Response to use of non-hardening fixer w/PMK ?

Basically, you want to avoid acid because it removes the stain. Most hardening fixers are acidic. So, if you use a fixer without the hardener and acid, you will be fine. I would suggest an alkaline fixer (you can skip the post fix bath in the used developer which is otherwise required to induce and intensify the stain). I can see no problem with using pyro to develop the Maco IR film. Cheers, DJ
