Interimage Effects and the MTF of a Color Reversal Film

摘要

Interimage effects have long been recognized as a factor in the reproduction of color. Reversal materials are no exception and exhibit interimage effects which have previously been revealed through techniques using END analysis. This study presents a method for revealing the presence of interimage effects in a reversal film's Modulation Transfer Function. Utilizing filtering techniques, two dyes of a three color transparency are eliminated from the final image by exposure and development. The remaining single dye image at a specified level is then compared to the corresponding layer and image in a colorimetrically specified neutral. The edge gradient analysis method is used to calculate the Modulation Transfer Functions. MTF results indicate the desirability of using colorimetry for the specification of a visual neutral. MTF values are indicative of a significant effect on the Modulation Transfer Function by interimage effects. (Author)
