P3D Re: Stereo Window Demonstration

[Bruce Springsteen <bsspringsteen@xxxxxxxxx>]

Moving chips in and out behind a mask is OK, but the demonstration I like
better is to use prints and move the masks in and out - thereby actually
moving the *window*, which is the point, and not the scene, which
technically is not the same thing.  Remember that moving chips in and out
is changing the convergences of everything in the scene, as well as the
infinity separation, and creates distortions and potential divergence
issues.  Of course with slides that is the only option, because the
distance between mask apertures is fixed.

That's why I enjoy using the View Magic viewer for up-close window
demonstration.  It is easy to have a fixed separation in the images, and
move the masking for the scene in and out.  It reinforces the idea that
you are *cropping* the image to position the window.

I'm working on my own workshop demo, but Mesa is out of the question, so
have a blast, George! ;-)

PS  - Dave Kesner is right about everything.
