Does it matter UNTIL it's projected?  When it's projected, doesn't
it then fall out the McKay's category of "not being able to see it"?

Must all slides be projectable?

Taken with enough resolution, there is no such thing as perfection in
anything, even in the best work done by the worlds most perfect
perfectioninst.  What defines 'good enough".  Might not the definition
of "not making any difference if better" be sufficient?  For stereo
slides (for instance), might not "if you can't see it, then it's okay"
be the pragmatic position to take for adequacy?  

I think McKay's position is quite reasonable and a good one.  When
something has potential for causing a problem, then it isn't a
fault, but a potential fault.  If I mount a slide for 
a hand viewer, and it looks just fine (but wouldn't project well)
then it isn't improperly mounted -- it's just viewer mounted.  Until
the time that I want to project it, it's perfectly okay.  If I can't 
see it (or otherwise detect some problem with usage) then the problem
isn't there, all that's there is a potential problem.

Back to the practical world, what does this mean?  It means that one
can have their realist slides mounted by Kodak for the little Kodak
charges and feel guilt free, even if they aren't projectable.  If they
look good in a viewer, then they *are* good.

One assumption that is often used is that all slides will be projected,
while I suspect much less than half are.  I'd guess substantially less
than half.

P.S. - Even with a "perfectly" mounted for projection slide, it still can't
       be error free.  How can it be error free when judging by the recent 
       threads it can't even be be decided as to what perfectly "right" is.  :-)
