Metropolitan Museum of Art, NYC
April 2–September 2, 2013
More than two hundred of the finest and most poignant photographs of the American Civil War have been brought together for this landmark exhibition. Through examples drawn from the Metropolitan's celebrated holdings of this material, complemented by important loans from public and private collections, the exhibition will examine the evolving role of the camera during the nation's bloodiest war. The "War between the States" was the great test of the young Republic's commitment to its founding precepts; it was also a watershed in photographic history. The camera recorded from beginning to end the heartbreaking narrative of the epic four-year war (1861–1865) in which 750,000 lives were lost. This traveling exhibition will explore, through photography, the full pathos of the brutal conflict that, after 150 years, still looms large in the American public's imagination.

Note: I went to this exhibit and it is well worth the time. The photos are amazing both technically and for the historic value of the subject matter. Sections are devoted to the battles, the soldiers and their life on the fields, slavery, Civil War medicine and other topics. The exhibit is well designed and documented. They even made the rooms into tents by draping the walls with canvas. It is a fascinating exhibit of photography from its very early years. I recommend it highly.

Note: I also took in this exhibit which is small and quite interesting, covering a variety of manipulations and uses of digital imaging. Not worth a special trip but if you go to the Civil War exhibit check this out as well.
