摘要： An improved developer application method and apparatus for use in electronic film development, wherein the developer is applied to a photographic film using controlled, aerial deposition of one or more stream(s) of droplets of one or more developer agents or developer components such that the droplets adhere to a targeted region of the film, rather than run off, and chemically react to allow scanning of a latent image in the film as it moves through an electronic film development scan mechanism.

摘要： 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.

摘要： It is important to control the temperature during the development stage of a photographic process in order to maximise the efficiency thereof. This is a particular problem when photographic materials are processed in high throughput processors which operate with reduced volume chemistry as these material have a tendency to cool the developer solution if not at the correct temperature. Described herein is a method for improving the temperature stability of the material (26) to be processed by heating it before processing. The material is passed through a conditioning chamber (10, 12) where it is heated to the desired processing temperature prior to entering the development stage of a processor.
