Stereo Window - Window to the world?

[P3D Bill C Walton <bill3dbw3d@xxxxxxxx>]

WOW what a mass on information about the 
stereo window! Most enjoyable, except I did 
not see (or maybe I didn't read) very much 
in connection with print makers and the 
stereo window.  

I know there are a few print makers in the group,
maybe some of them will participate after I get 
it started.

We print makers have the same option as slide 
makers as far as moving the objects in the 
scene closer or farther away from the window, by 
moving the "chips" closer together or farther apart.
But once you start this process it may require some 
radical trimming to maintain the correct stereo 
window.  Closeups  are sometimes trimmed to 
little images to maintain the correct window.

Someone mentioned "I always want to tell him to 
move his subject closer to the window"  We print makers
have that option by enlarging the print. Objects in the 
background can be brought closer to the window, or even 
through the window, if desired , while still maintaining 
the correct stereo window.  Some folks say that enlarging
"flattens " the stereo effect, but I haven't found that to be a problem.
I did get a comment once on a house stereograph that I enlarged 
to being the house closer to the window of "The house is to close
to the window".  Another time I was making stereographs of 10
people, one at a time, trying to use a different background for each 
one. I was to far away from one man and his image was quite 
small.  I figured I could enlarge it enough to match the other 
folks.  I did, but that did not work out at all because it not only 
made him bigger, it brought him through the window !  Live and 
learn.

Stereo window reversal is sometimes a problem for print makers
and we try to avoid that.  Many of us belong to the SSA which means 
our efforts are subject to scrutiny by folks who have been doing 
this for a long time.  Paul Wing comes to mind since he has been 
making stereographs since the mid 1940s.  He never lets a window
reversal or a to wide separation go by without commenting.  Of 
course this helps the stereographer, if he /she will pay attention.
