I remember reading about this on a forum here but I can not find it. I'm reading another thread here on APUG with a lot of interest about near IR film and saw some very interesting samples taken with Foma 35mm film. One of the samples was shot at IE 1.5. Doing a lot of research on the internet I've been able to determine that with the lowest ISO setting on my camera (25) and the exposure compensation at +2, I should be at the IE equivalent of 6 (right?). From there its aperture settings, so what settings get me below 6 and what would the IE be with each F/stop?
