Ubuntu Unstable Repository and our Release Candidates

Following is a public service announcement from Pascal de Bruijn, the maintainer of the Ubuntu PPAs. As most of you know, my darktable-unstable PPA was serving as a pre-release repository for our stable maintenance tree, as it usually does. Now as master has settled down, and we’re slowly gearing up for a 2.0 release, I’ll do pre-release (release candidate) builds for darktable 2.0 there. On my darktable-unstable PPA I will support Ubuntu Trusty (14.

On Lens Detection and Correction

darktable (and some other projects, like for example ufraw) don’t do any real lens detection or correction by itself. We depend on two libraries which in most cases are provided by the Linux distribution you’re using. Lens Detection Many image files contain metadata about how the image was created. In case of digital camera images, a standard called Exif is used, this standard allows a camera to record many details about how an image was taken.

Display color management in darktable

The general picture on the modern Linux desktop Modern Linux distros featuring either GNOME, Unity or KDE offer fairly easy configuration of color management, this system level configuration mostly pertains to the handling of an ICC display profile. If you have set a display profile via your system configuration tool (The Color applet in System Settings for GNOME or Unity), there are a few things to keep in mind. An ICC display profile consists of two main parts.

What's involved with adding support for new cameras

Update: Some of the information on this page is oudated. See the github wiki page on camera support for up-to-date instructions. Say you’re running darktable, you’ve just bought a brand spanking new camera and it’s not supported yet by darktable. Here is a list of things that need to be done (typically we’d recommend to check this before actually buying anything, often you’ll be able to find sample raw files online):

Fixed: darktable crashing Unity

Some Ubuntu 12.04 (Precise) users who use Ubuntu’s default Unity desktop environment may have noticed that it’s commonplace for Unity to crash when closing darktable. It so happens that darktable is exposing a bug in Unity, which got fixed upstream with a one-liner patch. The above fix will be available in the next major update of Unity (5.14), but in the meanwhile I cherry picked the relevant patch to the current released version of Unity (5.
