Only shot a couple of rolls of HIE so far. But can recommend Kodak Xtol 1:1 to develop it. I used the times from the Kodak J-109 Xtol publication:
I think I used the times for the 0.65 contrast index (CI). Also, I took my photo teacher's advice and used a red #25 filter. Set the camera to F/11 at 1/250th sec and bang away. I also bracketed the speed below at 1/125 and above at 1/500. But more often than not the original 1/250th sec exposure was my favorite. Don't bother with the meter sice you really can't meter infrared wavelength anyway. Hence the bracketing... ;-)
A good book on the subject is "Infrared Photography Handbook" by Laurie White. She has some good recommendations for starting out like the red filter one above. Only three problems with HIE so far. One is that you will get "hotspots" or large differences between shade and sun. So a lot of burning in or dodging to make a decent print may be needed. Second is that HIE is only avail in 35mm (135) and in 150ft length of 70mm arial film sizes. No 120, 220 or sheet film anymore... :-( It's also very expen$ive at $11.00 at B&H the last time I bought a few. Last but not least you need to be extra careful not to expose the canister to light. Infrared can easily go through the felt light trap on the canister and fog your film. Either bring a film changing bag with you if you want to change your roll in the field or leave the film in the camera and wait until you get home or to a darkroom. A few shots I have with HIE are at:
