:-)  Yes, I forgot it!  I told Jim, I should have brought the Lewis
achromat stereoscope with me!

This brings two issues in my mind:

1. What effect does the quality of the viewing instrument have, when
   judging stereo cards?  Clearly, a different impression will be
   formed in the judge's mind if an achromatic stereoscope is used,
   rather than a Holmes' viewer which might also be blocking
   part of the image at the edges, might not work well with eye
   glass wearers, etc.

2. Assuming that you see a stereo card that looks very good in 2d,
   excellent composition, saturated colors, etc., and then, when
   you view it in 3d in a good stereoscope, notice the lack of 
   sharpness due to printing.  To me, this is a turnoff, especially
   for a scenic view.  How much penalty does the judge impose in
   this case?
