Friend and I went to see Stieglitz and His Artists: Matisse to O'Keeffe yesterday and I highly recommend this exhibition.
Stieglitz was not only a master photographer but also a fierce supporter of American and European modernists when they were not popular or the latter even known state-side. The exhibition shows a wide range of pieces from his collection plus some photography of his.
I enjoyed the way of presentation and the background that was given - I must admit that I was not familar with the works of Marin so that was very interesting to me.
The exhibition is only on display until Jan 02, 2012 at the Metropolitan Museum of Art so you better hurry if you are interested.
