Yosemite Valley, Thunderstorm by Ansel Adams
If your lucky enough to come across one of his originals (or even better inherit one) hold onto it, because they are priceless these days.
Needless to say we had to settle for a print from his online studio http://www.anseladams.com/, but once framed it takes pride and place in our bedroom.
And while Ansel Adams took beautiful photographs all around California, I will always associate him with Yosemite.
