Abstract: A CRT apparatus for illuminating color photographic negatives to faithfully produce colored hard copies in photographic printers without the use of dark shutters, heat shields and/or moving color filters. The preferred embodiment of the present invention employs an ordinary color television with a R, G, B input, driven by a signal controller and a specially designed CRT. The controller previews and analyzes the negative with inputs from an ordinary color television camera illuminated by a standard light source. A sample of the recording media for the hard copy, which was exposed to a pattern generated by the controller and displayed on the CRT, acts as a standard reference for the controller's mathematical manipulations to analyze the hard copy media sample, and control the Kelvin temperature and luminance settings of the CRT when exposing the hard copy through the subject negative in order to achieve automatic color balance in the hard copy.

Abstract: A microprocessor controlled camera system for exposing film with a photographic subject, a field of bar code data relevant to the subject and a field of data taken from a written card. The camera system includes an elevator assembly for raising and lowering the camera in response to a control actuator and a fixed aperture dual zoom lens system for framing the subject under control of the control actuator. A flash control system utilizes reflected light from the flashtube to indicate the amount of additional light needed on the subject and commands additional energy storage capacitors to be discharged through the flashtube to increase the subject illumination to a desired level.
