I would like to update a photo (Photo A) with another (Photo B).
The result should be that Photo A looks like Photo B, but can be reverted back to Photo A. Is there an extension that will let me do this on iOS? I am using the External Editors extension to achieve this on the Mac.
For example, on a Mac I can choose to edit a RAW image from the Photos app with Lightroom and I then end up with two identical images.
I would like to be able to do the same sort of thing in iOS so that I can edit a RAW file and then revert back to it later, but without having to see it in the library.
