Archival Print Processing.

How long does a Photograph last ? Some of the first ever made have held up perfectly, their images as durable as if they had been carved in stone. For Black and white Photos, archival processing is not very different from customary method of developing, fixing and washing. It basically an extension of the ordinary procedures, involving a few extra steps.
During development, those grains of silver salts that have been exposed to light are reduced to black metallic silver, which forms the image; but unexposed grains are reduced and remain in silver form of a silver compound.
When these silver-fixer complexes decompose they produce a brown-yellow compound may discolor the entire print. Archival processing includes procedures that eliminate the traces of residual chemical that washing alone cannot entirely remove.
