Hello,

Digikam uses only a subset of all image metadata, and reads that when
scanning new images.
When you modifie metadata from « outside », jhead, exiftool et al.,
Digikam can't guess data has changed.

If you start the metadata editor, all is reload before edition and that's
why you see correct values in properties tabs.

But if you just want to make Digikam aware of some modifications you've
done, select your image(s) then run « Reread metadata from image ».
It's not automatic when you modify your files by your own.
