Darktable 4.0 Released with New Features! How to Install via Ubuntu PPA

Darktable, free open-source photography app and raw developer, now is at the new major 4.0 release! See what’s new and how to install it in Ubuntu 22.04, Ubuntu 20.04 & Ubuntu 18.04.

Darktable 4.0 features Filmic v6 which introduced new color science. The change removes the mandatory desaturation close to medium white and black and replaces it with a true gamut mapping against the output (or export) color space. For those still prefer the “desaturated highlights” look, you can still do this by disabling chroma preservation.

The release also include a new feature in the “exposure” and “color calibration” modules, allows to define and save a target color/exposure for the color pickers, in order to match any source object in the image against an arbitrary target color.

Other changes include:

  • New “guided laplacian” method in “highlight reconstruction” module.
  • Uniform Color Space 2022 (UCS 22) specifically for the purpose of artistic saturation changes
  • Completely UI revamp to improve look and consistency.
  • Change default theme to Elegant Grey.
  • New “collection filters” module
  • Support for EXR 16-bit (half) float export
  • Many other changes, bug-fixes, and new camera support.
  • See the release note for details.
