Detailed explanation-1: -Developer solution is used in the darkroom for developing (i.e. converting latent image to visible image) x-ray films used in conventional (screen film) radiography.
Detailed explanation-2: -A chemical solution known as the developer is used in the development process. The purpose of the developer is to chemically reduce the exposed, energized silver halide crystals into black metallic silver. The developer solution softens the film emulsion during this process.
Detailed explanation-3: -Developing agents are composed of chemical compounds such as hydroquinone or phenidone that can convert exposed grains of silver halide to black metallic silver. The developing agent has little or no effect on the unexposed silver halide crystals.
Detailed explanation-4: -A clearing agent, also known as fixing agent, is the chemical that actually removed undeveloped silver halide crystals from the film. Sodium thiosulfate and ammonium thiosulfate are commonly used. These agents are also referred to as hypo.
