P3D Re: Stereo viewfinder for a stereo camera

["Dr. George A. Themelis" <DrT-3d@xxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Peter from GouDDDa ask us to comment on the possiblity of a
stereo viewfinder for a stereo camera using cheap toy binoculars.

The idea of a stereo viewfinder for my Realist was very appealing
to me especially after I read about it in Ferwerda's book.  I
tried to make one out of cardboard until I realized the basic
problem:  How do you make the stereo viewfinder show you the
field of view of the camera?  Especially when using binoculars,
with 4x magnification, I would expect the field of view to be
very different.

So, I gave up this idea.  I understand that certain RBT cameras
have a stereo viewfinder (and so do some twin camera contraptions.)  
I have looked through an RBT stereo viewfinder but was not 
particularly impressed with what I saw.  Any comments from people
with stereo viewfinders?  Does that help in stereo composition?
