Description Art 2012-06-14 22:10:14 UTC

I like to rename my images with a 'yyMMdd-hhmmss' format.  I notice that, shooting RAW + JPG, the two files (different formats) for the same image have different names (1 or 2 seconds apart).

e.g.  120612-054700.cr2 and 120612-054701.jpg, even though these are the same image.

I think this is because the rename uses the last modified date, not the date created.  This makes it difficult to tell which images go together, especially if there are several similar compositions taken within a short period of time.

Thanks,
Art

Reproducible: Always

Steps to Reproduce:
1.  Choose Import from Card Readers.
2.  Set rename to [yyMMdd-hhmmss]
3.  Select Download All
Actual Results:  
RAW + JPG image pairs are given different names (the seconds field 'ss' is different);
e.g. 120612-054700.cr2 and 120612-054701.jpg

Expected Results:  
RAW + JPG should have same name; e.g. 120612-054700.cr2 and 120612-054700.jpg.

Are you sure that the file creation date is different than the one you see in digiKam?
As far as I can see from the code and my database, the correct file creation date is used.
Have you downloaded the files from your camera and checked with the "normal" tools for detecting the file creation date?

I had uninstalled digikam so have now reinstalled 2.8.0.  The problem persists.  It occurs consistently but not with every pair of raw + jpg images.

I've attached a capture of the file download screen.  The highlighted .cr2 file is named after the date in 'Camera File Properties'.  Note that the creation date listed under 'Photograph Properties' is two seconds earlier.  As shown in the next screenshot, the .jpg version of the same image is named according to the creation date in 'Photograph Properties'.

I've looked at what my other software says about the .cr2 file and there is some variability.
-Adobe Bridge says the Date Created is 06:08:12 02:19:38, Date Modified 06:08:12 02:19:40.
-Windows 7 says Date Created is 06:08:12 02:19:40 and Date Modified is also 06:08:12 02:19:40 (but reports that the .jpg Date Created is 06:08:12 02:19:38 and .jpg Date Modified is 06:08:12 02:19:40).
Breeze Browser, my usual downloading / sorting program, considers both the .cr2 and .jpg as Created on 06:08:12 02:19:38.

From my point of view, it doesn't matter which is used, as long as they are identical for the .cr2 and .jpg versions of the same image.

Please have a look at 307253: Is the offered patch what you actually request?

Comment 8 Miquel Coll 2016-08-29 19:01:00 UTC

Gilles, I'm facing the same problem in Ubuntu 16.04/Digikam 5.1.0.

Steps to reproduce:

1. Image's EXIF date taken: 02/09/2015 13:13
2. Copied the image from the SD card to an external hard disk to made a backup
3. Then copied again from the external hard disk to the laptop's hard disk to import to digikam. The file's dates get changed: date accessed: 22/08/2016 11:23:18, and date modified 21/08/2016 17:10:51. The EXIF date is the same ;-)
4. Import -> Add images...
5. Select the image to import, rename to custom "[date]" (the same behaviour with "[date:ISO]", "[date:yyyyMMdd]", etc.)
6. The filename of the imported image is 20160821T171051.JPG (for NEF files the date is the same)

The strange thing is that if i rename the imported file (F2) using the same format "[date]" I get the correct image name: 20150902T131352.JPG

Regards
Miquel

DigiKam Import defaults uses the file creation date. For a exact date enable in camera setup the option: Use file metadata (makes connection slower).

Comment 10 Miquel Coll 2016-10-08 05:19:26 UTC

Thanks Maik, and sorry for my late reply!

That's true, but it would be helpful to add a hint in the import screen because it's confusing ;-)
