P3D Super-hyper stereo: please help

[Dogbreath <hopi@xxxxxxxxxx>]

Hi.

When attempting super-hyper stereo, should your camera pivot (pan) at all
between exposures? Certainly, when I use my sliding rail, the camera does
not pivot, and so I thought I should apply that same principle when
branching out to a base of 30'. However, I quickly discovered that
stretching the base that much *without* pivoting the camera even a little
made it rather difficult to keep my subject (a tall building some 1000'
away) in the frame. I realize that if I were to pivot the camera to the
extent that a distant point on the horizon resided on the same point on the
ground glass in both exposures, most of the stereo effect would be negated.
However, perhaps there's a comprimise to found somewhere. What is the
accepted practice for super-hyper stereo?

Thanks for your time.
