This is at the infamous ‘Tiger & Turtle’ in Duisburg, Germany. It’s a viewing platform that is built like a roller coaster. You can climb the steps on this platform (except the looping) and have a nice view on the ruhr area.
This is one of the hotspots for photographers in the german ruhr area. At sunset, blue hour and night it is full of photographers.
This PlayRaw contains a bracketing of three images at sunset. Lens was a Pentax-M 28mm F2.8. Distance between the images is 2 steps.
