Utilities

darktable-cli

Using darktable-cli it is possible to use darktable for a non-interactive batch processing and export.

darktable-cmstest

darktable-cmstest helps debugging color management issues (eg. exported photo colors don't match the darktable's). Also it indicates whether the colord USE flag was enabled.

darktable-cltest

Darktable with enabled opencl USE flag supports OpenCL-based GPU acceleration. The darktable-cltest utility helps debugging the darktable's setup and OpenCL driver interactions.

dt-curve-tool

In order to improve approximation of camera's built-in JPEG engine with the default RAW processing settings you can use the dt-curve-tool.
