Error: Will not write DNG-file to Lightroom

Raw files from Lumix G9 mk2.

1 Like

Same issue here: the RAWs from my Lumix G9 Mark II open just fine – when trying to save them back to Lightroom Classic, Photo AI reports a “DNG write error”.
The same happens when I open the RAW directly without Lightroom.

There is no processed image. Every file I try from my Lumix G9 Mk II will not write to a DNG file. Files from my Sony a7IV and my LUMIX S5 II works fine.

Here you can download the test file I used and got the result under:

The Lumix G9 MK II is not currently supported camera profile with Topaz Photo AI.

We utilize a third-party software known as LibRAW for RAW file processing. We will need to patiently await an update from them regarding their RAW library before we can incorporate it into our software.

During this period, it would be necessary for you to convert those RW2 files into either TIFF or JPG format.
