I begin to like darktable, so I upgraded from the Debian-provided version 3.2 to a self-compiled backport of 3.4. I enabled “modern” color processing and had a look at some of my test images. In most cases my impression is that the new colors are an improvement. That is particularly visible in a high-iso shot with rather extreme low K lighting where previously some wood colors were really off.
But in one case I noticed a strange effect of the new pipeline. I post two JPEGs as rendered by darktable 3.4 (with my kid’s faces masked). The first one is darktable’s 3.2 default processing (scene-referred), with no changes whatsoever (other than enabling hotpixel removal and automatic lens corrections). The second one is the same RAW file, but with the new modern color processing applied. The colors of the sofa portion that is seen between the heads of the kids are particularly bizarre
I read the change log of 3.4 and searched the web, but did not find anything useful. Has anyone encountered similar problems? (I would be happy to provide the RAW file if there was some way to mask the faces.)
Thanks in advance for any hints.
