Re: [photo-3d] Gary's stereo windows

[Paul Talbot <list_post@xxxxxxxxx>]

I generally agree with Allan Griffin's observation that "one-
to-one teaching is the best way by far" for teaching the stereo
window.  If I could, I would travel anywhere and everywhere in
the world to personally tutor 3d photographers on the stereo
window, but, alas, I cannot.  :-(  So I did what seemed the
next best thing: created the RMM Stereo Window Tutorial Slide
Set.  With both brief descriptions next to each slide for quick
reference, and a more detailed five page text write-up, the book
contains all the information that I try to convey in one-on-one
tutoring sessions.  Those sessions, BTW, are far easier with
suitable demo slides like those in the tutorial.  Trying to teach
the stereo window with a random slide or two that happens to be
lying around can be much more frustrating and time consuming.

I've had very good results in these one-on-one sessions--with the
right images, the concept is usually grasped in a matter of minutes
or seconds.  But a few cases are highly resistant, with the student
professing an inability to discern a difference between two very
different window examples.  Sometimes there are reasons why the
window is not seen correctly: for example, when the viewer has small
lenses like a red button, and the student cannot see all four vertical
edges of the image simultaneously.  The case of two people at our
last club meeting, however, still puzzles me.  We had several newcomers
and one long-timer have the "oh yeah, I can see that" reaction to
the demo slides, but some gave no sign of seeing the differences--
unless something was coming through the window.  They can see that,
but don't seem to understand the difference between having the subject
close to vs far from the window, or the crucial difference between
"coming through the window" and a "window violation."

I avoid going on to the "how to" details until the person has seen
demo images and had the light bulb come on.  For most students, that
takes only a few moments.  Once they understand the window it is
easy to teach the "how to."  If they don't understand it, there is
little chance of success with the how to.

David Kesner remarked about interacting with folio members who
request more details:

Do they say they don't see it?  Have they seen good demo images
that clearly have very different window settings?  I would say
don't give up until they have seen good examples and then still
cannot tell the difference.
