I made the test again, and I think this method doesn't work.
- I use a jpg with " Image Description               : SAMSUNG CSC"
- I rename it to test.jpg and add it to a digikam album
- under image/metadata/modify/exif, I see that description and caption were set
to "SAMSUNG CSC" as expected when image is imported
- while digikam runs, I removed the tags using exiftool :
exiftool -ImageDescription= -UserComment= -Description=  -Caption-Abstract=
-Comment= test.jpg
- the change is detected in digikam, if I use image/metadata/modify, there's no
more trace of the "SAMSUNG CSC" text in any field of exif/iptc/xmp, so the
change is correct. The tag was correctly removed from all data (doing 'strings
test.jpg |grep "SAMSUNG CSC"' finds nothing)
- I click on "more" in the "captions and tags" sidebar window, choose "read
metadata from file", but nothing happens, the text is still "SAMSUNG CSC" in
the caption window.


> So, the first method is the most simple to apply.
I confirmed this one worked on all my photos.
