[RT] Issue with "Auto matched curve" with this shot

How much would you have to underexpose there?

Dont’t know, the image is from 2015. Cant remember the scene…

My picture examples are misleading, because the sky is strongly overexposed. Sorry.
Wouldn’t it be better if I deleted my contribution?

Hmm… That’s a fun challenge. Since automatching relies on the JPEG (which likely has camera vignetting/distortion correction applied), then the input to the algorithm should probably be after lens vignetting/distortion correction is applied to the raw file?

Is automatching not done after lens corrections have been applied? Lensfun does not have vignetting correction for my camera. If I manually correct vignetting then hit the Auto-matched tone curve button it makes no difference, the result is still light and faded.
