Tips to use Ektachrome IR film?

[SolaresLarrave]

I wound up with six rolls of the stuff, bought from a photonetter. It's expired and turned out to be cheap, and I bought it because I've seen shots with the film and liked them.

However, besides rating it at ISO 200, using an orange filter, focusing a bit off (fortunately, my lenses have the infrared focusing marks), loading it in the dark and finding a lab where they'll develop it by hand and not through a machine (it's E6 chemistry), is there anything else to learn? Experiences with it? Shots to remember? What effects does it have, say, on foliage and skies?

Thanks a lot in advance!
