I believe there is an exif tag for this. Maybe we can look at adding/using it to implement this feature.

[Chacsam]

That would be a useful feature indeed

[dcrum]

I also think this may be a good feature to add. I suppose i could rotate manually with the stored files with ffmpeg but i dont know if immich would recognize them...

[GingerZero]

I also would find this feature immensely useful.

In my use case it only concerns picture that don't have an orientation tag in the metadata of the file. Some details...:
After having tested Immich with just my Phone's uploads, I was so satisfied that I decided to try and import all my old images since my family's first digital camera.
The older pictures unfortunately did cause some problems. Through the years, the images were stored in many different places and have been added to various programs. As a result, I have multiple issues, chief of which is the image rotation. Some portrait shots aren't rotated properly and a lot of older landscape photos (including digitized photos from the 80s) are inverted, so ground at the top and sky at the bottom of the image. While this would be expected behaviour for Australia, none of my photos are from Australia, so it clearly is a problem as it isn't reflective of reality.

I was thinking to use some ml model for image orientation detection (or maybe creating one), like with google photos in the utility section

There's already been a lot on this topic. For the immediate future the plan is to leave the original alone and write to a sidecar file instead.

I can see the value of not touching the originals at all, so that sounds good to me. Thanks!

[jrasm91]

Yeah and most tools support getting metadata from them as well so it should transfer to whatever tool or software you wanted to move to.

[aisbergde]

Storing in sidecar should be fine, because digiKam (or other software) should be able to detect this. And then these software can optionally write back into the assets, if required.

Does immich only check external libraries for changes, or does it check the default libraries too?

Same question for all changes in General: Is it a good way to change assets in default library outside immich (rotation, geo location, ...) and will immich detect these changes and reimport metadata and recreate thumbnails? Or is immich still on the trip, that no external changes should happen?
