Alfred Stieglitz by As a student studying photography in Germany with Hermann Vogel, Stieglitz experimented with various photographic processes including carbon prints, gum prints, and platinum prints as well as a wide range of papers. With the onset of World War I, metals such as platinum became expensive and difficult to source which prompted Stieglitz to experiment with palladium prints and gelatin silver prints. Some of Stieglitz’s most beautiful prints of Georgia O’Keeffe are platinum and palladium prints, which have a warmer tonal range of lush blacks, blue-blacks, browns and subtle grays, however, he made stunning gelatin silver prints throughout his career, an example being his artistic exploration of clouds in his series Equivalents taken from 1922-1930.
In the Darkroom : an illustrated guide to photographic processes before the digital age by Stieglitz's first camera was an 8 x 10 plate film camera that required the use of a tripod. He purchased the camera when he was a student in Germany and used it to photograph landscapes and laborers while he travelled around Europe. In 1892, he purchased his first hand-held camera; a Folmer and Schwing 4 x 5 plate film camera which he used to take the well-known photos Winter, Fifth Avenue and The Terminal. The hand-held camera allowed for more spontaneity than a large camera mounted on a tripod. - - Alfred Stieglitz: Pioneer of Modern Photography
