This is probably a dumb question but can you load black leader film into your camera (in my case bolex).
Just wanted to practice loading my camera in the dark but need a dummy reel. Is it better to just buy a dummy reel thats been shot on already or is black leader film fine?
Sorry should've been more specific, i mean for example, changing the 133 angle to lets say 180. Just wondering if its possible to mod it to a higher shutter degree angle.
