This 4-day workshop is an introduction to the history, identification, and preservation of photographic materials. Participants will acquire hands-on identification skills and learn practical photograph preservation techniques. Using handheld 60x microscopes and a large set of photographic and photomechanical samples, they will learn how a variety of processes were created, why they look the way they do, and how they deteriorate. Knowledge about photographic processes is essential to their preservation and leads to a greater appreciation of the aesthetics and history of photographic prints.
Preservation topics include enclosures, handling guidelines, environmental monitoring, the effects of temperature and relative humidity on collections, and the importance of cold storage for certain photographic materials. Processes examined in detail include but are not limited to the following: daguerreotype, albumen, collodion and gelatin printing-out processes (POP), matte collodion, gelatin silver, photogravure, offset litho, letterpress halftone, collotype, chromogenic color, inkjet, and dye sublimation. Group ID sessions, using a digital microscope and screen projection, will allow participants to practice their identification skills in a guided setting.
Who should attend:
Archivists, curators, collection managers, special collections librarians, conservators, and many others can benefit from this workshop.
By the end of this program, participants will:
- Be able to identify a range of photographic processes
- Understand, be able to describe, and know how to prevent various types of photograph deterioration
- Be able to more accurately date a photograph using the material evidence such as process and format.
This workshop will take place Tuesday through Friday, from 9:30 AM to 5:30 PM each day.
