Color Grading plug-in, creates a cine image look based on user input. For a contemporary image look, use complimentary colors in shadows and highlights. It is also preferable to be used on a somewhat neutral image (ie pre white balanced) for best control of the final result. If it's not a raw image balance it before with Color Balance 2.

Version 1.9.1 of Color Grading plug-in depends on a custom GEGL plugin written in C. In Windows the .dll binary is provided, in Linux .so file must be built by the user. The need for this new dependecy came up due to GIMP changing how pdb levels work, used to work on non linear light now work on linear light. Causing the same input to deliver completely different output.
