That elusive term: "Perspective"

[Heroique]

Most of the discussion here is like that--using the word "perspective" in different ways.

Perhaps we’re divided into “broad-perspectivists” (who include line convergence in the term), and “strict-perspectivists” (who wouldn't).

After the insights here, I'm in the former group – probably the minority one.

I considered proposing that perspective is completely determined by the position of the lens (the front nodal point in particular) and depends on nothing else.

A quick question for the technicians – does front axial swing (or tilt) change the position of the lens’ front nodal point?
