- Photography is based on photochemical process. When a picture is taken, the silver salts in the photographic film absorb light and chemically change into metallic silver, which produces a dark image on the negative when the film is developed. The chemical involved in photography is silver bromide (AgBr), thiosulfate and real ion.

- BASIC PHOTOGRAPHIC PROCESSING CHEMISTRY Acids, Bases and Salts are all used in photographic processing solutions. The oxides are used to make acids, bases and salts but are never used directly in photographic processing. Acids are used in stop bath and fixing solutions. Therefore, they have pH values less than 7. Bases are used in the developer.

- Schulze experimented with silver nitrate and its reaction to light and the stabilizing effects of ammonia on this reaction. Physicist Thomas Wedgwood and chemist Humphry Davy attempted the first negative and positive printing method using the same silver nitrate Schulze had been testing, but was unable to preserve the image. Scientists and

- These crystals are the heart of photographic film. They undergo a photochemical reaction when they are exposed to various forms of electromagnetic radiation -- light. In addition to visible light, the silver-halide grains can be sensitized to infrared radiation.

- the rate of swelling follows approximately a second-order equation. 63 in photographic products, the swelling of the gelatin layer is controlled by coating conditions, drying conditions, chemical cross-linking, and the composition of the processing solutions. 40–44 conditioning at 90% rh and 20 °c for 24 h greatly reduces swelling of hot dried …

- When light or radiation of appropriate wavelength strikes one of the silver halide crystals, a series of reactions begins that produces a small amount of free silver in the grain. Initially, a free bromine atom is produced when the bromide ion absorbs the photon of light: Â Ag+Br-(crystal) + hv (radiation) --> Ag++ Br+ e-
