Advanced Print Identification and Characterization for Photographic Collections

Photographic print identification is challenging as several print types are difficult to distinguish from one another. This workshop will focus on identification of perennially difficult to identify processes, including matte albumen, matte collodion, early and toned silver gelatin, platinum, and photogravure. Additional viewing will include gum bichromate, bromoil, bromoil transfer, and combination processes, such as gum over platinum. Workshop participants will strengthen and develop new identification skills through workshop demonstrations and hands-on examination exercises using the Image Permanence Institute’s study collection. In coordination with the George Eastman Museum, participants will also learn how analytical techniques such as microscopy and X-ray fluorescence spectroscopy can aid in print identification. Two days of the workshop will be held at the Image Permanence Institute (IPI) utilizing IPI’s research collection and the third day will take place at the George Eastman Museum viewing and analyzing objects from the museum’s photography collection with conservation professionals.

The workshop will be limited to a maximum of 12 attendees. Registration per individual is $650 and participants are responsible for their own travel, meals, and lodging costs. Registration ends September 20, 2022. With the safety of our staff and attendees foremost in mind, COVID-related safety guidelines and precautions will be followed and participants must agree to meet the RIT Safety Plan. In the event that circumstances change, and health and safety guidelines require cancellation of the in-person sessions, the workshop will be rescheduled.


Collection professionals who possess fundamental print identification skills and are looking for an opportunity for concentrated looking and learning about difficult to identify processes, including matte albumen, matte collodion, early and toned silver gelatin, platinum, photogravure, gum bichromate, bromoil, bromoil transfer, and combination processes, such as gum over platinum.
