Hi,
The problem of a 2-passes denoising method involving 2 differents
algorithms, the later applied where the former failed, could be the
grain structure (the shape of the noise) would be different along the
picture, thus very unpleasing.
I thought maybe we could instead create some sort of

cal target. I had to adjust them
individually, using the absolute target color, which is not what you
want to do on 48 patches.
I wonder if there is any ways to prevent darktable-chart from generating
tone curves and force it to only adjust the LUT ?
Thank you !
