I haven’t even notice, while I was taking this panorama, that half of the image is completely dark, while the second is quite bright. It’s actually a little strange, that the street right next to the water is not lit at all. But since you can see from the amount of lights on the Charles bridge, they probably decided not to bother with it.
This is a two tile panorama, each tile from 3 exposures. Panorama combined using PTgui, HDR created in Oloneo Photoengine, finished in Photoshop.
