Funny thing is, when you are photographing shadows, you typically need some sun. I am horrible at photographing with artificial light, I really like natural light - and as luck would have it, it was gross and overcast today. I usually love taking pictures on overcast days (clouds are like a giant soft-box), but having a touch of sun would have made this assignment much easier.
So I took my camera with me to Nick's soccer practice tonight. It was freezing cold, but thankfully it was dry. And then I had a thought. What if I take a photo of something in the light of the moon? Not quite a shadow, but it turned out pretty cool. Glad I had my tripod with me!
