These two exhibitions are well worth seeing if you are in the vicinity or can travel to Glens Falls, NY. I take it that all the photographs are from the collection of Michael Mattis and Judith Hochberg. The Adams includes some interesting early prints of some of his iconic pictures, and the Photo-Secession show is very comprehensive. More information:

Up through April 20th.
