Like winger said it would also be helpful to study some bad work. Iīve been around in some dslr forum recently and itīs always a strange experience to browse through the nude gallery there. Never seen so many nude photos that oscillate between tasteless, unintentionally hilarious and outright degrading. I cannot understand why both the photographer and the model can be proud of such stuff. In my view it is not so much a matter of camera technique with these pictures (which seems flawless, by the way) but of personal lack of tastefulness from both sides. It definitely helped me a lot to think about what is good and what is not in nude photography.
