(Upcoming 2011 workshops in Los Angeles, Tucson, Santa Fe, San Francisco, Illinois, Boston, and New York City)

Location: This workshop will be hosted by The Andy Warhol Museum (Pittsburgh, PA)

June 6-9, 2011


Registration Includes:

4-day workshop
280-page color notebook
60x LED handheld microscope
OPTIONAL: Basic Photographic Sample Set

This 4-day workshop is an introduction to the history, identification, and preservation of photographic materials from daguerreotypes to fine art digital prints. 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.

The registration fee for this 4-day workshop is $645 and includes a handheld microscope, and a workshop notebook with lecture handouts, Quick ID Sheets for each process, and a selection of readings on photograph preservation. The Basic Photographic Sample Set, consisting of 18 identified photographic and photomechanical processes, is available with registration for $75.

Due to the hands-on nature of this workshop, the number of participants will be limited to 12.



The Academy of Certified Archivists (ACA), a certifying organization of professional archivists, will award 15 Archival Recertification Credits (ARCs) to eligible Certified Archivists (CAs) attending this workshop.
