[High score] The rewind problem of traditional SLR cameras?

Dude, it's actually not that much trouble to roll it up and rewind it.

Be sure to pay attention to whether the film is attached properly when rewinding. If you don't stick the film, the film won't move when you rewind it, so that except for the first one, which is completely photosensitive (basically severely overexposed), everything else is not photosensitive, that is to say, it is not used; When rewinding, be careful that the rear compartment must not be opened. Generally, it can only be opened when the guide rod is fully pulled up (I have encountered many cases where the rear bin is opened before the guide roller). Your machine is fully mechanical, and it has readings during normal film passing, and the film winding motor is also rotating. The reading changes when the film is guided, and the "resistance" of the motor can be clearly felt when the film is guided. Once the film is guided and separated from the film winding motor, neither the reading nor the film winding motor will move, and then the film winding will basically reach the same situation as when the film is wound.

Generally speaking, to be on the safe side, it is better to guide all the finished rolls back to the warehouse. First, it is safe, and second, it is easy to distinguish which products are finished. As for how to keep or pull out the title, it can actually be pulled out with a clip. If there is nothing, you can also pull out the title with waste pieces. I won't say this here. You have to do it yourself, and there are risks.

If you have any questions, we can discuss them together. Good luck! :)
