Whew! I took 2 weeks off at Christmas, and I just now got caught up with
photo-3d.

Anyway, this is something I hadn't considered with the mounting jig. The
problem is that the jig depends on the film image TOP (or BOTTOM) being a
certain distance (calibratable in the jig) from the edge of the film. That works
fine for 6x6, but for 6x4.5 the LEFT or RIGHT edge of the image is the one
that is a predictable distance from the edge of the film, and the TOP or BOTTOM
edge depend on where you cut the film between the images.

Make sense? It's due to the different orientation of 6x4.5 (rotated 90 degrees)
from other 120 film formats.

I suggested to Dennis that, if he could find a film cutter that handles 120
film, a way to get around it would be to scribe a line on the cutter where
the edge of the frame should be placed. That would get around variations
in inter-frame spacing.

So, are there 120 film cutters available???
