This is a very easy tipster! Why can I say it's easy? Because you'll get this kind of crazy results without even camera!
So this story, one day when I was shooting something interesting, and I think I even if I got my picture that I wanted, but when I’m about to rewind my film and load a new roll then unexpectedly, I was surprised seeing a beautiful girl whom I want to take a photograph of, I just then stopped rewinding and just proceeded to shoot with it, without really thinking what will happen to my film roll. I was a bit annoyed at first that it should happen that way, but when I finally saw the results like that – I was so amazed with what happened with my shots!
