Ok...a couple of questions:

My Pyrocat MC turns lavender shortly after I mix it. Is this normal?

I'm getting mottled staining. I think this may be from the period of time the emulsion is exposed to air when I drain the developer and add the stop....and maybe due also to inadequate fixing. Thoughts?

I'm about to run another test with a change of process...taking the film from the developer straight to a stop tank with only a couple of seconds exposure to the air.
