I remember using it, but I used it at the recommended processing time and temp from the Kodak info. (http://www.kodak.com/global/en/professional/support/techPubs/j109/j109.shtml)(posted 9515 days ago)As for exposure, I use ASA 1600 with B+W 092, ASA 400 or 800 with B+W 091, and I think ASA 100 with B+W 090 (Wrattan 25A). If you want that "bent light" effect, you have to give it +2 exposure. If I was doing a lot of that, I would use a dilute (compensating) mix of Xtol, and agitate it probably once every 60sec instead of 30sec.
