There is an excellent Robert Adams exhibit at LACMA right now. My wife and I went to see it today and spent about an hour browsing the many photos they had on display. So many great prints and a really diverse collection of Mr. Adams' works. I just started printing in my darkroom so it was pretty inspirational. Good stuff and only $15 to get in.
