I am going to process a 126 cassette with Kodak Gold 100 film in it for a friend. I have tried to twist both ends of the cassette trying to crack it open with no success. I may have to use a little more brutal force with a screw driver blade to open it. I have the film already rolled all the way into one end. I noticed that the film has a back paper rolling along with the film. So I am assuming the film is wrapped in the back paper now. Is it safe to open the cassette in room light now? The film is actually the same as 35 mm film. I can process it with a 35 mm reel with my Jobo processor.
