The chemical process in developing film converts the latent image into a visible image. The four processes are developer, fixer, wash and dryer. Developing is usually done in closed canisters. The developer solution converts the silver ions into black metallic silver. This causes the grains in the picture to become visibly black. After this step, the film should be rinsed with water. This halts the action of the developer. Then a fixer is used to make the image permanent and light resistant. This is done by dissolving the silver halide salts. Then the fixer has to be washed over with water to prevent corrosion, fading, staining, or discoloration. The film then has to be dried, and cut into protective sleeves to prevent scratching of the negatives which can ruin the image. Finally, the negative can be scanned and printed for the photographer’s own use.
