Free GNU General Public License source code and executable for Apple® macOS™, FreeBSD and GNU/Linux® by The darktable Team. darktable is a photography workflow application and raw image developer with a virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them. Features include:

  • Fully non-destructive editing.

  • All darktable core functions operate on 4x32-bit floating point pixel buffers, enabling SSE instructions for speedups. It offers GPU acceleration via OpenCL (runtime detection and enabling) and has built-in ICC profile support: sRGB, Adobe RGB, XYZ and linear RGB.
  • A collect module allows you to execute flexible database queries, search your images by tags, image rating (stars), color labels and many more. Filtering and sorting your collections within the base query or simple tagging by related tags are useful tools in your every-day photo workflow.


  • Import a variety of standard, raw and high dynamic range image formats (e.g. jpg, cr2, hdr, pfm, .. ).

  • darktable has a zero-latency fullscreen, zoomable user interface through multi-level software caches.

  • Tethered shooting.

  • darktable currently comes with 21 translations: Albanian, Catalan, Czech, Danish, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Polish, Portuguese (Brazilian and Portuguese), Russian, Slovak, Slovenian, Spanish, Swedish, Ukrainian.

  • The powerful export system supports Picasa webalbum, flickr upload, disk storage, 1:1 copy, email attachments and can generate a simple html-based web gallery. darktable allows you to export to low dynamic range (JPEG, PNG, TIFF), 16-bit (PPM, TIFF), or linear high dynamic range (PFM, EXR) images.

  • darktable uses both XMP sidecar files as well as its fast database for saving metadata and processing settings. All Exif data is read and written using libexiv2.
