Thanks for sharing. My wife and I often take day trips or weekend trips to Atlanta just to see exhibits at the High. Anyone that doesn't know about the High that lives in the south should check it out. They almost always have major photo exhibits.
Jackson Fine art in Atlanta also has some great shows. We're were recently at the High and Jackson for Gordon Parks and Bruce Davidson shows. In the past the High has had Exward Weston, Ansel Adams, W Eugene Smith, Mann Ray and dozens of other big name shows. I've even attended lectures by some of the living artists.
If you're in Nashville check the Frist Museum. The Frist has major photo shows too. The had a show of images and vintage cameras a few years ago. Among the prints were images by Weston, Adams, Avedon, Horst, Imogen Cunningham, Steichen, Stigletz, Tina Modotti, Paul Strand and many more. They had a major show of HCB's work. There were probably over 100 of his prints. Another show was prints of every Pulitzer prize winning photo.
