Challenge #3 - Fernando

Hi all!
I'm really sorry about just posting one shot for the 3th challenge, but I was really busy with a local photography award (I was awarded with the second prize !)).
The title of my proposal is 'The colour Wheel'. I was trying to catch the rainbow, but here, in Cádiz, is almost impossible from april to november (well, indeed yesterday night was the lattest rain for over a month). Thus, I painted eight concentric circles in a paper with the rainbow colours. I fixed the circle to a pinwheel and I turned it on in front of the camera. I selected a slow shutter speed and a smooth light. The result is there! I hope yu'll enjoy it!
