Marcel,

After your latest commits, nef raw files with profiles work, thanks!

I'll have to check again the files stored in-camera as AdobeRGB. Especially
with D40 it is possible that the camera does its processing a little bit
differently for files stored in AdobeRGB. In addition to AdobeRGB, D40 actually
has two sRGB settings with a little colour reproduction. One sRGB setting
should produce more pleasing skin tones, the other enhances colours in nature,
if I remember properly.

However, in D300 Nikon started using Picture Controls which define colour and
tonal settings, and sRGB/AdobeRGB setting was separated from them. That's why 
sRGB and AdobeRGB versions should match closely with D300.

With the files converted to AdobeRGB with Capture NX2, it's possible that there
are some minor differences compared to the original sRGB nef, since Capture NX2
might use a little bit different (better) raw-decoding algorithm than the
camera.


I'll have time to test this better tomorrow, but so far things look good! :-)
