From the invention of photography in 1839, architecture was second only to portraiture as the most favored subject for the camera. The fact that buildings were immobile was advantageous for the long exposures needed in the early days, but architectural images were popular for other reasons: they documented dynastic, civic, and religious achievements; educated architects about construction and decorative details; and whetted curiosity about distant lands. Later photographers found innovative ways to depict structures of every era and type. Arranged chronologically, 'Architecture in Photographs' spans the history of the medium and includes works in a variety of photographic processes by such distinguished nineteenth-century practitioners as Henri le Secq, Gustave Le Gray, and Roger Fenton; twentieth-century photographers Eugène Atget, Alfred Stieglitz, and Walker Evans; contemporary artists Ed Ruscha, Lewis Baltz, and Steven Shore; and younger image makers Catherine Opie and Michael Wesely.
