Like the others have said, digital photography almost always involves some post processing some sort of processing as stated so well above, it involve invoking an emotional response. That said, I limit my post processing to enhancing the image and not manipulating it into something that you could see if you were there. I think of Lightroom rather than Photoshop. One of my most significant manipulations is when I used PS to remove a telephone wire that ran outside the door near the top. Other than that I simply use LR to bring out the best of the photo. Like I said, I feel a person should be able to go to the site and see what I saw.
Nikonians is the Smithsonian of Nikon knowledge. If there is a question they can't answer, I want to see the question.
