Abstract
In conventional photographic processes, material being processed follows a predetermined sequence of steps, for example, developer, bleach, first wash, fixer, second wash, and stabilizer. This requires the provision of at least two wash tanks as the film is traditionally processed by following a fixed path through the processor. This makes the processor bulky as the wash tanks need to be repeated. Described herein is a process in which more than one wash step can be accommodated using a single wash tank.
Claims3
A method of processing a photosensitive material which comprises at least three different processing steps, said processing steps being carried out in an appropriate tank arranged in a predetermined sequence, each of said tanks having a different processing solution through which the photosensitive material is passed, comprising the steps of:
- passing the photosensitive material through said processor such that the photosensitive material is redirected to a previously visited processing tank containing processing solution which is different from the processing solution in the tank it just left.
