Thanks! I believe for all the shots I was using Av and spot metering. So thats probally the reason for overexposure. Looking back I wish I would have just used manual. It was definitley a lot of fun and very challenging trying to keep up with him.
My philosophy (feel free to comment): If you know what you want out of the image, using Av/Tv is fine. Why worry about setting both values manually, when you're usually only concerned with one. Let the camera put the needle on "0." You have other things to worry about.
I hope that was clear.
