I took this image at Longwood Gardens in PA. The Cacti were backlit by outside light on a very cloudy/rainy day. Canon EOS 40D, 70-200mm at 145mm with 24mm extension tube, ISO 100, f/3.5. 1/250. fill flash -2 1/3 with diffuser. I question if this is actually considered a macro or just a close up but I will call it a macro until told otherwise.
