Half a day, Astrid and I stayed with a friend at the Landscape Park Duisburg North (LaPaDu). While Astrid sketched and later came to us at the blue hour, we ran around the blast furnace 5 and I gave a photo course. The views from up there in about 70 meters high are simply exhilarating, even if we had a rather dull cloudless sky.
At the blue hour it was exciting. From the west, some light clouds came over the sky and made it interesting for our photographs. The blue accent lights on the crocodile fascinated me.
