Shadows are a crucial part of any photograph, but they rarely get the spotlight as a photo's primary subject. That changes this month. Your challenge is to make a photo that makes the shadow the star. Be creative and check out this quick how-to to get you started. Send us your best effort by August 1, 2012 and you could win $100 and get your photo published in Popular Photography Magazine.

EDITOR'S NOTE: We've been getting several entries in this contest that use silhouette rather than actual shadows. Many of them are beautiful, but this contest is limited specifically to shadows created by placing an object between a light source and another surface. However, at least we now know we have a lot of great photos to look forward to if we do a silouette photo challenge!
