When you take a shot like this they can be a little bit, well, flat....it can be hard to distinguish the subject (the tree stump) from the background.
What I did here was pretty simple. Made a copy of the original, changed the brightness level, added a mask and then painted back the background as I wanted it to be. In the old days of darkroom alchemy we called it 'dodging and burning'. Now we call it a 'doddle'.
Have a go.
