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-)
