Description

I have a CR2 image that I added a tag to in darktable. I then
proceeded to export that image to jpeg, and hoped to see the
tag in the exif data of the jpeg file. The tag was missing.

Darktable version is from git, with the most recent changeset

History

#1 Updated by oliviertoulouse - over 8 years ago

confirmed.
After checking, it seems that tags export is broken since ~November 2010

#2 Updated by Simon Spannagel almost 8 years ago

Hm,

exiftool IMG_XYZ.jpg

gives me:

Hierarchical Subject : darktable|format|cr2, Places|Mars, Animals|Marsrover.

Should there be more?

Guys, I know this is an old bug I'm responding to, but I didn't find a newer one.
I'm experiencing a similar bug, but with Version 2.2.4+6 (on mac).

If I apply tags to my .RAF file (Fuji Raw) these will not show up in the exported .jpg.
Is this bug still/again open?

Thanks,
Rolf

Please upload a sample JPEG exported from darktable after tagging the RAW somehow. The size of the JPEG doesn't matter, exporting to 1x1 pixels is fine.

Thanks Tobias,
Attached 3 files. A jpg, the .xmp (that's not really needed, is it?) and a screenshot of the Lighttable step with the tag-module at the right side.

The jpg file does contain some exif information (Image description, Artist, Rating, Copyright) but that was not applied by Darktable, but by Lightroom when I imported the file in Lightroom, some years ago.
Today I imported the .RAF file in Darktable and the Tags which I applied in Lightroom where visible in the Tag-module of Darktable.

However, when I process the file and export it to jpg, it does not include the tags, so it seems.
Do I need to include an additional step/checkbox/setting... before I hit the export button?

Thanks,
Rolf

Very strange, your XMP works with one of my images. Could you upload the original JPEG you used that with please? You can also mail it to me if you are not comfortable sharing original files: .

Edit: I just saw that your original is a RAF file. The XMP however says that it was created for a JPEG. Maybe you mixed something up, applying tags to the wrong picture? That would however still not explain the total lack of XMP data. Are there any messages printed when starting dt from a terminal?

Hi Tobias,

Sorry I couldn't respond earlier. I wasn't at home for couple of days.
I just shared a Dropbox folder with you, since the file was too big for gmail to handle.

I shared the following files:

.dng
Originally imported using Lightroom and added tags/metadata using Lightroom (some yeas ago)

.jpg
Used Darktable to import the same .dng as mentioned above. The tags added by lightroom were visible in Darktable. Exported this .jpg using Darktable, based on the .dng. Tags not visible, image description is visible, like Artist, Rating and Copyright info.

.jpg.xmp
The xmp created by Darktable when exporting the .jpg (same output folder as the.jpg)

I also have a linux machine and got the same result (with other image files)
Please let me know if you want more info or run more scenario's.
I'll be happy to provide and be of assistance.

Thanks,
Rolf

Can you try uploading the files elsewhere? I only get some message that Dropbox wants me to sign in or something. Nothing to download there.

#12 Updated by Rolf Aalders almost 3 years ago

I've just shared the files via WeTransfer.
Hopefully you'll be able to download them :)
Thanks

#14 Updated by Tobias Ellinghaus almost 3 years ago

As this is most likely another bug than the old one from this report we should continue in #11618.
