Silver halides.

Light-sensitive salts used in making most photosensitive materials.

Silver halide crystals are suspended in an emulsion (usually gelatin), and exposed to light to record images. This yields an invisible latent image which must then be developed. Silver chloride (AgCl), silver bromide (AgBr) and silver iodide (AgI) are the most commonly used photographic silver halides.

cf. emulsion, gelatin, halogen, latent image, silver nitrate.
