Including a user-friendly roll ID in JPEG metadata

I see tha NLP automatically generates a roll ID:

But, I think this is related to roll analysis?

What I would love to see is an ID that identifies photos from this physical roll (regardless of whatever the roll analysis feature is doing/not doing) that can be included in the metadata for RAW and exported files. That would make it a breeze to instantly see all photos from a roll.

Example use case:

  • you have imported exported JPEGs into the iOS Photos.app, immich, or some other similar system
  • you see a photo you like somewhere
  • you check the metadata, grab the roll ID, and search for it
  • see rest of the photos

This ID needs to be immutable (or mutable with some effort), and somewhat human-friendly (as opposed to a UUID).

It could be constructed from the film roll data, for example KodakGold-$YYYYMMDD-$five-char-short-alphanum-random-string or some such.

This came up because I do import JPEGs into iCloud Photos, which then shows me random photos regularly, and a lot of times I want to see the rest, but it’s a challenge to dig them all up and see them all together.

TBH this could also be just another string field in the NLP metadata that gets included in the description, up to the user to fill out correctly. But would be cool to see some automation!
