Abstract underside of spiral staircase.

Apologies if I have blipped a similar shot before, but in the interests of economy, I am trying to use material I have shot today. I shoot, or try to shoot everyday. Sometimes if I particularly like a shot, I will return and try to improve. With our uncertain weather, it is not always able to re-create lighting conditions. I have lightened this a little, and very slightly cropped it. I will return and try to get the shot I really want.
