P3D RBT Wars!

["Lawrence A. Haines" <lhaines@xxxxxxxxxxxxxx>]

I have mistakenly misled the list on my RBT.  It has the 75mm base
lenses not 65mm.  I must have been half asleep when I said 65.  That is
why I told Dr T that I could agree with him on the 59mm  base on the
S1.  The 75mm base gives me fully utilzed film keeping film cost down.
One big advantage to me of the 75mm is that I send my film out for
development to a shop that does work for pros and I get the film back
mounted in standard full frame 35mm mounts.  The lab complained a little
in the begining since the spacing of the pictures on the role is not the
same from one picture to the next.  that meant their cutter had to be
manually set for each picture.  But they now do not complain anymore.
The full frame gives me some adjustment possibilities when I mount in
Gepe 33mm wide mounts.

I wrestled somewhat in deciding to go with the 75mm but the advantages
mentioned above convinced me.  For shots other than real close ups I
have found no visual problems using a viewer, with the slightly larger
than "Realist" base.  Actually I enjoy the very slightly enhanced
stereo.  I must say however I do not yet have much projection experience
with my new set up.  I am putting together a presentation right now
about the island I live on, using four Ektagrapihic projectors and I
will know more on this aspect later.

Getting back mounted slides is a tremendous advantage to me since I can
quickly view and pick out the ones I want to mount myself.  I store them
in thick three ring binders in plastic archival preservers made by
"Print File" P.O. Box 607638  Orlando, FL 32860.  The style nimber is
2x2-20B.  The slides are easy to put in and take out of these pages.
When I want to take a look at a bunch I just flop a page down on the
light table without even taking the slides out of the page.
