Definitions
- either the amount of silver halide of the material or the amount of developer in the developing solution or both the amount of silver halide and the amount of developer or the development time can be drastically reduced and a color-rich image can still be obtained if the treatment is carried out on the development step with an oxidizing substance, the so-called amplification step can follow, H 2 O 2 or an H 2 O 2 -releasing agent being used as the oxidizing substance (development amplification process).
- antioxidants e.g. Hydroxylammonium sulfate or chloride, amidosulfonic acid, hydrazine and Hydrazine derivatives and ascorbic acid, of which hydroxylammonium salts are already preferred as antioxidants in photographic processing baths for the usual process without an amplification step (e.g. E6 process from the Eastman Kodak Company), but without to increase sensitivity.
- E6 process from the Eastman Kodak Company
- the silver halide emulsions usually become chemical matured, for example by the action of gold compounds or compounds of divalent sulfur.
