I presume Tim used parallel lenses, and is concerned about the resulting
areas on each chip which have no homologues on the other.  In that case,
a small amount of masking will be required, which as Vince points out can
be done by the choice of mount.  Even the window of an RBT "Full-frame"
mount is only 33mm wide, to give some latitude for window adjustment of
a 36mm-wide chip.  I would think that the 7-perf mount should give adequate
masking.

I use a variety of mount widths on my full-frame images.  The additional
flexability of being able to crop an image at mount time is wonderful.  In
some cases I have been able to save an otherwise-ruined image by mounting
in a Realist (5-p) mount, when a head or otherwise-unwanted object managed
to sneak into frame and cause a window violation without my noticing at the
time.  You can also center a subject in a 5-p mount which wasn't originally
centered on the 8-p chip.  When going to this extreme, some trimming of the
film chip may be necessary (but desirable).
