I use photoshop and tag rather often, I'm sure by this point you're at a different level, but I would say not to use the B&C tool too much- it messes up the saturation, you should use the levels adjustment.
I originally made two, but the second one I made is at school. And this is the second one that I just made few seconds ago. It was a request for someone, but I guess anyone can use it too. Miku is the name i go by on the forum I go to. xD [link]
