Ah, it just keeps getting more interesting.(posted 8467 days ago)Further reading on Usenet yielded using a meter and a light board to read the negatives (unexposed developed,and a series exposed for Zone I at different apertures). Find the one that reads rougly 1/3 stop more dense than the unexposed sheet, and bingo, there's your 0.1 density negative.
As for Ifosol-S, I didn't realize it goes off that fast.
What developer would you recommend with HP5+? I've also used D-76 - do you have any other suggestions?
Thanks.
