           Summary: DNG Converter damages white balance metadata
           Product: digikam
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: michal at thoma.cz


Version:           0.10 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

When converting PEF image to DNG using digikam DNG Converter the camera white
balance information is lost in the process and 6500 K white balance is
hardcoded to image instead. This severely complicates later editing in the RAW
conversion utlity and also compromises creation of the preview image.

Here could be find sample images (original PEF, Adobe Converted .dng and
Digikam converted .dng)

There are more differences in the exif in Adobe and Digkam DNGs though I only
this proved severe problem so far.

I consider this issue so severe and unrecoverable data lost, that until
resolved I would recommend using of Digikam converter only for experimental
purpose.
