Abstract
A negative density range control system uses color hue contrast to provide a print of a picture, by comparing the relationship between negative hue density and print emulsion density requirement and providing an appropriate density for a printing process, whether converting a positive digital image to negative digital image with a specific hue density color or making a print by contact printing a hue density negative rendered from a digital image file.
