Experiment 16. Black-and-White Film Development

When film is exposed to light, the silver compounds embedded in the film emulsion undergo a chemical reaction and produce an image that can be made visible by application of developing chemicals. A negative developer reacts with the emulsion and removes the unaffected silver halides. A stop bath halts the developer action and a fixing compound sets the silver image of the subject on the film. Figure 16.1 shows the equipment necessary to develop black-and-white prints. Figure 16.2 shows the components of a darkroom.
