Here are some websites that I find very useful or inspirational: – you can purchase textures here or just take advantage of their tutorials and peruse the blog. – heard of the Orton Filter or Effect – this is the creator. Check out the impressionistic work of Michael Orton. – need some inspiration. Check out the work of Harold Davis. He does some very nice floral work. – here is some great black and white inspiration from Michael Kenna.
