Circular - agh! as soon as I started looking everything was circular - eyes, flowers, car wheels and lights, the DVDs on the desk... walking past the bathroom I spotted some sea urchin shells (well, not technically shells...) and remembered how much I love all the circular patterns on these - so they are my test subject for the day. Photographed on macro setting (handheld), sitting on a black T shirt with natural light from the window, a little sharpening and contrast from PS. Probably wouldn't have needed the sharpening if I had dragged out the tripod eh?
I found these on a beach in the far north of Australia after a storm, there were literally thousands of them along the beach.
