The Developer and Fixer solutions are well named. All brands of film chemistry work according to the same basic principles. When light or X-radiation strikes a piece of film, the sensitized silver compound suspended in the emulsion undergoes an invisible chemical change. This change creates what is called the latent image. Developer converts this invisible image to a visible image. However, this “developed” image is very unstable and if exposed to light or X radiation will almost instantly turn completely black. Fixer sets the image so it is stable in light and permanent, in effect “fixed”.
