1582 -1623 - PDF, DNG - DateTime Original - Read Tags from file

[Uwe]

Hello,

the action "Read Tags from file" doesn't read the existing XMP-exif:DateTimeOriginal but XMP-xmp:CreateDate of a PDF file. This tag should never be read because it's not in the Daminion mapping list below:

 

 

EXIF:DateTimeOriginal,

XMP:EXIF:DateTimeOriginal,

IPTC:DateTimeCreated,

XMP:Photoshop:DateCreated,

Video:CreateDate,

File:CreationTime

Update:

the same happens with DNG files taken by the camera "Leica V-Lux 3". Even if the tag Exif:DateTimeOriginal exists, the action reads Exif:CreateDate.

BUT not with DNG taken by a Canon G16. Very strange!

Hello,

it seems to be a little bit more complex regarding the DNG files taken by a Leica V-Lux 3. The files were converted by the Adobe DNG converter from the original RAW file some years ago.

The current status is: there are duplicate Exif tags in the DNG file.

In the post above I supposed the Exif:CreateDate was used to read the tags (in the Import action) but this is wrong.

1. Daminion reads the tag Exif:DateTimeOriginal BUT the tag of the second part in the Import process. In this case: "2014:07:29 17:59:19"

2. The Daminion action "Show all metadata" doesn't show both parts and I get wrong/different information about the "DateTime Original" tag.

3. The action "Batch Rename preset:%date_%time.%ext" renames the file to "20140729_175919.dng".

4. Changing now DateTime Creation in the Properties Panel to "2014:07:29 17:59:17" overwrites "Exif:DateTimeOriginal" of the first part with the same data. Using the ExifTool command line to change the DateTimeOriginal the first part is changed.

5. And now: the same action "Batch Rename preset:%date_%time.%ext" renames the file to "20140729_175917.dng".

That means: the rename function doesn't use the "Exif:DateTimeOriginal" metadata of the file but the metadata of the item in the catalog. And they were changed in step 4 from "2014:07:29 17:59:19" to "2014:07:29 17:59:17".

The problems are: the handling of the duplicate tags in the Import process and the "Read Tags from file" action which use the second part of the duplicated Exif metadata.

Hello,

any news regarding this topic - it's still an issue in build 1623? Here is the link to the answer of Phil Harvey (author of the ExifTool):

http://u88.n24.queensu.ca/exiftool/forum/index.php/topic,8118.msg41576.html#msg41576

This is the output of the -v option of the ExifTool:

Metadata_DNG_Leica.txt

Hello,

I have a temporary workaround for single files using the Exiftool GUI but not to handle 100+ files.

1. Export the original DNG file to a new folder and select it in the ExifToolGUI

2. ExifToolGUI->menu->Export/Import->Extract preview image from selected-> DNG file

3. ExifToolGUI->menu->Export/Import->Copy metadata into JPG or TIF files...

4. ExifToolGUI->menu->Modify->remove metadata...

5. ExifToolGUI->menu->Export/Import->Copy metadata from single file...

6. Copy back the DNG file to the original folder, then: Daminion "Read tags from file"

Now, there isn't a duplicated section in the DNG file and Daminin can handle the DNG file as expected.
