Flim processing or Photographic processing is the industrial process by which conventional photographic film is treated after photographic exposure in order to produce the desired negative or positive image. Photographic processing does three things: it transforms the latent image into a visible image that can be seen, it makes the visible image permanent, and it renders the film insensitive to light.The general process is similar whatever the make of film or paper. Before processing, the film must be removed from the camera and from its cassette, spool or holder in a light-proof room or container. In amateur processing, the film is removed from the camera and wound onto a reel in complete darkness (usually inside a darkroom (with the safelight turned off) or a lightproof bag with arm holes). The reel holds the film in a spiral shape, with space Flim processing or Photographic processing is the industrial process by which conventional photographic film is treated after photographic exposure in order to produce the desired negative or positive image.

The amateur or commercial level processing , the film is treated in chemical baths. Each of these baths is closely monitored and maintained at a specific temperature and treatment time. Developer baths are most sensitive to deviations from the standard processing conditions. The fixer makes the image permanent and light-resistant by dissolving any remaining silver halides.
