Re: [Frameworks] PF2 & 7302 questions
Hey Chris, I've used a lot of PF2 and for daylight I've rated it at ISO 4 whereas in tungsten or on a contact printer I would shoot for something beneath ISO1. Whatever is a higher voltage on your contact printer probably will work better for the PF2 cause it's slow. On a JK with the LED upgrade I had to expose each frame anywhere between 1-4 seconds. It took an extremely long time! And yes, I've mostly used Dektol or D19 to process which creates pretty hi contrast images particularly after duplicating a couple times over or when contact printing from an original. best of luck!

Re: [Frameworks] PF2 & 7302 questions
Best to do a clip-test as different batches of 7302 can have variable speeds.

Re: [Frameworks] PF2 & 7302 questions
Hi Chris, I have worked with both these stocks - i prefer pf2 which i find to be extremely robust in terms of tolerance of light and to create high contrast images. I don’t know about the developer you are using as i have used dektol and mostly rodinal. 7302 may well be the one that needs the lower voltage? I have used that before too and found it similar to pf2. I can’t remember which was more sensitive. Both stocks to my knowledge are fine with dark room redlight and like i said pf2 can tolerate a quite a lot of light.
