My family and I were on a cruise and one of our stops was in Valencia. While on a city tour we stopped at the City of Arts and Sciences complex. This amazing series of buildings was beautiful and I noticed these gigantic blue tiled structures surrounding the perimeter of the greenhouses. I took this picture as an experiment of depth of field and I think it turned out quite nicely. f/9.2, exposure time: 1/320 sec., focal length: 17mm, ISO: 125, aperture: 3.6
