Regarding the exact color space transformations used by Darktable when processing / saving the sample images I don't know (yet) whether this results from the estimation procedure or some issues / limited understanding When applying the resulting LUT to the RAWs with those test images, there will still be some artifacts near the gamut That may provide a good starting sample set, but additional real-world images are always 5 RAW+JPEG pairs can be photographed at differentĮxposures. (an OLED smartphone with vidid color settings is fine), approx. If the pattern is displayed on a wide-gamut screen May be used to generate a simple test pattern. Lens correction can be deactivated during estimation with the according flag.ĭarktable_lut_generate_pattern The lens correction module should hence be activated when using the LUT. Also, the filmic rgb module should be turned off.Īlso, the lens correction module is activated by default, which can make a huge impact depending on camera/lens Image without the exposure bias correction. The LUTs produced by this module are constructed to resemble the OOC jpeg when used on a raw In default configuration, Darktable may apply an exposure module with camera exposure bias correction automatically Hence, it is advisable to also shoot the in-camera jpegs in Adobe RGB in order to cover the whole available gamut. The resulting LUT is intended for application in Adobe RGB color space. The images should represent a wide variety of colors ideally, the whole Adobe RGB color space is covered.
