DARKROOM TO DATA is a symposium hosted by the Lens Media Lab featuring the lab’s research into the material history of black and white photography and providing a forum for our principal collaborations, including contributions from colleagues at the Center for Creative Photography, The Metropolitan Museum of Art, and Solomon R. Guggenheim Museum. The theme of this work is “seeing at scale” through the creation and interpretation of datasets that surface patterns latent in photograph collections. These patterns inform our thinking of artistic intention, regional practices, and the influence of materials and methods shared by photographers across time. The intended audience is art historians, conservators, conservation scientists, collectors, curators, dealers and anyone interested in data science and data visualization applied to the study of cultural material.
