How comes that most panoramas are horizontal?
I believe, vertical panoramas can provide a much more unusual perspective on the world.
I shot this panorama, for example, near Schloss Rosenstein in Stuttgart, Germany. A small path led through a green park down to a kind of viewing platform. From there you have a great view at… railway tracks and a cemented landscape. A beautiful contrast which is emphasized by the “falling” view on the world of the vertical panorama.
