Rijksmuseum Amsterdam at night photographed from the pond in Museum Square. Because it was windless and the water level was very low, the pond was a perfect mirror.
The letters "I amsterdam" betray that this photo is already a bit older.
If you look closely at the photo, you get the feeling that something is not right. And that's right. Do you see what it is? Some people didn't see it after an hour.... The fastest was an architect. He could tell after two seconds exactly what manipulation(s) I had done. (Feel free to contact me if you can't figure it out.)
