Image Permanence Institute

To photographers archival usually means negatives and prints that will last at least a century. Unfortunately, nobody knows for certain what will enable a print to last that long. Every time definitive research is announced by Kodak, the Image Permanence Institute, Ilford, or anyone else involved in archival research someone finds a spot on a print or negative that is supposedly archival by the new standard.
