Darktable base curve

[Elle (Elle Stone)]

Regarding “messed up colors” I put up a post with some metrics for measuring “how messed up”, evaluating a test image processed using darktable, comparing a sample “base curve” to the new “unbreak profile” and the new “filmic” module:

Messed up colors by the number - darktable's new unbreak and filmic modules

I’m assuming that the colors in a scene-referred interpolated raw file (no “make it pretty” algorithms) are as close to the actual scene colors as most of us can get given that when we take pictures we don’t also measure scene colors using specialized equipment. If the colors in the scene-referred interpolated image file are taken as the “not messed up” colors, then the degree that post-processing produces “messed up colors” can be quantified given suitable metrics. I used two metrics: How …
