Hi all,

I have tried very hard to understand color management for years, and I think I have finally understood the basics. I have now calibrated my Dell U2410 with an i1 display pro colorimeter + DispcalGUI, installied the profile system wide, and am now using this profile in darktable. I have even verified the calibration and profile using the colorimeter and everything seems to be ok.

Calibration was done in standard mode of the display, 30 Brightness, 50 contrast, and 6500K black body as whitepoint target.

If I now load a raw image from my Canon EOS 5D II in darktable and disable all processing (except sharpening), I would expect to get a usable/neutral rendition of the photo on my display. However, the photos look very dull/muted. Since darktable comes with an existing input profile for the 5D II (it does, doesn't it?) I would expect the default look to look more or less natural, without having to fiddle with curves, saturation, or contrast in any way. But this does not seem to be true. It looks completely wrong.

You can find an example image here.

*raw* *CR2*: http://cornergraf.net/darktable.org/raw.CR2
*exported JPG* with everything off, except sharpening: http://cornergraf.net/darktable.org/muted2.jpg *exported JPG* with black level +0.10, and exposure +1.3: http://cornergraf.net/darktable.org/proper2.jpg

Please help me understand what is going on here. Is this the way the files should look like straight out of the camera and with no processing? Is my display calibrated or profiled incorrectly? What do you get when you look at the exported JPG files, which one looks more natural?

I would greatly appreciate any help you can give me.

Regards,
Eckhart
