I am brand new to film photography in that this is my first experience using a completely manual camera. The only camera I had prior was an old Vivitar 35mm point and shoot. Anyway, I bought a used Fujica manual camera for a B/W Photography class. The film loads fine (at least it appears to since I feel tension when advancing and can see the wheel turn on top of the camera). The problem arises when I attempt to rewind a roll (this has happened a couple of times). I press the film release, go to rewind in the direction of the little arrow and I feel a lot of tension and then SNAP, the film breaks. I'm hoping to salvage my latest roll (at least the majority) because I opened the back a crack, saw that it was broken and shut the back. The film is not expired either. Does anyone have any advice or ideas as to why my film won't rewind?
