Definitions

  • the processing of silver halide photographic materials is performed by a multiple step sequence. Initially, a silver halide emulsion located on a film substrate is exposed to radiation which produces a latent image in the silver halide grains of the emulsion. Thereafter, the latent image is immersed in a developing solution which contains a reducing agent or developer. Typically, developers include hydroquinone-based compositions. Once the image is reproduced on an image substrate a stopping solution is applied to the print to arrest the developing process. A fixing agent may be added and the print may be washed to remove all residual chemical compounds.
