In my humble opinion, PP is just part of life for digital photography. No need to be ashamed that you're doing it. PP is not just to correct mistakes, in fact I don't think that should be its main purpose. The purpose is to show the photo the way you want it. I never show anyone unPPed images these days, as I think there just isn't enough care put to it yet if you haven't PPed it in some form. In film I can select film to get the look I want, then why can't I do PP in digital to do the same? And if you argue that you can select JPEG setting to get the look you want, I will ask is do you put yellow filters to put contrast in your B&W images instead of PP?
What he said...
...except for the bit about yellow filters.
While it is possible to dial in a certain amount of filter affect in PP, I have found that I get better results shooting RAW with colored filters with white balance set to daylight. I then do the BW conversion in Lightroom.
