P3D Window Cleaning

[Bob_Maxey@xxxxxxxxxxxx]

>>RM, I don't think you understand the concept of the stereo window.
Or the violation of it.  This is very important for good stereo
mounting.  I suggest that you review past photo-3d digests or attend
a mounting workshop.  I'd love to explain the concept but I have done
it too many times and don't have time to rewrite or dig things up.
Also, this is better explained by doing things (like shifting the
chips or prints under a fixed mask) than talking about it.


Actually, RM (With an Indigent Stare) understands it very well indeed. I
think from reading various posts about the subject, that others might not.
Or at least might have a different idea. That is why I asked the question.

Please correct me if I am wrong, but here is how I understand and explain
the Stereo Window:

Since a stereo photograph does not completely cover the entire field of
vision we humans are normally used to, this led to the concept of the
Stereo Window. Stereo photographs look like we are looking through a window
at a scene. This window can be controlled by manipulating the film chips,
and objects in the scene can be controlled as to their placement within the
Stereo Window.

This works with imaging techniques such as Vectographs, where alignment of
the matrices can control what objects appear behind or through the Stereo
Window. Regardless of the process, the concepts are the same, excluding
holography.

If an object touches or "Breaks" the frame, parts of the object will appear
in front of the window, confusing the viewer. A hand holding an object that
does not touch the frame comes out of the window, and everything looks good
unless part of the object touches the frame. For most people, objects must
be mounted so the nearest object is at or behind the Stereo Window.

If you desire to have some objects "coming at you", through the window, it
is imperative that anything located at the edge of the slide mount does not
protrude through the window.

Like I said, I think I understand this stuff, but it seems to me there
needs to be clarification so everyone knows it as well.

Cheers,

RM
