How to judge the Authenticity of Photographs
Bert Stern, Marilyn MonroeHow to judge the authenticity of photographs? This is an important question for buyers of photographs at auction houses and galleries. David Rudd Cycleback is an art historian specializing in the issues of authenticity and has published an Online Guide as well as the book Judging the Authenticity of Photographs
which is much more detailed. Cycleback explains the concepts of original prints, vintage prints, printed later, etc. and how to identify the different types of prints like albumen, chromogentic or gelatin silver prints. So the reader gets some basic information about the imaging processes and the history of photography. It's very important to use a microscope of 30X to 100X power to examine a photograph. Cycleback presents some examples e.g. how to identify photoengraving or collotype. Judging the Authenticity of Photographs is a standard work for collectors of photographs who would like to avoid to buy falsifications of vintage prints like digital prints.
