionally to a densitometer system. The color analysis system as positioned ahead of the negative printing station along the negative film transport path. The mirror is controlled to transmit light through the negative film when printing is taking place and to deflect all of the light to the color analysis and densitometer systems when printing is not taking place.
