The sad thing is, the trend is actually going towards such form of Ps-ing. Take a look at many of the awards in the photojournalism world, and you will see that a lot of works have selective editing applied to give the pictures a lot more punch than reality.
The danish photographer technically used tools which are allowed in the general code of ethics by photojournalism (curves, saturation), but he has obviously changed the reality of the original shot that it looks more like a photo illustration.
A lot of these people are doing good work, yet I guess their pride in their work has led them to do some very dramatic things that borders over good taste and bad judgement. Remember some of the very dramatic black and white shots taken in the 1950s? A lot of them have undergone extreme dodging and burning, and it would have been debatable in today's world where the scrutiny on manipulated work is a lot stronger.
Reminds me of this incident where a Chinese photographer claims to have waited for 8 days and 8 nights to capture this image.
