A new technique for photo identification

Scientists at the Getty Conservation Institute in Los Angeles have developed a new method for authenticating historic photographs that will have broad implications for museum collections, art historians, collectors, and conservators. Each chemical printing process leaves behind a series of markers that collectively are as distinctive as a fingerprint. The GCI researchers have now identified the signatures associated with different photographic processes to provide a scientifically-based method for provenancing and authenticating a majority of 20th-century photographs....Getty Conservation Institute, Jan. 8
