Every month, we issue a challenge to our talented readers to go out and capture a great photo with a certain topic or technique. During February, we asked that you capture sports with a slow shutter speed. The results were, as always, impressive. The official winner will be announced in an upcoming issue of the magazine, but for now, here's a gallery of some of the most interesting submissions, presented with the original captions provided by their submitters.
