Re: R: [photo-3d] Digest Number 234

Sergio,

The arrangement of mirrors and prism in the Tri-Delta actually rotate each 
image by 90 degrees on film.  The two images are top to top, with the 
"seam" between them running vertically through the frame.  So, each image 
is 18mm tall and 24mm wide.  When cut, the perforations will be on the left 
and right edges of each image, not at the top and bottom.

Currently, the only way to view Tri-Delta slides is through a Tri-Delta 
viewer or projection adapter.  Being able to cut the frames and re-mount in 
41mm x 101mm mounts would be a great benefit.
