There have been several discussions under the B&W film forum related to this film.

One: http://www.apug.org/forums/forum37/7...0-rodinal.html

It's very nice as a pan film, but costs two or three times as much as more ordinary film. I found I needed about 6 to 7 stops compensation with an IR filter of 720 nm cutoff. An 89B at about 695 might need a stop or so less. With a 760 nm, I needed around 13 stops above the reading for ISO 400. I would expect using a 25A with about 3 stops compensation will produce something, but in the end, experimentation and bracketing are the only answer. In general I seldom do portraits, I have no idea what IR does for that.

The other little tidbit -- you can't see through an IR filter, so they are a pain with an SLR!
