"This photo was taken on April 2003. It was a nice morning and I had just woken up to drink some coffee with my parents and sister. I took out my new digital camera and took two pictures of them before heading back to my apartment. When I first looked at the picture I was in astonishment because there, where my dad put a plastic for a new photo, was a reflection of a cathedral in it."
Close up of incredible detail!
There is some amazing detail in the cathedral image! And to have the last supper figurine in the foreground just adds to the majesty and mystique.
IMO it is highly unlikely to be a reflection..
