Analog black and white photography involves a chemical process known as silver halide photography. In this process, light-sensitive silver halide crystals are embedded in a gelatin emulsion on the surface of photographic film. When light enters the camera and hits the film, it causes a chemical reaction in the silver halide crystals, creating an invisible latent image. During development, the film is immersed in a series of chemical baths that reduce the exposed silver halide crystals to metallic silver, forming the visible black and white image. **
