Duomo and Galleria
This photo was taken at twilight (before sunrise) in Piazza Duomo in Milan. The composition is the result of the union of three vertical pictures on panoramic head in aperture priority. For each of these three shots a double exposure was made to capture the full dynamic range. The photo you see is therefore composed of a total of six shots.
