Slight clarification: The new film can be processed as E6 if the
recommended processing (AR6?) is not used.  You have to know in
advance which processing you will use, as the suggested starting
EI, which is normally 100, jumps to 200 for E6 processing.

Harold Baize reported shortly after the film came out that it
depolarizes light.  I later asked him about it off-list, and
he indicated he was getting inconsistent findings as to whether
it depolarizes or not.  Something to keep in mind before submitting
an EIR stereo slide for projection in front of a group--check the
image for depolarization before hand.

I believe the recommended filtration is Wratten #12.  I've heard that
the images come out monochromatic if you don't use the filter, but
don't know from first hand experience.
