This is something I shot this week-end on a Mamiya 645. It didn't quite come out like I had hoped and all the roll was equally effected.
There is an air bubble on the fence; disregard.
The film base had a purple hue and the pattern ran through the frames. The chemistry is fresh (3 days old) and the previous films (3 fuji sup x-tra 400) were perfect.
The film was out of the fridge for 12 hrs before I shot it and has been in the fridge since I bought it. I have had 2 rolls from this box of 5 developed without indecent 6 months ago. Exp Jul 2012
Moisture problem, looks like. I notice you're in Canada, and it's mid-November. Something tells me being out of the refrigerator for 12 hours in Canada in November, is there much difference between being inside a refrigerator and outside it?
I posted my answer, the a new screen with Polyglot's answer was there. Looks like a good answer. But no matter what the answer, sounds like some supplies need to be gotten rid of, and new ones bought. Could be a pricey problem to pin down.
As a control what you send one of the rolls out to a lab and have them do it, and then from the same batch you have your own films and compare them if the lab comes out just fine then you know there's a problem with your chemistry.
