But the film records only what the *camera* sees, with its
parallel-gazing lenses. What the camera sees and records is different
than what the human being sees. What the eyes see when they converge on
the recorded image is different than what they saw in real-life. It's
what I call "convergence disparity."

Right. That's why I put non-ortho in 'quotes'. A taking lens is
'non-ortho' only related to a specific viewer. My question, though,
remains unanswered ...
