Thomas, what I'm suggesting is that when "the camera's angle of view" matches "the viewers angle of view" (defined by print viewing distance and print size), the the print will look normal.

There are definitely limits to this, a 180 fish eye for example, but if viewing distance remains constant and print size increases a wider lenses can be used.

The flattening effect of the longer lenses that we are all so familiar with is because of the mismatch in camera angle of view vs print viewing angle.

The same math formula applies to both applications.
