       darktable manages your camera raw files and images in a database, lets you
       view them through lighttable mode and develop/enhance them in darkroom mode.

       Other modes besides lighttable and darkroom are a map for geotagging,
       tethering, print and a slideshow.

       of its processing at very high precision.
