darktable gets color managed light table mode

The darktable team released an update of this digital photography application. The main new improvement is basic color management in the light table mode.

Ideally stable releases shouldn't be getting any major new features, and technically this is a quick fix indeed, but it (arguably) changes a lot.

Before the newly released version darktable didn't have any color management in the light table mode (where reviewing of photo sessions happens). Now color management is off only when embedded JPEG images from RAW are used for the thumbnails.

So, if you want the application to color-manage previews in this mode, you can enforce rendering of initial previews with darktable. Go to the Preferences dialog and enable this checkbox:

The preview toggle

This will make darktable render JPEG thumbnails whenever you import new RAW files to your library. Needless to say, whenever you edit an image, the app regenerates its preview which becomes color-managed anyway.

On top of that, advanced color matrices were improved for Nikon D800 and Canon 5D Mark III. The latter also got white balance presets. Likewise, WB presets were updated for several more cameras.

You can read the full list of changes in the official announcement. Source code is available for downloading, and Pascal's PPA already has the update.

  1. Stupid question perhaps, but what does a camera-specific colour matrix do? I know that e.g. ColorHug needs colour matrixes that correspond to the monitor type, since there’s some conversion between its own RGB reader, and the light sent by the monitor (if I understand correctly), but where does it apply in darktable?

    (also, is there any possibility you could make the tab button on these comments move first to the antispam box and _then_ to submit?)

    I’ll see what I can do about Tab :)
