The Daily Universe: Black voices amplified in photography exhibit. “The project features portrait photographs of 76 Black women, men and youth made using tintype, a photographic process that dates to the Civil War era. In tintype photography, a thin metal plate is coded with a chemical called collodion. The plate is then sensitized to light with silver nitrate and inserted into a non-digital, accordion-like camera called a field camera. The field camera is then exposed to light, embedding the image onto the plate.” The project is also available online.
