Group f/64 was a collective of photographers formed in 1932 in San Francisco, California. The group aimed to promote a style of photography that emphasized sharp focus and detailed imagery, contrasting with the soft-focus techniques popular at the time. Its name refers to the aperture setting of f/64, which allows for a greater depth of field. Key members included Ansel Adams, Edward Weston, and Imogen Cunningham. They believed in capturing the natural world with clarity and precision, often using large-format cameras. Their work significantly influenced the development of modern photography and the appreciation of fine art photography.
