Pictorialism began 40 years before Ansel Adams started formulating his ideas that culminated in the Modernist/f64 school of thought about sharpness. In various ways and forms, Pictorialism lasted into the 1940s, but it peaked in the first decade of the 20th century and was on its way out by the 1920s. Edward Weston began his career as a semi-pictorialist, printing in platinum. And there are platinum prints by St. Ansel out there as well, but they're rare birds. Not that printing in platinum per se makes an image pictorialist. Adams, Weston, the f64 school and the Modernists were all reactions against Pictorialism because they felt photography should revel in its own inherent qualities instead of rejecting them to try and be more like another medium.
