Abstract
Silver chloride color negative films can be rapidly processed using shortened color development times and specific amounts of color developing agent and bromide ion. After development, and optionally desilvering or fixing, the developed film is scanned to form density representative digital signals for the color records. These signals are then digitally manipulated to correct both interimage interactions and gamma mismatches around the color records to produce a digital record that is capable of providing a display image having desired aim color and tone scale reproduction. That digital record can then be stored or used to provide corrected display images, such as color prints, using output display devices.
