Hi, I want to create a basecurve that will match another image. I took dpreview's image of a Kodak grayscale (20 patches), and developed it into tiff in Capture 1. Now I can open both the tiff and RAW files in darktable and see the difference in L value for each patch (using the color picker). The raw file is loaded with a flat curve, which I want to modify to the L values for each patch will match. As I see it there are two options:
1. Manually tweak the basecurve until I reach a satisfactory result - very manual and probably would take a lot of time, and not robust. 2. Create a curve using the L value of the raw and tiff as nodes How can I create a new curve out of a series of node coordinates? I've tried to look at how the curves are saved in exported styles, and I see a base64 encoded string but I'm having a hard time guessing what the actual curve representation is. So, before I try to delve into the code it would be great if someone can point me to the format used to represent basecurves.
