Group f/64
The group of like-minded photographers located in San Francisco who came together in 1932 to form a collective with the goal of producing photographs of landscapes and other natural forms that are distinct and clearly focused. Members such as Ansel Adams, Edward Weston, and Imogen Cunningham were a part of this club. The predilection of the members of the group to use an extremely tiny aperture in order to achieve greater depth of field is alluded to by the name of the group.
