I really haven't done much landscape photography in my career, and am not very good at it.  However, I am learning.  While in Yosemite, I took a class with Gary Hart Photography.  It was incredibly informative about landscape photography in general and specifically to the park.  As well, Gary had an immense knowledge of the park's history which was very interesting to listen to as he would describe scenes.  I couldn't have asked for anyone better to show me the vastness of Yosemite.  After his session, it was a lot of 4:30 wake up calls and staying out past sunset (and at least one broken camera), but it was fun.  I didn't get anything that knocked my socks off, but I will keep at it.
