"'The best lack all conviction while the worst are full of passionate intensity' -- now you figure out where I am. -Lou Reed quoting Yeats
Speaking of passion, I found a guide of nude composition faux pas(s) in my copy of Mortensen's "The Model" that one can find either funny because you've avoided these, or infuriating if your aesthetic is featured, because, like political perceptions, it all depends on where you're coming from.
So go and shoot some nudes and don't break the rules! Haha!
See, it all comes back to photography.
