Only question is, why bother with the SFX filter when the film is only going to react to IR anyway? I could understand that the SFX would give you a near IR look on a panchromatic film, but with film that is only sensitive to IR it seems like belt and braces. Or is it just to slow the film down? - - PHC - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
