Yes, I use sidecars, I never use IPTC and EXIF. Cameras creates EXIF but I
don't need this kind of metadata.
May be I'm wrong but I think converting IPTC to XMP is useless because Digikam
never ends recreating

--- Comment #24 from Maik Qualmann ---
I'm guessing you're using sidecars. There is an interaction between XMP and
EXIF/IPTC. Check out the XMP conversion table:

To prevent this, you would have to deactivate the

I see the new BQM tool doesn't remove all IPTC metadata
To reproduce:
select tiff image
In BQM choose remove image IPTC metadata "completely"
remove IPTC
In metadata editor
item -> edit metadata -> IPTC -> keyword

--- Comment #22 from maderios ---
Because the problem comes from IPTC, not using IPTC would be a good thing but i
did not find a way to disable it. Is it possible?

Strangely, it keeps metadata now, it works. I don't understand what happened,
sorry for the noise...

I can't reproduce it, I used your sample image for testing, XMP remains. Please
test it again.

Yes, remove IPTC metadata works in BQM but i see XMP tags are no more displayed
in thumbnail after removing IPTC
To reproduce, in BQM:
Metadata
remove metadata
IPTC/preview image is checked
XMP and exif are not checked

The function was just added yesterday, it is Comment 6. In the Metadata Remover
in the IPTC section.

Another fact is that if programs like Gimp or Rawtherapee do not update the
embedded preview image, you think you have removed sensitive information with a
crop, but it is still in the preview image.

I get same issue after rotating image with Gimp 2.10.
Open tiff image in Digikam with Gimp
In Gimp, rotate and save it
New tiff image/rotated/thumbnail is not displayed in Digikam, only original

I understand what you mean, I have to investigate and may be, report issue
upstream.
Thanks for these explanations

Do not you understand? digiKam uses the embedded preview image in the TIFF
image, if it exists, to create thumbnails faster. Rawtherapee removed this
thumbnail in older versions, so digiKam created the thumbnail

Same issue in Digikam with tiff files cropped with Rawtherapee git version.
No issue with two file managers, Dolphin 23.08.4-1 and Pcmanfm-Qt 1.4.0. They
display cropped cropped file/ tiff thumbnails normally.

--- Comment #10 from Maik Qualmann ---
I have Rawtherapee 5.9 here, this version removes the IPTC preview, so the
thumbnail in digiKam is correct. If the Rawtherapee git version keeps the IPTC
preview but does not update it, that is a bug.

If you're concerned about the appearance/size of the cropped image, it's
because there's a preview image included that Rawtherapee hasn't adjusted when
I compare the bytes. Now digiKam uses the preview image for

Both TIFF files are also displayed here under my Linux version. The original is
uncompressed, the cropped is compressed with Adobe Deflate.

TIFF can use special compress algorithm as ZIP. libtiff must be compiled with
this kind of support (optional). If RawTherapee enable an exotic compression
method, this is not portable.
