Single exposure. The Castle is, in my opinion, too hard lighted. For this reason I took this picture a few minutes earlier than usual to avoid oversaturated colors and too strong contrast at the local level. The cloning was enough intense, to remove various noise elements. I however preferred to leave the silhouettes of the people you see on the walk at the foot of the Castle.
