#187063 - That's why they have the features on those view cameras
Responding to: Jez Smith's previous message
I was once a photography junkie, and even went so far as to buy what was then (1960's) a full-featured view camera, with which I endeavored to take pictures of old tall buildings in ancient venues around Europe. These cameras use a lens with a large illumination circle and raise its optical center above the center of the plate/film center in order to realign the otherwise converging verticals. With a short enough focal length with a sufficiently large illumination circle, you can get an entire tall building to look properly aligned, in terms of its vertical lines, though you still get the "street view", in that you see the ledges from the underside.

I don't believe that's what's going on in this case.
