Mostly I develop my RAW photos with Capture One, that is before 2007 and more since 2020, even if I have used it again and again in the meantime – where I used Adobe Lighroom as much as possible.
Over the years, I have tried various other RAW converters and besides Iridient, which interacted very well with Nikon and Fuji files, we used to use Lightzone (with its very interesting zone system) and currently DXO Photolab again.
Photolab introduced with version 4 an AI anti-noise feature called “DeepPrime” and some first tests with older mFT HighISO files were very promising.
After a few years I have updated Lightzone under macOS again. But my Lumix S RAW files are not supported, even if I convert them to DNG. So there is only the detour over a 16Bit TIFF-file. But I still find the zone concept of Lightzone very exciting.
