I've been told by astronmer types and other folks in the know the proper
exposure for the moon is f/11 @ 1/(film EI). The sunny 16 rule doesn't get
it so well because the moon has a low reflectance (albedo) in spite of its
bright appearance. In reality it is a dark colored piece of rock. Rock
reflects IR about the same as visible light so theres no need to make any
exposure corrections for IR reflectivity. You probably won't get anything
that looks too different from a visible light image.
If you want to really see if there are any differences betwwen the IR and
regular film response the best was to illustrate the difference is to shoot
one IR and one normal shot with the same lens. Scan them and if you can
superimpose a negative image of one onto a positive of the other. All
similar areas should mostly cancel out, leaving the differences behind.
Should be and interesting image. It'd be fun to see such a processed image
of more earthly items.
