My take on this subject: a person who produce a work of art using PP is no less an artist than someone who does not do any PP at all (if this is at all possible). A great photo is a great photo. Period.
1. If you shoot in JPEG format, the camera has already post-processed the photo for you.
2. If you shoot in RAW format, how can you avoid PP?
Furthermore, between my DSLR and my computer, I know which one I prefer to have my photos post-processed with.
