Hello,
I don't know when and how it happens but there are duplicate Exif metadata in the DNG file.
How can I remove the duplicate tags (in this case the second block of the Exif tags) because an other program has problems with this duplicate blocks?
Regards, Uwe

Hi Uwe,

I need to see the output of the -v option to figure out what is going on.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Hi Ewe,

I got the output.  The duplicate information is from the embedded JpgFromRaw image that is stored in the DNG.  I don't know why any other program would have troubles with this -- I would be surprised if any other program could extract this information.
