Start to Finish
When you expose film to light, by opening the shutter, the light reacts with the light-sensitive silver-halide particles in the film emulsion. At this point, the reaction is invisible. The film must be developed in order for the reaction to be visible. The film is developed using a chemical developer, which turns the exposed silver-halide particles into a black metal . The film stays in the developer for the correct time to turn the right amount of halides into silver. The dark areas in the original image will have the least amount of silver on the film, and appear transparent. The lighter areas, conversely, will have the most silver. This effect is why the developed film is called a negative. In order to stop the development process, a stop bath is used. It neutralizes the effects of the developer. At this point the film is developed, however the image is not permanent, there are still unexposed silver-halides in the emulsion. If these particles are exposed to light, they will turn into silver quickly. The film has to be made permanent, this is done with a chemical fixer. The fixer attaches itself to the unexposed silver-halides, preventing them from reacting to the light. The final stop is to remove all traces of the chemicals in a wash step. If fixer is left on the film, it will eventually stain the image. There are additives, like Kodak Hypo Clearing Agent, which can speed up the wash process. After washing, the film must dry.
