Hello,
I'vr found several Photos with false data.

Now I got one photo changing by choosing menue picture/all metadata/changinging metadata. There I corrected the date of generation.
Now it is correct!
Then I wanted do this for the rest of the twenty pictures. But it doesn't work. There was always only the first of the selected pictures changed.

Thanks

Are you doing this through Dolphin, or another application such as Gwenview / Digikam?
