This idea that you and others have mentioned might well accomplish what I'm
after.  Perhaps not  by setting the sharp point (plane) "to infinity," but
however far (in z) my scene happens to extend to.  Anything past that
point wouldn't matter. Embarassed to say that such an obvious solution
hadn't occured to me. :-( The only small downside to this that I can think
of is not being able to set a point (plane) close to the camera where the
blurriness should cease; it's all up the aperature setting in this case. But
hey, I'll try it--maybe it will work just fine!

That's true. :-)

Yes--and binocular vision adds complexity to the issue as well--two
overlapping "images" that the ol' brain has to make sense of.

Thanks for the reply!
