Hi, I have a question regarding profiling with an it8 target and darktable-chart.
What I've done so far: - captured it8 reference images - corrected exposure to match patch GS0 - corrected black point to match patch GS23 - corrected white balance to patch GS5 ← LAB_L > 0 && min(LAB_A² + LAB_B²) - exported to PFM (float) with Lab profile Then in darktable-chart: source image tab: image: exported_image.pfm chart: /usr/share/color/argyll/ref/it8.cht reference values tab: mode: cie/it8 file reference it8: ?? This is where I got stuck. The reference should be the file R123456.txt shipped with the target, right? Selecting it doesn't work, darktable-chart doesn't accept it. I only found tutorials using a jpeg as reference. But if I understand correctly, it should be possible to match the supplied reference values. But how? Or do I need to convert the R123456.txt file somehow? Any pointers appreciated. darktable 2.4.4 Marco ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
