Re: Dual camera convergence points

["John O. Merritt" <JOMERRITT@xxxxxxxxxxx>]

Maybe someone like John B can tell us if the keystoning created by
toeing-in the pair of cameras could be corrected by toeing-in the
pair of slide projectors (or video projectors, for video cameras)


While toeing-in the projectors would make their two "lighted rectangle"
formats into equal-but-opposite trapezoids, so the formats would not
match, would the stereo space model then become undistorted within their
common overlap areas?

Is keystoning with cameras a function of distance from the objects in the
scene, but with projectors the keystoning is simply a function of distance
from the screen, thus making an over-correction for far scene objects and
an undercorrection for objects that were close to the cameras?
