Depth of Field layer mask

This was actually a lot easier than any of the mask techniques. At least for me :)
ASU opening football game 2006. I wanted the face in the foreground to be the most in focus. I used differing shades of grey on the body up to the guy with his mouth open in the background. The rest is black once I created the Alpha Channel. Came out pretty good. I am definitely going to use this technique more often. I also tweaked the blues to make them more vibrant and adjusted the levels to make the blacks and mid tones a bit darker.
