Although Mr. Scumbeast was very, very good at curating his collection, this Naked Swim number seems a bit too clear to be an amateur snapshot. Also, there's a watermark almost cropped out at
lower right that may or may not have been the photographer's. (Some blogs and websites put
those on when posting, a habit I find annoying, but sometimes understandable.) Of course,
there have been some amazingly talented amateur photographers, so who knows?
