Infrared B&W Photography

[neildmitchell]

I picked up 2 rolls of IR film today, along with a Hoya IR 72 filter.
1) Macophot IR820c (100 ISO)
2) Kodak HIE (High Speed, but no set. ISO )

I already shot the Maco, any tips on the Kodak since ISO is unknow, and Kodak doesnt know (Checked them already). Im scared on screwing up the Kodak, it was twice the price of the Maco.

I don't like to see postings with no replies, when you've asked such a reasonable question, so--

IMO the answer is no one knows the ISO value of that film, and the practical solution is bracket exposures by many stops. Here are a couple of slightly useful url's. It's to play with, after all!

Have you shot it already? What results?
