If I remember right, osx has native support for reading only NTFS disks, and it's not the other way around (windows doesn't support hfs+ or apfs, not even reading). I'm in a similar situation, I have multiple copies on different formats, but the main data is on a ntfs

So out of touch. A mom of 3 using icloud, and you blab about rclone, amazon glacier and whatever.

Sometimes I feel everybody repeat over and over their nerdy lesson without reading the post, I feel this sub is often useless...

I use Adobe Lightroom Classic for all my pictures. There's an auto improve command that I always use to start edit my pics, you could use something like that, but I'm not sure how it behave with colors (with normal digital pictures it usually set exposition, litghs and shades). You can install the trial version and be able to edit and export all the picture you want!
