P3D Pulfrich and one-eyed depth perception

[Michael _ Kaplan <mkaplan@xxxxxxxxxxx>]

>Pulfrich, incidentally, never saw the illusion himself. 

The short biography was fascinating. However, I wouldn't necessarily jump
to that conclusion. I'm wondering whether Pulfrich had *always* been blind
in one eye, or was it a developed condition? Some while back, I posted
results of informal experiments I had done viewing lenticular prints with
only one eye. By rotating the prints along a vertical axis and delivering
L and R images sequentially to only one eye, the brain (at least, *my*
brain) could assemble a 3-D image with full depth. Whether this is a
learned rather than unconscious operation, I don't know. However, I
suspect Pulfrich was fully able to see his "effect," and referred to his
assistants only for confirmation of what he was seeing with one eye. And I
also suspect viewers could be trained to see horizontal-scan shots
3-dimensionally *without* the Pulfrich glasses. 2 years ago I mentioned
*almost* being able to do this while watching IMAX HD (48 fps).
