Printmaking
Timothy O'Sullivan was an American photographer who documented the American West and geological surveys during the 1870s, producing some of the earliest large-format landscape photographs of the region. Working with wet collodion on glass plates, he captured vast canyon formations, mining operations, and indigenous settlements with a formal, architectural precision that transformed landscape photography into a scientific instrument. His work appeared in official U.S. Geological Surveys and established photography as essential to westward exploration and territorial mapping.
