Hi, there is an exhibition at the Victoria & Albert Museum, London, called "Alfred Stieglitz: Georgia O'Keefe" until 19 March which sounds very well worth seeing. To quote The Independent "This is a tiny show, but classy and memorable. When you have finished you can stroll through a selection drawn from the museum's huge photo collection, including works by Bill Brandt, Irving Penn and the French master Henri Cartier-Bresson".
