date problem

[Andreas T. Ege]

Hi there,

when I edit images with gimp, the original metadata gets lost, so I
usually save the metadata from the corresponding raw image, and import
them back to the edited image. This works fine for most data, but not
for the creation time of the image, that stays the time I edited the
image. In the saved exif data the creation time is correct, but it
doesn't appear to be imported together with the rest of the data. And I
can't find a way to change this within digikam.
Is there an easy way to do this from inside digikam automatically, or do
I really have to adjust the creation time stamp by hand?

Try ReRead metadata from image to database. There is this option in Image menu.

In 3.4.0, this option can be processed in batch with maintenance tool.
It can use multicore CPU.

Note : it's serious problem with gimp to lost metadata. I know this
problem since many year ago.

With all 3rd party components available in open-source to manage
metadata, it's to gimp team to fix seriously this problem. After all,
Photoshop take a care about metadata. why not Gimp ?

I'd probably write a small shell script which backs up the exif data (through exiftools, exiv or what not), invoke Gimp and restore the exif data thereafter. That should also take care of the correct creation date. Then invoke this script from within Digikam as an "edit with the gimp".

I'm surprised though that Gimp manages the metadata so badly. Shouldn't this rather be fixed in the Gimp?
