perspective and asymmetrical lenses

[T3D John Bercovitz <bercov@xxxxxxxxxxx>]

I've got another try at explaining how to find where the
center of perspective is for a picture taken with an
asymmetrical lens.  I think this one is clearer than my
last attempt.  I hope it is because it's the last slide
of my lecture on perspective at NSA.  If you feel inclined,
straighten up. 8-) No, if you feel inclined, take a look at
it and let me know if it's understandable.  It's in the 
T3D web site Joel maintains for us at
