Here is a photo I took recently at the park. I read somewhere that photographing birds in flight is good practice for action shooting, and as I want to be able to take good ski photos, it made sense to me. This was my first day out shooting birds, but this one came out the best. I realize the crop job is a bit hack, but I am more interested right now in being able to take sharp action pictures that are properly exposed. Let me know what you think. f/5.6 400, iso400 and 135mm focal length with a 40D and a 28-135mm lens.
