#2304: looks strange, as the forms and shapes come over and over again... what is it?
Not really. When you use extension tubes, or simply a long macro lens, if you pay attention to the periphery, you will notice many out of focus areas. In this case, they are like patterns, so I use them creatively. One of the easiest to do is repeating motifs, like other out of focus petals or flowers, strategically arranged. These were only done one hour ago. But I got so excited after I got my extension tubes, I had to try it and post it! Give it a try.
