Blue Hour at Garda lake

Camera on tripod. See EXIF. I took this picture a few weeks ago close to Porto village(East side of Garda lake). Strange colours and reflections of that moment caught my attention. A few stars were on the deep blu sky. Boats and water were almost static. Just a little bit of rolling due to a fast motor-boat that "curved" water and moved the boat on the right, while taking piccies. Main mast (the fourth from right) is a little bit blurred. I filled compo with pebbles in foreground. They were under the surface of water and appeared very useful and interesting to me at that moment. HDR capture putting together 7 different files.
