The three tanks (Developer, Stop bath, and Fixer) are placed in a tempered water bath. An inexpensive plastic dishwashing tub seems to work very well for this purpose. Each tank contains one liter of solution. Actually, the tanks are capable of handling a slightly larger amount of solution, but one liter is sufficient to completely cover the films. Plain water can be used in the center tank, instead of acid stop bath, if an alkaline processing regime is being used. The center tank can also serve as a water pre-soak bath, if desired. A pre-soak is not an absolute necessity, since there is no danger of the films adhering to one another with this method. Also, Ilford does not recommend the use of a pre-soak. It seems that they have incorporated a wetting agent into the emulsion, or the coating of their films. They claim that pre-soaking may remove the wetting agent, possibly causing uneven development.

The full gamut of photographic printing processes may be little-known to contemporary photographers, who have been educated largely within the mainstream of the silver-gelatine tradition. My intention here is to help restore some of the ‘lost’ options by providing you with a handy reference list of the better-known alternative processes and an outline of their characteristics and working methods, without any detailed formulae or procedures. This should enable you to decide if 'there might be anything in it for you’. If so, then the texts listed in my bibliography should provide you with an entry into the practice
