I'll have to come back here as I wouldn't know where to start!  I have way too many favorites here.

But I can start with the non-DA photographers:

1- Andreas Gursky.  I think it's interesting that I found out that he's famous for a style I love, only after I've shot most of my photos.  His work is "Grand" and I love that

2- Yann Arthus Bertnard.  He's famous for his "The earth from above" book and series, but I recently got a book about all of his work, including a DVD of how he does what he does.  Amazing

3- Hofer.  Another brilliant photographer.  I think she's German but not sure. 

More to come
