A High-Speed Black-and-White Negative Film

The new camera film, Eastman Double-X Panchromatic Negative Film, Types 5222 (35mm) and 7222 (16mm), has been designed to give more than twice the speed of Eastman Plus-X Panchromatic Negative Film (Type B), Types 4231 (35mm) and 7231 (16mm), without a significant increase in graininess of prints made therefrom. This permits exposures under adverse lighting conditions, or with increased depth of field without an increase in illumination, or with greater economy in set lighting. The new film will find wide application for general motion-picture work and television use. Processing and printing procedures are compatible with those used for Types 4231 and 7231. The characteristics of the film which affect picture quality are discussed.
