to me nature (and indeed photography) is getting everything right 'in camera' as much as possible. The only post processing I do is curves / levels adjustments the occasional blend (from braketed shots when shooting into the sun) and thats about it Having the scene as it was, how you saw it etc
I agree. I try to do as much as I can 'in camera' not only because it is more skillful, but because you tend to get a better image... yeah Photoshop helps, but there's nothing as satisfying as getting a beautiful image without any artificial assistance.
Though I have to admit, if I can really enhance my photo (even something simple like whitening teeth for portraits) I will.
