Hmmmm...sounds like a Poser discussion ("Is it fair to do postwork?) MHO: Of all the photography books and classes I've ever read or attended, I've never heard this debated. (that alone should say something). Personally, I would do whatever it took to get whatever photo I wanted. I will also say I feel much better IF I find a leaf just about the way I want it instead of arranging it. But that will not stop me from arranging what I want to "say".
