Cathy - I "liked" the page! That was a great resource. Thanks
Dave - I ordered a few books from my library on Durer, Turner, and Sargent that were specific to their watercolors. Cezanne has always been a favorite of mine when I was studying oils, but I couldn't find a book on his watercolors.
It's funny, I've taken plenty of art history classes, but I really only remember water media being covered as part of the prepatory process. Perhaps the classes were just too long ago... But I also got a book called Watercolors from Durer to Balthus
which seems like an overview of sorts. I love the library.
