Re: "Perfect" slide mounting?

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

I agree with Ken Luker and his concern regarding the exclusion of cardboard
mounted slides from NSA.  "Historically", mounting slides in cardboard
mounts has been associated with "beginners" or "lack of experience", that
would lead to less accurate mounting.  But it is true that the mount is no
assurance of precision and that it is possible for a person, with some
practice, to master the use of cardboard with excellent results.  For the
viewer and for projection in up to 70" screens, cardboard mounts are
sufficiently accurate.  I do not know what happens when using the large NSA
projection screens and the RBT or Brackett Dissolver projectors used in
these conventions.  Now, without any aluminum mounts in the market, perhaps
NSA can revisit this policy?  IMO, it is not worth remounting 150 slides
just for an NSA program.
