Today’s theme for the 2009 Challenge is Black & White, Shadows. The goal today is for you to really think about the broad contrast created by shadows cast. This has great potential, but might be vague for some. So, if you’re having a hard time deciding on what to shoot, wait until the afternoon, and shoot the long shadows of people walking, buildings, or cars on the highway. There, now you’re ready!

Once you’re ready to submit your work to Flickr, you’ve got to do two important things. First, make sure you tag your photos correctly; “2009challenge″. Also, if you haven’t already, join the PhotoChallenge group on Flickr. Then, submit each day’s photo to the group’s pool.
