Maik,

I think the Adobe SDK is not the problem here. The SDk constructs a tiff/EP compatible file with the Raw image data extracted with libraw.

The SDK make a base tiff file with few metadata, no more. The main job to backport information from RAW to DNG is done by Exiv2, and perhaps unsafe tags are backport too much from original file to the target one.

I think ExifTool will be the ultimate solution here...

Thanks for the test file, I can reproduce the problem with the file. After
converting to DNG, Exiv2 has a problem with the Exif metadata and gives an
error message. The cause is not yet clear, it could also be a problem with the
Adobe SDK. I think we'll have to try again to use a more recent version of the
Adobe SDK, but we've had problems with it so far.
