Just Realized Something About Adobe DNG Converter

For some reason, I've never actually used DNG converter to make Panasonic's .RW2 files work in Lightroom 6 (my stubborn final non-subscription version). While I owned the GX9, I wasn't able to edit RAWs on the desktop with Lightroom, because I own the old version and was a dummy who didn't remember that you can use DNG converter. It wasn't all bad, because it taught me that Panasonic's JPEG engine has gotten really good, and I learned my way around the RAW conversion features in-camera, which allowed me to create some styles I really like.

However, I just installed DNG converter and put my GX9 folder through, so now I have DNGs (which are my preferred RAW files anyway), and straightway I noticed something: Lightroom's interpretation of the files is the same as Panasonic's. Colors look identical. You know how traditionally Panasonic colors have looked strange (at least in older Lightroom versions) once Adobe has their way with them. Here's an example of a DNG from a GX9 .RW2 file next to the in-camera JPEG:

They are identical, aside from the slight adjustments I made to the JPEG tone curve. This really excites me, because I have enjoyed the Panasonic standard JPEG colors since the GX85, but they lose a lot of their punch when LR gets a hold of them and turns them a little weird. Now, I have a way around that. Lightroom 6 starts from the same point as the camera now.

That was a DNG run through the converter from Panasonic's RW2, compared with the camera JPEG.

As an update, I'm not sure the noise performance is as good once the RW2 is converted to DNG. It's hard to compare with anything other than GX85 16MP files, so I can't tell. Maybe I'll download a trial of current LR and see how they compare. At any rate, I don't have the GX9 anymore, so I have less of a reason to investigate this.

Based on what I have read on the internet, Adobe DNG converter actually applies Adobe profiles to converted RAW files.

When I first started editing then new GX9 RAW files, editors (non-Adobe) I had on my computer rendered everything purple because I had not updated them with GX9 RW2 profile which seems to be different than other models.

I did however discover that Adobe DNG converted already supported GX9 variant of RW2 and files converted to DNG had OK colours. Even though not as good as in-camera jpg ones.

There's a catch still. DNG converter does not understand all proprietary data in original RAW format (corrections, noise reduction or DR improvement applied to RAW in-body) so something might be lost in the process.
