Developers
In film developing, photographic developer (or just developer) is a chemical that makes the latent image on the film (or print) visible. It does this by reducing the silver halides that have been exposed to light to metals of elemental silver in the gelatine matrix. As a generalisation, the longer a developer is allowed to work, the greater the degree of reduction of the silver halide crystals to silver and therefore the darker the image.
