The oxidative degradation of the image-forming substance in silver gelatin photographic prints is reviewed. Examination of the particles of elemental silver by transmission electron microscopy (TEM) revealed that oxidized silver ions migrate away from large silver grain centers before reacting chemically to form either silver salts or colloidal silver. While this migration of small image particles appears to be irreversible, silver salts resulting from the oxidative attack on elemental silver can readily be converted back to image silver to yield acceptably restored photographs. -- AATA
