Use DNG 15.2 to convert Panasonic Lumix DC-S3M2 to DNG with Lossy Compression enabled. 
Attempt to import into CR 15.2 or LrC 12.2
File is not readable



Bug in LRC 12.2 und Camera Raw 15.2 bei der DNG-Konvertierung von Lumix DC-S5M2 Raw Dateien (*.RW2). Nach Konvertierung der RAW Dateien in das DNG-Format zeigt LRC einen Fehler an und die Dateien lassen sich nicht weiterverarbeiten. Auch PS und Bridge sind betroffen.

After converting the RAW files to DNG format

Is that conversion via LrC, or from a third party RAW converter?

Ja, die Konvertierung erfolgte über LRC und auch über Adobe DNG Konverter!

das Problem tritt nur auf, wenn die Option "lossles compression " gewählt wurde!

I've just checked Camera Raw 15.2 and Lightroom Classic 12.2 and they can convert to DNG and process the converted DNG file

 

Files converted from Lumix DC-S5M2 Raw (RW2) files using DNG Converter and imported into LrC 12.2 can also be processed without issue.

 

I'm using macOS 13.2.1 Ventura

 

May be you could upload an original and DNG version of the files you're having problems with to Dropbox or similar, then post alink to same when you next reply.

    The issue only happens if the dng conversion is set with the option "lossless compression"!

    Hmm, not sure where you're seeing an option for lossless compression as that that's the default conversion for DNG. Are you sure that you're not confusing 'Lossy Compression' as shown on attached screenshot of DNG Converter.

     

    Edit: Attempting to use 'Lossy Compression' results in 'not supported', but this option is only used when lower quality demosaiced images are acceptable.
