发明名称 METHOD OF CONTROLLING EXPOSURE IN PRINTING COLOR PHOTOGRAPH
摘要 PURPOSE:To obtain color balance by conforming the first function of values corresponding to an exposure quantity controlling value before changing the exposure quantity and a coefficient of weight for three primary colors or a specific visual sensitivity function to the second function made up of those values after change. CONSTITUTION:A negative film 1 is illuminated by a light source 3 through color-adjusting filters 2 of yellow, magenta and cyan, and transmitted light passes through a lens system 4 and a black shutter 5, and exposes a photographic paper 6 for printing. Developing, bleaching, fixing, washing and drying are made in a processing section 7. A light sensor 8 detects picture density of RGB, and the conditions of printing is determined by the detection signals. At this time, the exposure for three primary colors is made to full correction then lowered correction is made. At the same time, the exposure controlling value is corrected to make printing density by the two corrections equal to the specific visual sensitivity function.
