Abstract

The uniformity of film development was investigated for eight different film developing methods including both hand and machine processes. Film uniformity was quantitated through microdensitometry by scanning rolls of uniformly fogged and developed film with an Olympus MMSP microspectrophotometer and a Photometrics EDP scanning microscope. The results of this study showed that significant differences of uniformity were produced using the different developing methods evaluated. With the exception of the tray and hand brushing method, all the machine processors studied produced films having significantly better uniformity than any hand methods evaluated.
