Hi Hi, I was googling this some but haven't had much luck. Is there a way to change the Tag or Comment property of a file/image using Python? I read something that said I could use Pillow and Piexif, but im not familiar with piexif.

Any advice is much appreciated

you presumably want to modify the exif data
so you'd want to roundtrip the images by reading them, setting the metadata, and then creating them. e.g. https://stackoverflow.com/questions/44636152/how-to-modify-exif-data-in-python

so im essentially recreating the photos then? Some of them have timestamps from many years ago, I hate to lose that but
hazy rose
timestamps, as in the file itself was created on your machine several years ago?
if the metadata inside them is the timestamp you're talking about, you can just leave that intact
true falcon
Well, I copied the files from an old pc, but they retained their creation date
hazy rose
i wouldn't be attached to the creation date of a file, but if you wanted to you could just not modify the original file
and create a completely new one
or you could modify the metadata of the file itself

_or_ you could modify the metadata of the file itself
That's ideally what I'm wanting, I have about 500gb of photos, and I'm trying to add a tag to each photo as a sort of identifier to mark who the photo is of. After that I'm importing this info into a database table for a future project I'm working on
hazy rose
oh, why not just add the metadata as part of the importing step?
like instead of modifying the file, just doing it when you insert into the db

How might that work?
hazy rose
well, how are you inserting this info into a database?
just modify that flow to be the stage at which you identify who's in a photo
then in the database store that metadata separately
e.g. in a person_to_image join table
true falcon
well, how are you inserting this info into a database?
Haven't nailed it down yet, but once I finish organizing the photos, I'll run a script thst gets the file name, location, full location with file name, file type etc
hazy rose
instead of storing that information in the exif metadata
true falcon
Well my only issue with that is, during the import step I'm not sure how to determine what tag to set for each photo unless I base it off the folder name, but then some folder names are related to trips, some photos may have multiple people
true falcon
then in the database store that metadata separately
So one table for my photo info, another for the metadata?
hazy rose
that's just how i'd represent the many-to-one relationship of people inside a photo
hazy rose
Well my only issue with that is, during the import step I'm not sure how to dete...
at the very least, it sounds like storing this in the exif metadata is not necessary. you could just create a file that lives next to the image that is like a json manifest file containing metadata about the image
hazy rose

but only if you intend to query based on that information. you could also use e.g. a jsonb column in postgres

I'll look into that, I've actually never heard of that tor used it before
