Idea Photographic: After Modernism

Idea Photographic: After Modernism is a contemporary view of history from the photography collections at the Museum of Fne Arts in Santa Fe, the Princeton University Art Museum, and the San Francisco Museum of Modern Art.

In the following pages, the concepts and themes found throughout the history of modern photography are examined, time and again, as they evolve, taking different turns and finding new direction.

The thematic groups, some in which late modernist works are paired with earlier works, offer a comparative context and establish historical relationships among some artists, interactions not previously recognized.

Throughout, Idea Photographic is intended to provide a rare overview of the evolution of photographic ideas from modernism into the new century.
