I believe I was the one who used the term perspective.  To me it seems clear that different focal length lenses can alter the perspective in an image.  It, therefore, seemed clear that plugin was wrong.  Intuitively I just knew plugin was wrong.  Unfortunately I am the one who was wrong and my intuitive understanding of the issue was wrong.  A little online research clearly shows that perspective does not vary with the focal length of the lens but the variation is due to the position of the camera in relation to the objects.

Certainly wide and ultrawide lenses are powerful tools, but they do not alter true perspective.

Kind of you to say that - thanks!  FWIW, as I said I understand why so many people fall into that trap.  We hear constantly about using long or short lenses to alter perspective, and in practice it is not so far off, as we tend to alter subject distance based on lens selection too, so the connection seems intuitive. This is just one of those cases where what seems so straightforward happens to be misleading.
