What is the process for developing IR film?

I know you need an IR filter for digital IR photos, but for film, is IR film JUST sensitive to IR light? Or will I need a filter? Also, are the chemicals used in developing the same as for regular black and white?

Just wondering, 'cause I saw some IR film on B&H, and thought about it.

You need a filter, a #25 red works fine. I have always used regular T-max developer with good results. Kodak use to have some time information on their site, but seems like I was at 75 degrees, 6.5 minutes with 30 second intervals.

Remember IR focuses slightly off visible light. There should be a red dot on the lens which is the focus point.

thanks for the help!

oh, wait. 6.5 minutes for what kind of IR film? OR does it not change, cause I know you develop ASA100 and ASA400, etc, for longer and longer amounts of time. Is IR film all the same grain?
