ABSTRACT:
Color film which has relatively high photographic sensitivity, improved spatial sensitivity and reduced problems with aliasing between film stripe structure and scene content and from which full color photographic information can be extracted. An embodiment of the color film includes a black and white photographic film emulsion which is coated upon a substrate, which emulsion is covered with a repetitive pattern of a triad of: (a) color stripes such as yellow, green and cyan stripes wherein at least one of the colors is a nonprimary color; (b) color stripes of unsaturated hues such as, for example, pastel yellow, pastel green and pastel cyan stripes wherein at least one of the colors is a nonprimary unsaturated hue; or (c) color stripes of unsaturated hues of any color. Full color prints or enlargements are made by a hybrid process which includes electronic scanning to extract color information and an optical or an electronic method to extract detail information.
