Try shooting it around 1/25 second at f/16 using a red filter on a sunny day. Bracket around that exposure, especially since you appear to be in the mountains and I'm much closer to sea level. Give it a lot more exposure if you are shooting in the shade. (Ditto for closeups IIRC. Check the data sheet to be sure.)
I Like HC-110 dilution B for 5.5 minutes at 68F for this film.
Remember to load and unload the camera in complete darkness with this film. Also, remember to compensate for the difference in focus with IR (although some people ignore the compensation with small apertures).
As far as reciprocity, dunno. It's a crap shoot anyways. Wise thing would be to run a test.
One final thing: some modern autowinding autofocus autoexposure dx-indexing cameras have an infrared sensor inside the film chamber. This results in fogging of the infrared film and qualifies for one of those most stupid engineering awards. Be sure your camera does not have such a feature when using infrared film.

I also prefer a #29 red filter rather than a #25. You may want to try some of the orange filter too. When you are starting out try to be consistent with the filter usage and exposure to learn what works. 1/60 @ f/11 is my pivot point and then bracket in half stops.
Good luck,

nworth said:One of the recommendations for HIE is to use a Minus Blue (No. 12) filter. Many prefer this, and it makes sense. All layers in the HIE tripack are sensitive to blue, so you need to get rid of it. But the individual layes are sensitized to green, red, and infrared. Using a red filter kills the green sensitive layer (which controls the blue color in the transparency). This is often the effect you want, but sometimes not. Experiment.
