In our July Photo Challenge, we dared you readers to make photos where the shadows became the subject. The results were fascinating, as always. Here are some of our favorite shots from last month's submissions. Once you've gone through them, head over to our Contests page to see how can use your own work to win prizes. Look for the official winner of the Shadows Photo Challenge in an upcoming issue of Popular Photography.
