[MF3D.FORUM:670] Re: Stereo Resolution -- Increased by the Brain ??

["Oleg Vorobyoff" <olegv@xxxxxxxxxxxxx>]

I'd give the subject question a resounding yes, and add that it applies to
viewing practically anything in any manner.  All you have to do to confirm the
effect is look at anything flat with two eyes after having looked at it with
one.

Matt's last question is more interesting.  The bottom line is that with stereo
you can often get away with with worse lenses and image presentation methods
than you can with 2D photography.  The idea of relaxing standards seems
downright abhorrent, though.  I think that may be one reason I personally cannot
get too excited by stereo cards.  They do depend on stereo to mask the low
resolution (under viewer magnification) of printing techniques employed.

What is really intriguing to me is whether 3D could be used to increase the
apparent resolution of 2D imagery.  I know that duplicate non-stereo slides look
sharper and more vibrant in a 3D viewer than one of the slides viewed in any
way.  This might be a means of squeezing MF quality out of 35mm equipment, and
LF quality out of MF.
