If you put a pair of 6x7 landscape format images side by
side, it will not be possible to fuse them into a 3D view
with any standard parallel viewer.  You would have to have
some kind of prismatic viewer.  In vertical format you
could probably view them, but there are no slide mounts
for the format.  The outside dimensions of the RMM slide
mounts are 80x132.  The largest current RMM mount aperture
size is 50x50.  I think somewhere around 57mm is the widest
horizontal aperture that could be used in most parallel
viewing MF3D viewers.  You could probably get about a 65mm
max vertical aperture while leaving enough room for the
required top and bottom borders.

Not many 3D photographers seem very enamored of the vertical
format, however.  I could have mounts made in this format
(about 57mm wide by 65mm high) if enough folks commit to
paying what it would cost.
