> I had never even heard of an uncut developed roll of film before
That's how film is developed. Someone at a lab has to cut it.
> who is honestly shooting that much 135 film
How about a film lab? A place where "uncut developed film" is extremely common.
>it's worth 1600 Euros to buy a faster scanner for it
Price is 999 euro.
> pros who still shoot film would use a larger format
Some do, some don't. It depends on the project. I'm a little surprised by your comment looking at your history. You say you're a retired professional photographer and you've never heard of "uncut developed film" before? If you're retired in 2025, you must have been working when all photography was on film. You never developed a roll of film before?
