Unsurprisingly, 12-bit and 14-bit have different white levels. Additionally, old code assumed that "*-compressed" always have a fixed whitelevels of (2^bitness)-1), i.e. 4095 or 16383. For that reason, many nikon cameras in cameras.xml had completely arbitrary whitelevel specified, which resulted in wrong image => either way too bright (if 12bit wl was specified, and image is from 14bit-uncompressed) or too dark and with purple highlights (if 14bit wl was specified, and image is from 12bit-uncompressed) or with just purple highlights (all other cases, e.g. "*-compressed"). And no one noticed that ^ it was completely and utterly broken. So when i finally did notice that, i had zero options other than just disable all the nikon cameras for which we do not have proper whitelevel information, and then add the support back on per-camera case once someone provides all the necessary samples. This is the script that gives the list of broken (and disabled in git master) nikon cameras: https://github.com/darktable-org/darktable/blob/master/tools/rawspeed-check-nikon-modes.rb If your camera is in that output, one needs to provide samples to redmine (but do check for duplicates first!) > However, since you mention that you're desperate, > you could build from source.
