While photographers have been chronicling the visible world for 159 years, their varying approaches to similar subjects underscore the creativity and flexibility of the medium of photography. This notion manifests itself by the pairing of twenty sets of European and American photographs selected from the permanent collection. The themes of architecture, landscape, portraiture, the figure, war, protest, abstraction and the passing crowd are explored through the pairings of Carleton Watkins and Ansel Adams, Edward Weston and Harry Callahan, Peter Henry Emerson and Lois Conner, Lewis Hine and Lisette Model, Walker Evans and Berenice Abbott, Alfred Stieglitz and W. Eugene Smith, and Minor White and Dorothea Lange.
