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.
Claims11
A system for reproducing an original color record on a light sensitive material, the system comprising:
- (a) a color record having two or more sub-records with wavelength peaks in different regions of the electromagnetic spectrum;
- (b) an additive wavelength light source;
- (c) a light sensitive material onto which the color record can be illuminated by means of the light source;
- and
- (d) selective filtration means between the light source and the light sensitive material;
- wherein the selective filtration means modifies the contrast of the reproduction by means of off-peak energy filtration, without modifying color balance of the reproduction or the wavelength peaks of each of the sub-records.
A method for reproducing a color image, comprising the steps of:
- (a) providing a additive wavelength additive light source,
- (b) providing a color record having two or more sub-records with wavelength peaks in different regions of the electromagnetic spectrum;
- (c) providing a light sensitive material onto which the color record can be illuminated;
- (d) illuminating the color record onto the light sensitive material with the continuous wavelength light source;
- (e) selectively filtering from the additive wavelength light source one or more narrow bands of off-peak energy to modify the contrast of the reproduction without modifying the color balance of the reproduction or the wavelength peak of each of the sub-records.
