"Perfect" slide mounting?

[P3D <PTWW@xxxxxxx>]

Gary Nored recently mentioned always using an alignment guide to properly
set far objects, and ignoring window consequences others might find
objectionable; Lincoln Kamm countered that he favors freedom of stereo
window choice.  How does this exchange relate (if at all) to past
debates about adjustment-free stereo projection?  (Some have proposed
that a projector be set once, using a properly mounted guide slide,
and damned be those slides that do not register 100% correctly without
adjusting the projector.)  In your response, assume that there are no
vertical or rotational errors in the mounting of the slides.  I'm just
trying to learn what the relationship is between setting the window
and adjusting the projector's controls.  (I do not have a projector,
so I cannot experiment on my own.)

Thanks,
Paul Talbot
