We used a camera to wind a 120 roll film up here.
If you don't have any of that camera, that's O.K., for you can do that in the changing bag as we saw earlier.
Maybe you will waste a film until you get used to this.
For this reason, we advise you to practice these procedures in a light place first.
The word for last, after you have a film developed at some shop, do not forget to recieve the spool of a 620 roll film back!
