I completely agree with that definition. I also try to get my entire scene
in focus, with the rare exception of some artistic efforts.

I've been trying to think up some kind of sliding mirror arrangement to use
with a Toshiba 3D camcorder. I *suspect* it would be very disturbing to watch,
at least for the first use, but it might be possible to become accustomed
to it. And it's bound to be interesting.

It will take some *big* mirrors - I sure hope second-surface mirrors are
good enough!

I know what you mean. :-)

Sounds great. :-) But wait and see how small you have to make your mail window
so that those parallel-view ASCII stereo pairs are viewable. :-(
