Hi Craig
I'm not sure if everyone is trying to PP them far too much, but as mentioned previously, they are looking quite obviusly photoshopped.
Had a 30 second play and perhaps just doing a basic levels, curves and slight saturation bump will keep the photo looking "realistic" whilst improving the look of the scene.
Perhaps give it a go and see what you think. Unless this was taken in the outback of NT, they are some fairly outrageous red tones that have been introduced into the rocks. I'd refrain from using the HUE tool too much, on this (but that's my personal opinion)
If you do re-PP, I'd be interested to see the outcome...
