Sprint dog racing is in full swing in Fairbanks this time of year, even as the long distance mushers work their way towards Nome on the Iditarod. The Limited North American took place last weekend, with four, six and eight dog classes. These teams really move fast and it is no small challenge to attempt tight compositions while they speed by. Auto focus tracking tracking and a high burst rate are essential, and even then, there are many frames to throw away. I shot a few thousand pictures, mostly with the Canon 1D due to its 10fps speed. Generally, I selected 400 ISO and shot between 500-1000 shutter speeds, giving me an f-stop from f11-f13 or so. It was a sunny event, and a chilly one too. I'll probably throw away 90% of the photos, but captured a few good ones.
