ABSTRACT:
Low silver black-and-white photographic elements, such as radiographic films, can be processed quickly using a two-stage process in which black-and-white development is carried out in the first stage for up to 30 seconds, and such development continues along with fixing in the second stage for up to 60 seconds when a fixing composition is added. Both stages are carried out in the same processing container.
