I just wanted to mention this for anyone in or near central Texas that may not already know. There is an exhibit of 126 original Ansel Adams photos, printed by Adams, in the Harry Ransom Center on the University of Texas campus. It's a great exhibit. It's open every day except some holidays, and it's free. The exhibit will be on display until January '06. I saw quite a few prints I'd never seen before...all very impressive. If you live in the area, there's no excuse not to go.
Here's a link for info (no pictures):
