Bug 276418

Version:           2.0.0 (using KDE 4.6.4) 
OS:                Linux

Especially for beginners it would be handy if digikam supplied some presets for the demosaicing tool's luminosity curve.

The curve profiles should not only have the curve data but also a camera manufacturer tag in order for digikam to be able to automatically pick the correct preset depending on the camera the picture was taken with. For further infos relating the idea behind that feature see bug 276417.

Maybe this report can act as collection for those presets.

My first try for a luminosity curve that fits Nikon cameras:

NOTE: This curve works with highlighting set to anything but "solid white".
To try it you have to quit digikam and edit your ~/.kde4/share/config/digikamrc in the [RAW Import Settings] section.
