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-records. The system is particularly useful in reproducing motion picture records using subtractive lamp houses so as to have their contrast and color reproduction match records generated using additive lamp houses.
