ABSTRACT

This chapter presents several developer types that do not readily fit into other categoriestwo-bath, water bath, high and low contrast, and ascorbic acid developers. To achieve a dramatic effect, use a specially formulated low contrast developer. The stock solutions of most two-baths will keep for 6 months in tightly sealed bottles. Solution A can be used for up to 20 films. The inexpensive, replaceable Solution B should only be used for 10 rolls of film. King points out that definition will be highest and grain lowest when all films are developed to a fairly low contrast. King suggests that with two-bath development, presoaking for three minutes may be desirable with modern ultra-hardened films, to aid absorbtion of the first solution of a two-bath. The first thing to do when formulating a low contrast developer is to select one of the agents whose reaction products decelerate development.
