How do traditional negative cameras rewind?

Pay special attention when loading the film, and be careful to touch the shutter curtain. Be careful. It will be O when touched, hehe! ! Don't have water and dust on your hands, so as not to get it into the camera, and then you must change it in a clean place. You must be careful when there is dust in the air. Unless you have special requirements, don't change the negative in a dusty place, and then it is best not to have strong light, so you must breathe lightly and be careful when your saliva gets on the machine! Basically, that's all. Pay little attention to rewinding. Just pay attention to rewinding time. Generally, you should know how long it takes to rewind a film. Then you'd better remember the sound of rewinding the film. Remember the time and sound to prevent the film from having problems during rewinding and the film is not loaded properly. Oh, pay attention when shooting. Pay attention to the sound when the camera is shooting, which will help you take pictures! As for the reverse film, the title is also poured in. That's nothing. It should be poured in, but it's not right to pour it in. If there are too many negatives left outside, it will be exposed. So don't think about the title. Just pour it in! !
