Brian:

That is all true, but there is a -big- difference between doing
a "cha-cha" shot with a Pentax 6x7, and doing it in 4x5, where
you need to physically move the tripod, slide in the dark slide,
flop the film holder, take out the darkslide, and re-cock and
fire the shutter, all before anything moves in the scene!

I've done this with a 4x5 in the past, the best way is if you
can find a road or sidewalk, so at least you can slide the
camera/tripod combo over easily.


On another note, my 8x10 camera has a large enough lens board
to hold two lenses (if not -too- large). Some long time ago
(Greg and Bob??) got us a good deal on matched Tominon 127mm
lenses, which I got two of. (P.S. - any reports of how good
the quality was??)

At any rate, they cover 4x5, so with two mounted side-by-side
on a blank 8x10 lensboard, I could get two 4x5" stereo pairs
on an 8x10 sheet of film.

Just need a simple septum, and one of Jay Bender's "panoramic"
darkslides (http://www.benderphoto.com/4x10pa.htm) or equivalent.

'Course, I'd need to set up my enlarger as an "ensmaller"...  ;)
