Re:Re: John SL3D Debate? ( digest 1616)

RE: I have not been getting into the details, just lurking. In this
response John B. covers half lens and views ground glass, then covers
other half and views ground glass. And declares that the two images are
different! So he got stereo out of a single lens. Maybe this is what Wm.
Carter is talkig about????
As any part of a lens will act as a whole lens, there are infinite
pairs??? The prism rf in ground glass of SLRs uses the wide open lens as
a base because of this. A huge magnifying glass used to view a flat
picture with BOTH eyes looking, will make the picture seem to be very
3D. Is any of this what Wm. Carter is using and John disputing?? BobH
