How to Install Darktable 2.2 in Ubuntu 16.04, Linux Mint 18

Darktable 2.2

The Darktable RAW photo workflow software has reached the new 2.2 stable series. Here’s how to install or upgrade it in Ubuntu 16.04, Ubuntu 16.10, and/or Linux Mint 18.

What’s new in Darktable 2.2:

  • Add new automatic perspective correction module
  • Liquify tool for all your fancy pixel moving
  • A new image module to use a Color Look Up Table (CLUT) to change colors in the image
  • In Highlight reconstruction module, the mode LCh reconstruction was completely rewritten, and is no longer useless
  • A new tool, darktable-chart, that goes along with the CLUT module, to create styles for the latter
  • Exposure fusion in the basecurve module to lower the dynamic range of images
  • Add new raw overexposure indication
  • Darkroom: the preview (in top-left corner) is now no longer pre-demosaiced (but just downscaled without demosaicing it at the same time), thus the preview, color picker, histogram show the proper results, especially when there is highlight clipping.
  • See the release note for more.
