Do you know of any publicly accessible place in Cologne where I can photograph Cologne Cathedral's entire west facade in a single frame? See examples below.
The Cathedral's west square is not a good place for that because of the angle which creates very conspicuous perspective distortion and requires a very wide lens (10-20 mm would barely suffice).
Regarding lens and camera: I have an 18-200 mm Nikkor lens and a "crop sensor" Nikkon D7100.
The Colonium TV tower could be a very good candidate but as of 2023, it is closed to the public. There also might be buildings with publicly accessible roofs with a view of the cathedral's west facade, but I don't know of them, hence, my question.
