On the other hand, if total annual conventional film sales is only 30 million rolls, then that's pretty depressing. That's not even 3 million film photographers worldwide, I'd say. Probably half that.
Probably the number of 1 to 1.5 million regular standard (non instant) film users globally is realistic.
But I am optimistic that this number can increase significantly in the coming years.
Look at the boom in instant photography, or the very strong revival with vinyl records. Even Sony - the first who switched from vinyl to CD in the 80ies - is now building up a new factory for vinyl records!
