That's what I had assumed, but on the roll I tested this with, the shots
from outdoors with no flash were somewhat underexposed, but still usable
(actually, they were underdeveloped, not underexposedI've since learned to
drastically increase the recommended development times for XTOL with HIE),
while the indoor flash pictures were extremely underexposed (or well
underexposed in addition to being underdeveloped like the rest of the
roll). Maybe I should rate it at ISO 50 or something... I guess a test roll
is probably the only way, since everybody does IR a bit differently (more
so than even b&w).
