Pictorialism, Photo-Secession, and Straight Photography were three major photographic movements between 1870-1930. Pictorialism aimed to express feelings and engage the senses through manipulated images focused on beauty rather than facts. The Photo-Secession movement was founded by Alfred Stieglitz in 1902 and sought to elevate photography to an art form while respecting its mechanical origins. Straight Photography emphasized photography's technical capabilities to sharply depict scenes in focus and detail without manipulation. Major figures included Edward Weston, Ansel Adams, and Imogen Cunningham who were part of the f/64 group that further developed Straight Photography.
