[Frameworks] PF2 & 7302 questions

[mstarkmcr at gmail.com]

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. 

Hope that is helpful,

Mary

An older B&W contact printer I'm using has two exposure settings, one for the ORWO stock and one for Kodak, I believe both to only affect the lamp operation voltage, one setting has a lower voltage than the other. Unfortunately it isn't terribly clear as to which of the two stocks corresponds to which setting, and can only assume that one is more light-sensitive than the other, and to go by that before running a test.
