What date is used when importing images?

[piotergmoter]

Hi

When I import images with this rule:

[date:yyyy-MM-dd_hh.mm.ss]{lower}{unique}.[ext]{lower}

exactly what date is used to make the new name of the image?

The problem was not visible during import from the device which made the photo (camera, phone) but appeared when I was importing using CTRL-ALT-I. So I first copied images using dolphin from mobile phone to my hdd, than imported such images to NAS using digikam. What I have found was that the name of the file had wrong date ie: not the date from the EXIF but the modification date of the file. Is it normal? From my point of view not. The file itself can have bad date, and I'd like to be sure that digikam uses the reliable source of date which means EXIF. So how does  it actually work?

Regards

I have the same issue when I try to import from mobile phone mounted as MTP device. Since many versions ago.

Enable the option in the camera setup: "Use file metadata (makes connection
slower)". The date is now used from EXIF.

Hm, is this feature in the mobile phone? Have not ever seen this.

And this apply only to MTP protocol I guess?

Not in the mobile phone, in the digiKam camera setup page.

Hi,

I know this was already discussed some time ago, but I would still like
to bring it up again:
Someone who actually cares about the picture date (i.e. renames files
accordingly) certainly is interested in the date when the picture was
taken, not some random system date, which is usually not even consistent
on different systems. Taking the time from exif should be the standard
or there should be a much more prominent switch (i.e. directly in the
import ui). As the emails below show you (understandably) cannot expect
a (new) user to look for and find this option.

Cheers,
Simon

I saw this too late, sorry for the double email:
No, this is a digikam setting: Go to "Configure digiKam", "Cameras" and
then to the register "Behavior". There you have to tick the option "Use
file metadata (...)".

Cheers,
Simon

agree with you

I got a strange behavior (I'm new comer on DK) , where when adding some
comment on a set of pictures through "caption" manu on the left and
click on apply to all version (by error, as I was thinking of version of
a picture) , I found that the creation date has been modified by the
date of the modification

all was relatives to pictures made with a smartphone (is it linked?)  
and hopefully the name of the file contain


but just check agoin, changing the date in the caption directly impact
the original date, is it normal ?


regards

frederic
