T3D Re: Cardboarding? (TECH-3D digest 377)

RE: Wm. Carter's idea that "cardboarding" (cutout figures in 
planes??) results from two lenses seems bizarre to me. Does he 
imply humans see everything as cardboard figures?? I understand 
the concept in lenticular systems with not enough lenses, eg. 
Nimslo, Nishika compared to commercial systems with 10 or 
more, but this seems a 'resolution' effect.
As to clues Wm. Mortensen (a contempory of Adams) believed 
that one should have good enough gradation in a negative that a 
white sphere would be recognized as such in a planar photo just on 
the difference in brightness due to square law effect on the 
distance between surfaces of the sphere to the lens. He 
maintained that the rule of 'expose for the shadows and develop for 
the highlights' destroyed this kind of gradation!  So here is another 
clue that eye might use!
