I've been reading through a Breakout called "Connected: Shooting from the Heart" by Anne Wick. It's a great session and I'm just about half-way through. I stopped to work an exercise focusing on capturing little subtle facial expressions. These are a few expressions that I got from two of my boys. Justin better look out, because he is next. I used window light and monitor light. I spot metered off the brightest part of their faces and used a gradient map during processing.
