I spent the weekend taking pictures of these races. This was by far one of the most challenging photography I have ever done. The track quickly went from bright white snow to shaded snow, Getting the exposure correct, with the right DOF, and stopping the action all in one made for some experimenting. I used good glass and that helped tremendously.((EF 70-200 f/2.8L IS USM). Here are a few of them. Any critiques appreciated.
