Is there such a thing as an infrared exposure meter? A narrow-field one would be optimal.
I'm interested in trying some near-IR film like SFX 200 but want to be able to meter reasonably accurately how much IR of the appropriate wavelength is reflecting off the foliage so I can more accurately expose and develop the film without having to bracket several frames on a minimum of two rolls... this allows me to adjust development on the second roll.
Hmm... now that I think about it burning extra film is probably more cost-effective than a dedicated IR meter because I won't be shooting that much. None-the-less... my curiosity is up now!!
