Mark Osterman and France Scully Osterman established Scully & Osterman in 1991. Through extensive primary research and practical application, the Ostermans have evolved as historians and modern masters of a wide variety of historic (alternative) photography, most notably, the wet-plate collodion process.

The current artistic revival of collodion photography is a direct result of their influence. They were the leaders in exhibiting and publishing their work as artists in the early 1990s, openly sharing their knowledge through lectures, publications, workshops and tutorials. Photograph conservators, collectors, museum curators and the most advanced collodion photographers turn to the Ostermans when they have collodion-related questions.

Located in Rochester, NY, Mark Osterman is Photographic Process Historian at George Eastman House International Museum of Photography & Film. Mark's unique series of workshops chronicling the evolution of photography are now open to the public. These workshops tap the extensive resources of the Eastman House collection, including period publications, inspection of vintage masterworks and equipment from the archives.

France Scully Osterman is an artist and educator. She and works and teaches in their skylight studio, and gives lectures and workshops at universities and museums in the U.S. and internationally.

The Ostermans are both represented by Howard Greenberg Gallery, NYC and Tilt Gallery, Phoenix, AZ.
