A New Color Intermediate Positive—Intermediate Negative Film System for Color Motion-Picture Photography

A new color film, Eastman Color Intermediate Film, Types 5253 (35mm) and 7253 (16mm), which is designed for making intermediate color positives and duplicate color negatives from Eastman Color Negatives, is described. The convenience of a single color material for the two intermediate stages is noted, and the application of this film to the preparation of reduced-size duplicate negatives for contact release printing is discussed. — The need for sensitometric control in the printing and processing operations is stressed, since this all-color system does not have the contrast adjustment available when three silver-image separation positives are used. Processing and printing instructions are given, and a method for prevention of Newton's rings during contact-printing is described. The effect of inadequately exposed duplicate negatives on tone reproduction is pointed out and a method of determining optimum exposure is discussed. Several applications of this new film to motion-picture production are mentioned.
