Is Processing Solution The Same As Developer?
No, processing solution and developer are not the same. Developer is a chemical solution that initiates the chemical reaction that reduces the exposed silver halide crystals on a photographic film or paper to metallic silver, resulting in the formation of a visible image. On the other hand, processing solution refers to a broad term that includes various chemicals used in the photographic development process, including developer, stop bath, and fixer. The processing solution works in combination with developer to create a visible image on the film or paper.
