I don't think I have any, but I have seen a DrT slide that uses a
window violation to great effect.  He can describe it for us, or
with his permission I can.

Because you "never say 'never'" and you "never say 'always'?"  ;-)

Was a distinction made between the vertical and horizontal edges?
Vertical edge violations are far more problematic than horizontal
edge violations.

For vertical edge violations, you might choose to keep the violation
rather than cause some other ill effect like too much far point
separation when the chips are pushed farther apart.  You could get
away with this if you are doing your own projection and not allowing
the window frame to appear on screen, as someone here suggested.
(That would really be a form of cropping, which is the better
solution anyway.)  Or if you have an image that is very special to
you for other reasons, you might try to get away with a small
window violation.  I have a shot that I love that I took on one
of my first rolls, before I knew I was supposed to keep the near
points 7 feet away.  The violating object is black and dimly lit,
and in an RBT mount with the black facing forward, it takes a
careful observer to realize there is even a violation.  So I
don't correct it.

People have widely varying sensitivities to proper mounting.  I
suspect that Bob A. could point out quite a few mounting problems
that most of us overlook.
