Hello All,
Along these lines Dr. Dusan Stulik from the Getty Institute gave a wonderful presentation at APIS this year about the identification of photographic processes. He stated the single most important thing the photographer could do is make sure the process is identified on the print for future, Pl/Pd, Carbon, Silver, etc. This was to make life easier for conservators in the future. At the Getty they now have ways to identify the process with out even touching the print and can tell exactly what was used in making the print.
