ABSTRACT:
This invention relates to the process of producing an inherently color biased image composition. More specifically, the invention is concerned with identifying the inherent color bias characteristics of an image, so that the image density variation from the image production system targeted density can be compensated by including a complementary color zone to be included in the computation by an image analyzer, thereby automatically achieving optimum color balance in the projected image. Another aspect of the invention relates to the process of producing color images using color panel(s), being concerned with a method of visual identification of an absence or an additional presence of a hue that tilt the color balance on a hue sensitive color panel. These methods are apt for color photographic prints control as well as for any color image production systems working on similar color production principles.
