OK, I think I understand so the 92 filter is best as I risk not exposing the film at all with the 93 because it begins at 800nm and some of the Rollei film doesn't even reach that high. OK, and I will set the meter to around 6 ISO and then bracket +/- one stop on either side (3 ISO and 12 ISO) and hope for the best haha. I was doing something similar when I was shooting my 1947 expired Verichrome... that was also 0.75 as an estimate of the EI I would have to use based on age... haha
