film development

Film development is the process of turning exposed photographic film into a visible image. After exposure, the film contains a latent image that needs to be revealed through chemical reactions. The film is first immersed in chemicals called developers, which convert the exposed light-sensitive silver halide crystals into dark metallic silver, forming the image. Next, a fixer removes the unexposed crystals, ensuring the image is permanent and stops further changes. Finally, the film is washed, dried, and sometimes scanned or printed. This process preserves the photograph, transforming the latent image into a stable, viewable picture.
