I wanted to share this information from Kodak.
If you process Tmax400 with XTOL and read F-4043, on page 8 there is a correction factor chart. However, data for XTOL is missing. I started this research because I use condenser type enlarger, and correction "to the left" is necessary, according to a statement on page 3 and 8.
So, I asked Kodak and here's a clip from an e-mail reply.
--------------------------
For TMAX 400
Relative Contrast
Dev Temp Dil -20% Norm +20% +40%
XTOL 75F Full 0.63 0.79 0.95 1.10
XTOL 68F Full 0.80 1.00 1.20 1.40
XTOL 75F 1:1 0.59 0.74 0.89 1.04
XTOL 68F 1:1 0.80 1.00 1.20 1.40
--------------------------
I hope this is useful to someone.
