Collaboration: A Potential History of Photography is a research project and a pedagogical tool that explores the event of photography. This project was conceived and produced by Ariella Azoulay, Wendy Ewald, Susan Meiselas, Leigh Raiford and Laura Wexler, who worked collaboratively to study over 100 photography projects, created between 1860 and the present. Based on the assumption that a degree zero of collaboration is at the basis of the event of photography, this project explores photography through the lens of collaboration. It proposes a potential history of photography that is different from the dominant history of single photographers and their approach and techniques through a study of the material, practical and political conditions of collaboration.
