RadiologyOverfixing occurs when the radiographic film remains in the fixing solution for an extended period, leading to excessive clearing of the image. Fixing agents, such as sodium thiosulfate, dissolve unexposed silver halide crystals. Prolonged exposure results in a lighter image as even some of the developed silver may be affected. Other options, such as overdeveloping, directly putting in fixer, or sunlight exposure, typically lead to other issues like dark films or fogging.
