Hmmm, try it, and bracket in whole stops over a wide range with
a couple of standard scene-types that you are interested in.
Keep accurate notes. See what, uh, develops. Next roll, you will
be in good shape to try again. (Increased development can improve
the normally low-contrast highlights [of which there are a lot
with IR when shooting folliage, which turns white].) I seem to
remember setting my Nikon camera meters at 200, using Kodak HS
Infrared with a standard no. 25 filter, shooting sunlit scenes.
Remember to handle the film cartridge only in VERY low light -
I find that shaded safelight in the darkroom is OK, and gives
enough light to see to handle the film while loading/unloading
the camera (darkness is recommended, to avoid fogging the
film in the cartridge [the trap leaks IR], but.....).
Hope This Helps
