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?

History

Import script

  • Script with generated base curve - the naming for the generated base curved was fixed in this script
  • Script with fixed base curve - I dumped the sqlite3 database and got some working sql statements

dc-g9-fixed-2.sh - Now with auto-apply for Maker: "Panasonic", Model: "DC-G9"

#3 Updated by Daniel Developer about 1 year ago

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