Abstract
Duplicates of positives or negatives can be made by the familiar process of exposure, standard development, and fixation of a single film without requiring second exposure and development, as in the case of amateur motion picture reversible film, or resort to the duplicate negative process. Contact printing is required with exposures about equal to those used in printing chloride photographic paper emulsions. The emulsion, although of silver bromide composition, is of a type entirely different from all other photographic emulsions, making use of the solarization effect for the first time in practical photography. Some commercial possibilities of the new type of emulsion are seen in the duplication of x-ray and other valuable transparency originals, aerial mapping, motion picture still picture printing, photo reproduction practice, and general commercial photography.
