How to embed an ID in Pixel 3a EXIF data?

Question

My wife and I both use Pixel3a phones so we are not always sure which one took which photo.  Is it possible to embed some information into the exif data on one camera for use later as id. thanks

You can use a tool called exiftool (link) it has a command line interface that allows you to modify image tags and metadata. One particular tag you can use to distinguish between 2 devices could be the copyright tag or the CopyrightNotice tag, here is an example of what you could do:

exiftool -rights="Person 1" image_0.jpg

Or even the author meta tag:

exiftool -XMP-dc:Creator="Person 2" image_0.jpg

Here is a list of most if not all EXIF tags among other tags that you can set using exiftool
