High Key Post Processing

Recently in my advanced portraiture class we shot out high key\low key assignment. I chose to shoot low key myself. Other students choose to do high key which is more difficult because you have to use more that one light to get the background pure white. These high key situations reminded me of a video Gwinnett Technical College commercial photography graduate Zack Arias put together of post processing of a high key shooting situation. He gives a lot of great info here.
