That is such a beautiful place. I visited in 2010. My hotel room had a great view of the harbor and parliament building. I took some pictures at sunset. I liked the harbor picture so well that I printed it out and had it framed.
As I look at the framed print of the harbor, I think the lack of sharpness gives it additional charm. It is like a painting.
I might think to look up the metadata. It suspect that the shutter speed was slower than what was needed for hand holding. Even with my G5X II these days, the stabilization and the greater tolerance for higher ISOs would have taken care of it. I took good pictures with it after dark of Venice from my balcony on a moving ship handheld.
