I have a photographer friend and client that is not a content provider, but does shoot custom content sometimes and occasionally lets go of some sets.
His work is Extremely unique.... The site I run for him focuses more on his fetish style (
http://www.femmeXotique.com ) but his portfolio site where you can view his Artistic Nude stuff is (
http://www.femmefete.com )
If you want really high quality artistic nude content, hit him up in email at contact at femmeXotique dot com , and tell him Ivy sent you
