Response to Help in figuring out tech pan film

I use Tech-pan in 35mm, I rate it at ASA 100, develope it for 12:00 in Kodak SD-1, 1:1 @ 68 degrees, you may find some varition, I would suggest that you conduct your own test for PEI and Zone VIII printing, and then run a filter test with all the b/w filter to see what you get, and when you have done that, then do the same thing without filter factors, there is a big difference in the results. Regards, Pat
