Can you give a rough range of compensation for that amount of work?

Does a better example of explaining it in depth than I can.

If they have a patreon where that’s part of the specific deliverable on whatever tier, they have to kind of keep it behind the paywall so they don’t piss off their paying customers by giving shit away for free that they’re paying for. Understandable.

Definitely weird though, seems like a bit of stretch to have that specifically behind a paywall (unless it’s full details/exif data/edit methods full breakdown on everything)
