To celebrate 20 years of collecting photographs at the J. Paul Getty Museum in Los Angeles, this exhibition presents works by 38 photographers, 20 of whom are featured on the website: Manuel Alvarez Bravo, Eugène Atget, Hippolyte Bayard, Walker Evans, Roger Fenton, Joseph-Philibert Girault de Prangey, David Octavius Hill & Robert Adamson, Lewis Hine, André Kertész, Gustave Le Gray, Dorothea Lange, Lázló Moholy-Nagy, Eadweard J. Muybridge, Timothy H. O'Sullivan, Man Ray, August Sander, Alfred Stieglitz, Weegee, Carleton Watkins, Edward Weston. Each photographer's entry includes one signature picture; links to digital images in the Getty's online collection; biographical and technical information; and sometimes audio and/or video. For example, in addition to viewing Man Ray's photograph, Le Violon d'Ingres, 1924, and reading about how it was made, visitors can listen to Man Ray interviewed on his philosophy of photography, Getty curators discussing the pun in the picture, and also browse over 100 additional pictures by Man Ray at the Getty.
