-Black silver - finely divided metallic silver formed from silver halides by exposure and development.
-Bleach - chemical bath capable of rehalogenizing black metallic silver.
Irregularly shaped, microscopically small clumps of black silver making up the processed photographic silver halide image. Detectable on enlargement, particularly if the film emulsion was fast (ISO 1000 or over) and overdeveloped.
-Color developer - developer designed to reduce exposed silver halides of black silver and at the same time create oxidation byproducts that will react with color couplers to form specific dyes.
Photographic developer is a chemical, often a mixture of metol and hydroquinone, which converts the latent silver halide image in the exposed photograph material into reduced, opaque, black silver metal.
Bleaching: Chemical used in processing to convert black silver image into colorless compound such as silver halide.
Bounced flash: Flash illumination reflected from a ceiling or wall being diffused.
167 When such plates were exposed and developed, the colored silver in the unexposed part of the image sometimes had greater covering power than the normally- developed black silver.
