Developing bath is an important step in the photographic process. It is the chemical process in which an exposed but undeveloped photographic film or plate is treated with a developing solution to make the latent image visible.

The process begins with the photographer loading the exposed film or plate into a developing tank. Then a measured amount of developer is added into the tank, and the film is agitated for a certain period of time. This process converts the silver halides on the film into metallic silver, creating the tones and contrast of a negative.

Developing bath can be used to develop both black and white and color film. With black and white film, the development time and temperature vary depending on the type of film, the light-sensitivity, the contrast requested and the quality of the developer. Color film is usually developed in a color developer, also known as a C-41 process. It usually consists of three different solutions that work together.

The developing bath is an important step in photography, as it completes the process of converting an exposed film into a usable negative or positive, depending on the film type. It is critical that the exact timing and temperature for the developing bath is followed in order for the results to be optimal. Any deviation from the specified process can result in an under- or over-developed negative or positive.
