I had some spare time to spend, so I climbed up to the square in front of the Rivoli castle, with the Collegiata Alta bell-tower and Turin hill in the background . Even if not late, it was almost night, and i took some shots to get some colors which are available just for few minutes at the dusk. Color balance in this kind of image is always a compromise, and the contrast between the cold sky and the warm artificial light usually results in nice postcard-like pictures, especially using HDR technique.
