ATTENTION! all steps in this tutorial are done IN THE TOTAL DARKNESS. Once you start you cannot turn on the lights / pull your hands out of the dark bag. A MICRO SECOND OF LIGHT WILL DESTROY YOUR FILM
What'll I do with the 120 spool. Well!! If you send your films away to develop.. Before you do.. Re-spool back on to the 120 and re-use your precious 620 again keeping it safe from loss.
Clinching... Well when you are spooling and you pull to tighten the film in the thinner spool, you are clinching. This creates scratches on your film and will show up in your photos. Avoid doing this.
