I was photographing boulders at a shopping center when a man stopped his car, rolled down his window, and asked “Looking for fossils?” “Just the rocks,” I replied. “Boulders are nature’s abstract art.” He grinned and gave me a thumb’s-up sign and drove on.
Truth told, close-ups photos of rocks are the real abstract artworks—keeping in mind that abstracting something can mean separating it from its previous circumstances.
