Re: Fwd: IR in darkness

[George L Smyth <GLSmyth@xxxxxxx>]

Sorry, but I don't have the answer they want, which uses the dreaded "T" word -
test.  One can bracket a few shots, remove them from the camera and develop
them.  In that way, film can be saved.  Using flash at night with infrared film
is somewhat a jump from never having tried the film at all, so perhaps this
isn't really the best place to start.
