For most viewers today, color photography is taken for granted in art as in everyday life. This was not always the case, as documented in the Milwaukee Art Museum’s exhibition “Color Rush” (through May 19). The curators interpret the history of color photography using familiar magazine and newspaper images alongside original photographs. Hollywood movie posters and film clips, and even a slide show depicting Depression-era Farm Security Administration photos not initially released to the public, contribute to the story. A virtual Who’s Who of American artist photographers fills the exhibition galleries with thought-provoking images. Included are Ansel Adams, Eliot Porter, Harry Callahan, Irving Penn, Walker Evans, William Eggleston and Helen Levitt, as well as contemporaries Stephen Shore, Jan Groover, Joel Meyerowitz, John Baldessari and Bruce Nauman.
