I’m really fond of using the G’MIC Color Presets (particularly the Films: Negative [Old] presets) as a last step (using lut 3D module) in the pipeline before the “output color profile” module in darktable.
I believe the correct way to apply these is to use sRGB as the “application color space” in lut 3D.
I suspect this means my colors will be limited to the rather narrow sRGB color space, even if I chose Adobe RGB as my “export profile” in the “output color profile” module. I’d rather be using a wider gamut. My production master files (TIFF) are in Adobe RGB (1998) since nearly two decades back, so that I’d like to continue with that practice. Can anybody recommend a way of creating wider gamut (Adobe RGB) versions of the presets found at gmic.eu/color_presets/.
Also, would I be better off using HaldCLUT or Cube version of the G’MIC Color Presets for maximum quality? darktable supports both.
I suspect I should ping @patdavid for this question.
