Snapped on an iPhone 4 and modified with the Camera Plus app, this photo offers some great contrasts, such as the lovely autumnal colors of the trees topped by a brilliant blue sky.
Paul Gowder tells Mashable how this ace shot came about.
"The photo was taken while my daughter and I were swimming in the neighborhood pool. I saw the clouds forming and kept thinking this would be a great photo. So I got out of the pool and got my iPhone to call my wife. I asked her to bring down my SLR. While I was waiting I was able to get this shot with the iPhone. By the time she arrived with my SLR it was gone," says Gowder.
"The best camera is always the one you have with you!"

This surreal shot was captured in an unlikely location -- a Target car park. Barry Cullum explains how the image came about:
