Post processing was done in Photoshop CS5, with mild cropping and slight darkening (burning in) around him on the background to help tone it down and draw more attention to him. I also applied several filters in Topaz Adjust which included, Mild Contrast Pop, Mild Color Pop and Photo Pop to help bring out what I envisioned was I was shooting the portrait.
