Re: Stereo Projection adjustments

I've been talking with the celebrated "Silent Steve" Spicer off-
list about this problem. He mounts to the window. As he points
out, it's no problem if you just keep your far point separation
less than or equal to the maximum infinity separation. And as
Heartless George points out, you lose some control if you can't
mount to the window. I guess the problem I've been seeing is that
caused by people who mount to the window and ignore the separation
of the farthest points in the pair. Conversely, if a person
rigorously "mounts to infinity", even when infinity isn't there,
he ignores near points and has stuff hanging through the window in
the truncated condition. I've seen this too, at our club.
Really, my complaint at its most basic is simply that people are
ignoring the maximum separation of the farthest homologues when
mounting. It doesn't matter whether those homogues are at
infinity or not.
However, as I said before, I still think it's noticeable if the
depth separation switches around if there are no other projection
problems to mask this one.
Well, I'm still going to vote to be heartless. I'm going to have
to agree with Heartless BobH, considering his vast experience in
the field.; if he has says it's actually easier on the audience's
eyes to just leave it alone, I'm not going to argue. Maybe I
should buy/make a bunch of mounting guides for our club members so
they can check their maximum homologue separations before
projecting. Maybe I'd better check the "projectability" of my own
stereo slides now that I've been complaining about everyone
else's. 8-)
