As a macro photographer, I love capturing small details of small things, and it always makes for interesting images. Many times, the photos themselves offer an air of mystery as to what they are, and it's always fun to present them to other people to guess what they are.
Mystery photos aren't always macro photos. This one was shot with a wide angle lens, and is not too hard to figure out! I am actually considering making a "What Is It?" Series for subscribers. I probably have a few hundred suitable images (and can always create more) that I can post monthly, or a few times per month. Let me know your thoughts!
