silver bromide
Quick Summary
Silver bromide (AgBr) is a chemical compound that is extremely sensitive to light. This property makes it a key component in photographic materials. It is a halide mineral that forms a solid-solution series with silver chloride, meaning bromine can replace chlorine within its crystal structure.12
Silver bromide is used in photographic papers, often suspended in gelatin to create an emulsion layer. This compound is derived from silver nitrate, which is a significant inorganic silver salt.34

…photosensitive chemicals silver chloride and silver bromide. These silver salts are prepared by adding sodium chloride or sodium bromide to a very pure solution of silver nitrate. The highly insoluble silver chloride or silver bromide then precipitates from solution. All processing takes place in the absence of any light.

technology of photographyThe latent image… crystals or grains (the emulsion)—typically silver bromide with some silver iodide. Exposure to light in a camera produces an invisible change yielding a latent image, distinguishable from unexposed silver halide only by its ability to be reduced to metallic silver by certain developing agents.
