Group f/64 or f.64 was a group founded by seven American 20th-century San Francisco Bay Area photographers who shared a common photographic style characterized by sharply focused and carefully framed images seen through a particularly Western (U.S.) viewpoint. In part, they formed in opposition to the pictorialist photographic style that had dominated much of the early 20th century, but moreover, they wanted to promote a new modernist aesthetic that was based on precisely exposed images of natural forms and found objects.

Dody Weston Thompson was a 20th-century American photographer and chronicler of the history and craft of photography. She learned the art in 1947 and developed her own expression of “straight” or realistic photography, the style that emerged in Northern California in the 1930s. Dody worked closely with contemporary icons Edward Weston, Brett Weston and Ansel Adams during the late 1940s and through the 1950s, with additional collaboration with Brett Weston in the 1980s.
