[photo-3d] Re: Spicer mounting

[Ralph Johnston/Linda Sherman <copley@xxxxxxxxxxxxxxx>]

No, these were not hyper shots, but normal RBT ones.  I just mounted another
roll and had more problems.  On one, the perfs were visible because one film
chip had slipped off the pins.  I caught it before taping.  I now am VERY
careful to check the chip outline on the spicer mount before taping.  The
perfs
should be parallel to the edge.  Thanks Dave & Paul for inputs on how to avoid
misalignment.

Mounting the hypers was a challenge and I had to retape on a few before it was
OK.

The fisheye shots came out great.  I mounted them in RBT 33mm mounts.  Not
having the coupling bars for aperture and focus is not a problem.  The lenses
are heavy, though.  (These are Zenitar 16mm f/2.8 in Pentax K mount available
from 

russianplaza@xxxxxxxxxxx 

or on e-Bay.)  Best to avoid scenes with lots of straight lines as there is
some curvature at the edges.  But how else could you cover 180 deg?
