Ultra‐fine‐grained, high‐contrast 35mm photomicrography using high contrast copy film

Abstract

Ultra‐fine‐grained, high‐contrast prints that have a limited but usable tonal range can be obtained from Kodak High Contrast Copy film¹. Using this film, exposures are made at an ASA of 6, and the film is developed in normal developer concentration for 85 seconds, then transferred to a water bath for 5 minutes 5 seconds. The method is presented as a means of obtaining high‐quality photomicrographs with a minimum expendition of time and effort, using an inexpensive combination of film and developers. A series of photomicrographs are presented that compare prints made by this method with those made from Panatomic‐X.
