Response to ISO Rating and dev times for Kodak High Speed Infrared

Andrew, be sure you bracket a LOT. I have used infrared sporadically for the least twelve years, and now find that for me an EI of 1000 just works fine. I know, I know, nobody else talks about that high of an EI. I live in Florida, so the sun/light there might have something to do with it.

I develop the film in Sprint 2:8. I used to give my film an EI of 400, but the negatives just came out too dense.

There are a couple of good books out on using infrared film, can't remember their title. If you go to amazon you can probably find them.

Cheers,

chris
