I shot one of the rolls today, and after placing it into the player with no effect, I rewound the cassette by hand in the dark. This revealed no image on the film whatsoever. So, deciding that cannibalizing this cassette in order to discern its inner workings was better than making many repeated mistakes, I took it apart. The chemistry had dried to a very gummy consistency, and I suspect that the integral developer is completely useless. So I cut a strip from the roll and ran it through a sort of improvised HC-110 monobath, figuring that if a very high ratio of HC-110 to fixer doesn't develop it, (I mean, the stuff at Dilution A processes Tr-X in about 5 minutes...) nothing would. The developent was for roughly two minutes, and the processed film has been nearly stripped of it's emulsion, which makes sense, Polavision being a positive format. When it is light out tomorrow, I plan to shoot a roll of test footage, clip it into many short lengths, and experiment (in a less haphazard and more scientific manner...) with processing times. If anyone has, or knows someone to ask questions regarding, information about the chemistry used in the cassettes, that would be most welcome.
I've included a scan of the positives that should illustrate the relative densities of the unprocessed and processed bits of film.
