I shot this on sport/action mode with a 350d using the kit lens. I'm a total photography noob, so be nice.. The vipers on the backstretch are doing 140-160mph, but the shot stopped the wheels, didnt blur the background, etc.. so each shot looks still, not motion. How do I get the effect of blurred background/wheels? I know I'm going to look back at this post and laugh in a few weeks of practice, but thats the best way I know to describe it. All of those were action shots, not with the car still like they look.
