Description

I use darktable to work on RAW files shot with the Panasonic G9. The standard base curve for "Panasonic like" cameras produces images which are way to dark. I generated a base curve based on instructions found here: https://www.darktable.org/2013/10/about-basecurves/ and https://github.com/darktable-org/darktable/tree/master/tools/basecurve.

Unfortunately the curve looks a bit strange. That's why I fixed it manually within darktable itself. Is there a chance to get this fixed base curve added to darktable?

Original Base Curve files
  • dc-g9.sh (script generated by darktable helpers)
  • basecurve.pdf
  • tonecurve.pdf
Fixed base curve file
  • file.tmp (imported via sqlite3 ~/.config/darktable/data.db '.mode csv' '.import file.dmp presets')

Ok. This version also contains a fix for the tone curve. It was made by visually comparing JPEG and RAW files.
