You might see some results on EIR with the red enhancers, perhaps in
addition to a #8 or #12 yellow, but not on HIE....enhancers are made
not to affect most of the visual range (or better: surpress it very
slightly and very evenly), they are almost digital in nature if you
look at the spectral graph. Also, I have read notes from TopShooters
(Canadian, once 'the' enhancer, site currently down....are they
still in business?) that it blocks both UV and IR rather decently, so
it might not be good with any IR film.
