Here is a link from Poynter, from a somewhat similar incident. This photog did not clone, or combine images. He burned and dodged, something all of us do, but according to the NPPA he took it too far. He wasnt fired, but the awards he recieved in the NCPPA contest were rescinded. It just goes to show journalists ethics are being tested constantly in the digital world.

What do you think is the burning too much?
At first I didnt think so, I couldn't see the harm in darkening the trees in the fire photo, or the darkened background in the firefighter's funeral photo.
You can see side by side comparisons of the images in a link a little further down the page.
I got a chance to follow this guy for a day on the job at the Charlotte Observer while I was in school, he is a great guy and great photog.
