And, in case you were wondering, silvering is a deterioration to the original photograhic chemicals that were placed on the paper (The chemicals were held to the paper by a coating of gelatin, thus the name 'gelatin-silver photograph.' Without the gelatin coating, the chemicals would simply slide off like sand). In later years, they changed the chemcial formula and the silvering no longer would appear. |
