>if the same photo atelier develops and scans. Sounds quite convenient.

And if by any chance I would get more than 4 good photos (in a 120 size roll) that I would want to be scanned with professional scanner, it's cheaper to let them scan the whole film at the same time because afterwards it would be 5€/frame. But of course that's quite optimistic of me, that I could get at least 4 good or excellent photos that are in my mind worthy of a professional scanner. 😁 But as I have payed them to scan the whole film, I must think that every single frame truly is worth my money.

>I read an article about long-term storage of films and it appears that storing them rolled deteriorates the film quality with time

They said the exact same thing when I asked them not to cut the film because I thought it would be easier for me to store it. So it's cut and in negative sleeves which are in paper bags.
