The color nega/paper system has been widely used by amateurs and professional studio photographers. The present article analyzes the tone reproduction in the color nega/paper system to know how much information recorded on the negative film can be transferred onto the final print. The current nega/paper system for amateur use is designed so that it can favorably reproduce the information of interest on the print with a reasonable cost and a quick processing, sometimes with a certain loss of gradational information recorded in the film. The one for professional use, on the other hand, is designed to focus on a more faithful tone reproduction with a far reduced loss of information recorded in the film. Further, our analysis on the lightness distribution in some practical scenes indicates that professional photographers have a good command of their shooting techniques to make a full use of the potentials of sensitized products used.
