Final answer:
Analog photography uses film to capture images and relies on chemical processes to develop them. Continuous tone photographic images are developed by exposing the film to light, processing it with developer and fixing solutions, and then printing it onto photographic paper.
Step-by-step explanation:
Analog photography is a traditional form of photography that uses film to capture images. It involves the use of a camera with a lens and a light-sensitive film that records the image when exposed to light. Unlike digital photography, where images are captured electronically, analog photography relies on chemical processes to develop and produce the final image.
To develop continuous tone photographic images in analog photography, the film is first exposed to light through the camera lens. This creates an invisible image on the film's emulsion, which contains silver halide crystals. The film is then processed in a series of chemical baths to bring out the visible image. The first step is to develop the film by treating it with a developer solution, which converts the exposed silver halide crystals into black metallic silver. Next, the film is fixed using a fixing solution, which removes any remaining silver halide crystals that were not exposed to light. The final step is to wash the film to remove any residual chemicals. The developed film can then be printed onto photographic paper to create a continuous tone photographic image.
