RE: art and freeviewing sausages

I've been free-viewing for ten years, doing, among other things, geologic
interpretations from aerial photographs.  It takes a little practice in the
beginning, but it gets easier.  To practice you don't even need a
stereopair.  My opthamologist tells me it is good exercise as well.

One method of practice is to hold your index fingers tip to tip, about a
half inch gap between them, nails away from you and 12-15 inches or so in
front of your face.  Look beyond your fingers and focus on a smallish
object in the background...a Vienna sausage should appear beteen the tips
of your fingers, do not eat it.  The tough part is to bring the little
sausage into sharp focus while your eyes are still converged on the object
in the background.  Practice 5 minutes a day for a week, try it on a stereo
pair, and you'll probably have it.  People with strong right- or
left-dominance may have a hard time with it.

I find that cross-eyed viewing of stereopairs on a computer monitor makes
for smaller images because the ray path is slightly longer.  I suppose I
could scoot up to the screen but even so the images seem a little harder to
focus.  I can, however, see advantages in cross-eyed viewing.  The
separation between images is not as critical, for example free-viewing
twins...hmm.

Now the question:  I bought a Realist and have been shooting 3D since about
May.  I made the 'mistake' of loading print film for my first roll.  I took
it to a one-hour photo shop, and I told them that the film was not suitable
for the standard 3x5...[no problem they said]...I came back and the prints
were fairly well trashed, cut in all sorts of places, and the color balance
was completely off between ones I was able to salvage.  Does anyone out
there in cyberland shoot prints with his or her Realist and how do you get
people to process and print color print film correctly?
