I allowed the "in the mind" portion to allow for "artistic"
effects such as hyper-ness, negatives, etc.  But I mentioned
that what you do is typical.  That is, "real life" is "it".

Well, move the camera a bit, and look at the scene with 
both eyes.  :-)  More seriously, for visualization, it
can help to have a camera with a 3D viewfinder (such as
an RBT camera).  With mine, I can see the "middle two thirds"
of the viewfinder's scene in 3D, and the other third (split
between the outer sixth's) in 2D. However in terms of this thread, 
previsualization limits due to features of specific 
equipment isn't really what I was talking about.  I'm
talking more conceptually.

Also note that with still stereo cameras, the result also
lacks "movement". One of the reasons why stereo
photos look so mystical is that adding the
z-axis makes it look so much more real than more commonly
seen photography, while at the same time, nothing is moving,
and sounds don't match.  There is a surreal effect because 
of this seemingly paradoxical situation of enhanced-realism
simultaneous with unrealistic characteristics.  I mentioned
this nice but weird feeling in some of my first postings to
this mailing list a zillion years ago (talking about my
beamsplitter 3D days).  This is one reason why 
3D Video (with sound), has the "weird feeling" completely
missing.  I like it -- but without being "mystical".  
Looks more natural.  :-)
