I am a total beginner and my Pentax K 1000 has jammed a few times. Being the noob I am I ripped the film from the canister. I have the film rolls but the film itself is not in the canister. Can I still develop the film?
Film works by changing when exposed to light. If you have exposed the film to light, then any information it captured will be lost as the film will have been completely over-exposed and washed out. If you did it in complete darkness or, if it's orthochromatic, limited spectrum of light to which the film isn't sensitive (like the red lights in a dark room) then you'd be ok, but it doesn't sound like that's the case here.
If you've done this in absolute darkness and kept the film in absolute darkness: Yes, absolutely.
If it received some light: no.
