ABSTRACT:
There is described a system and method for reproducing an original record using a narrow band filter, such as a dichroic filter, to modify the contrast of the reproduction without modifying the color balance or the wavelength peak of sub-reocrds. The system is particularly useful in reproducing motion picture records where a multiplicity of additive lamp houses can be employed. The system reduces variations in contrast and color reproduction among different additive lamp houses.
