Hello,<br>
<br>
thanks for your reply.<br>
<br>
I did read the docs before questioning but I was still not sure. <br>
Actually my question came from the fact that Digikam is warning
about using Exiftool might corrupt your files, so I was thinking
that enabling it just for RAW & read-only files would make
sense, keeping exiv2 used for all others.<br>
<br>
From you answer I understand that internally Digikam always use
Exiv2 object/structure, but when you enable Exiftool then all data
is read/written through Exiftool.<br>
<br>
I do have backup anyway so if Exiftool corrupts files I can
rollback.<br>
<br>
Thanks for this great tool, and by the way the new Face
detection/recognition in 8.6.0 is impressive compared to old
versions.<br>
<br>
Thanks<br>

<div>Exiftool is only used to write/read metadata from/to files.
Internally the data is still hosted in the Exiv2 containers.
Exiftool is able to handle these containers as well.</div>

</div>
<div>As ExifTool are Perl scripts, it's slower than Exiv2 which
is C++ compiled, but the abstract layer to deal with file
format is so far more advanced than Exiv2.</div>

<div>Playing with RAW and Video files for example with Exiv2 is
poor quality, where ExifTool rocks. This is why this kind of
option exists in digiKam...</div>

<div> Hello,<br>
<br>
using Digikam 8.6.0 I would like to write metadata to raw
files (CR2 in my case), but keep using exiv2 for others as
it is faster an works well.<br>
I'm not sure about the behavior of the settings: "Delegate
to ExifTool backend all operations"<br>
This make me think than exiv2 will not be used at all in
that case, but then if you click "If possible write metadata
to RAW files" the popup indicates that Exiftool will <b>only
</b>be used for RAW files.<br>
<br>
Could you clarify the behavior ?<br>
<br>
Thanks<br>
