on a TLR type stereo camera?

Line each LP filter up using their orientation marks?

Forget it or go with twin MF SLRs?

Do you mean one with a viewing lens separate from the taking
lenses? Just about every film-based stereo meets that standard.

I use a large (4x4 or 5x5) sheet of polarizing material held
in front of all of the lenses. It works on all of my stereo
cameras. I'm guaranteed to get the same orientation for all
the lenses.

No concern about glare or optical quality?

Glare, yes. when I do this, it is only on tripod shots and I
try to position my body to cast a shadow on the filter.

Optical quality, no. My filter material is so close to the
lens that it is totally out of focus. It may be causing some
distortion in the shapes, but I haven't been able to detect it.

I think I paid $2 each for a handful of these pola-material
end-cuts from Surplus Shed a few years ago. They are cheap,
and a little scratched but they seem to do what I need.
