Can anyone give me a bit of info on your experiances? Im thinking of getting a a fiew rolls of IR B/W film. I know there is differant light ranges that differant films absorb, so what film is best for beginners in this area? And how will light metering be affected?
 
Yeah, I can share some tips.

What kind of camera do you have? Some cameras use an IR beam to count film advancement, this is bad. Make sure yours doesent.

You need an IR filter for the lens, or a Red #a25.

You need to load it in complete darkness. same for taking it out of teh camera.

You will need bracket all of your exposures until you find out how it performs. Your light meter in your camera does not see IR. You may have to adjust up to 4 stops to compensate.

You need to develop quickly, in a metal talk or in a black plastic tank with the lights off the entire time. D-76 I beleive will work for the Kodak HighSpeed IR film.

Remember, there is a difference between Passive and Active IR this film only works with one of them.

Just for your info.
I shoot a Canon Elan 7. I dont belive that it uses ir to count negatives, but i will have to check my manual to be posative

wow, 4 stops. up or down? Is there any general ruel of thumb to use for metering IR or is it just guess untill you are able to predict it?
