Darkroom Still Life, 1918, by American photographer Doris Ulmann (1882 - 1934). This grouping of mortar, pestle, bottles, vial, and developing tray conjures up the spirit of alchemy involved in early 20th century photography. Ullmann favored soft-focus platinum prints and most often used a 6? x 8? inch, tripod-mounted view camera. She is best known for her portraits of the people of Appalachia, particularly craftsmen and musicians, made between 1928 and 1934.
