Photographic film is chemically treated with developer and fixer after exposure to produce a negative which is known as photographic processing. This process transforms the concealed image into a permanent image that is insensitive to light. First the film is soaked to swell the gelatin layer. Next the developer is used to turn the concealed image to metallic silver. The film is then rinsed with clean, 20 degree water which halts the action of the developer. Then the fixer is used to make the picture permanent and insensitive to light by ridding the film of any silver halide salts that may remain. After this the film is washed with clean water again to remove the remaining fixer. Once the film is carefully rinsed it can be hung to dry. Finally, once the film has dried and been cut into smaller sections, you can scan the pictures onto the computer, where you can then make prints or upload to the internet.
