If you compose a scene with a depth range from 7ft to
infinity and use 65mm stereo base then you can get both.
But when you start with 120mm stereo base then it is
harder on the realism front.

This particular effect (miniaturization) does not exist if you
maintain 65mm base.  But the other effects I mentioned might 
be noticed.

>Is the cardboard cut out look also as a result of hyper stereo?

No, in one sense it is the opposite.  It is noticed if you use 
a long FL lens and maintain a regular base.  You see this
when you look through binoculars.  Increasing the stereo base
tends to alleviate the cardboard cutout effect.

For this particular shot (my first Realist picture!) I asked
my wife to pose in front of the house.  She was rather stiff
posing head-on to the camera.  I might have lowered the angle
of view so there were three depth levels: My wife, a tree and
the apartment building the back.  This created the effect.
If I had posed my wife sideways or had used a higher angle
of view (to include the ground) things would have been better.
But I was also more sensitive to the effect, a healthy
sign :), comparing the stereo slide to the real life.  I have 
now become totally insensitive to the cardboard cutout
effect when using a standard stereo camera.
