Squirrel watch.
I often wonder what others have done to their pictures if anything and I know some of you don't but I always used to fiddle in the darkroom to, so it's no surprise I still fiddle now, looking to get the best out of a shot.
So what did I do to this. Well the original shot was a bit flat, taken against the light and given 1.5 stops extra exposure. it also left the sky burnt out. So first thing to do was to convert to B&W. I then used the curve tool in it's individual channels of red green and blue, of which red always has the most dramatic effect to separate dog from background. This still left me a white sky. So I copied the image onto another layer and used the green curve to darken the sky. I then painted that darkened sky back in on the original picture. I quite deliberately didn't do that evenly. Final thing was to just enhance the catchlight in his eye with the clone tool, just making it a bit bigger. And there you go that's the best I can do, I think.
