How To Install DarkTable 2.0 (Photo Manipulation Software) On Ubuntu 15.10, Ubuntu 14.04 And Derivative Systems

As you may know, Darktable is a free, open-source, photo workflow application, managing digital negatives in a database and allowing the users to view them through a zoomable light table. Also, the users can develop and enhance raw images. The photos taken directly and unaltered from the camera’s sensor to the memory card are considered raw.

Also, Darktable supports image processing, crop, exposure, spot removal features and provides high quality output.

The latest version available is Darktable 2.0, which brings the below changes:

GUI:

  • darktable has been ported to gtk-3.0
  • the viewport in darkroom mode is now dynamically sized, you specify the border width
  • side panels now default to a width of 350px in dt 2.0 instead of 300px in dt 1.6
  • further hidpi enhancements
  • navigating lighttable with arrow keys and space/enter
  • brush size/hardness/opacity have key accels
  • allow adding tone- and basecurve nodes with ctrl-click
  • the facebook login procedure is a little different now
  • image information now supports gps altitude

features:

  • new print mode
  • reworked screen color management (softproof, gamut check etc.)
  • delete/trash feature
  • pdf export

  • new “mode” parameter in the export panel to fine tune application of styles upon export

core improvements:

  • new thumbnail cache replaces mipmap cache (much improved speed, stability and seamless support for even up to 4K/5K screens)
  • all thumbnails are now properly fully color-managed
  • it is now possible to generate thumbnails for all images in the library using new darktable-generate-cache tool
  • we no longer drop history entries above the selected one when leaving darkroom mode or switching images
  • high quality export now downsamples before watermark and framing to guarantee consistent results
  • optimizations to loading jpeg’s when using libjpeg-turbo with its custom features
  • asynchronous camera and printer detection, prevents deadlocks in some cases
  • noiseprofiles are in external JSON file now
  • aspect ratios for crop&rotate can be added to config file

image operations:

  • color reconstruction module
  • magic lantern-style deflicker was added to the exposure module (extremely useful for timelapses)
  • text watermarks
  • shadows&highlights: add option for white point adjustment
  • more proper Kelvin temperature, fine-tuning preset interpolation in white balance iop
  • monochrome raw demosaicing (for cameras with color filter array physically removed)
    raw black/white point module

packaging:

  • removed dependency on libraw
  • removed dependency on libsquish (solves patent issues as a side effect)
  • unbundled pugixml, osm-gps-map and colord-gtk

generic:

  • 32-bit support is soft-deprecated due to limited virtual address space
  • support for building with gcc earlier than 4.8 is soft-deprecated
  • numerous memory leaks were exterminated
  • overall stability enhancements

scripting:

  • lua scripts can now add UI elements to the lighttable view (buttons, sliders etc…)
  • a new repository for external lua scripts was started
  • it is now possible to edit the collection filters via lua
  • it is now possible to add new cropping guides via lua
  • it is now possible to run background tasks in lua
  • a lua event is generated when the mouse under the cursor changes

Installation instructions:

Darktable is available via some third party PPA, so installing Darktable on Ubuntu is piece of cake. All you need to do is add the PPA to your system, update the local repository index and install the darktable package:

$ sudo add-apt-repository ppa:pmjdebruijn/darktable-release
$ sudo apt-get update
$ sudo apt-get install darktable

Optional, to remove Darktable, do:

$ sudo apt-get remove darktable

The installation instructions should work on Ubuntu 15.10 Wily Werewolf, Ubuntu 15.04 Vivid Vervet, Ubuntu 14.04 Trusty Tahr and derivative systems like Linux Mint 17.x, Elementary OS 0.3 Freya and other Ubuntu 15.04 and Ubuntu 14.04 derivative systems.
