Sandy,
I used a lot of BPF a couple years ago and got good results with the same
reciprocity compensation as TXT. In the 1-8 second range that means one full
stop more than the indication. By an indicated 30 seconds you want at least
two minutes, or go have a cup of coffee. Since BPF is reluctant to gain
contrast, especially to levels wanted for alt processes, no reduction of
development time seems necessary.---Carl
