I ran into photographer friends Shannon and Brian Voges at Badlands Motor Speedway in Brandon a couple weeks back. We had a discussion about panning, especially with things moving as fast as sprint cars on a dirt track.
One of the secrets to photography is shoot a lot and learn from the bad ones. The key to successful panning photography is moving at exactly the same speed as your subject matter...and shooting a lot. For every good shot, I have a lot to throw away like these.
But when it works, the successful images are really fun.
