Ultimately I had a look at the latest versions of UFRaw to process the RAW files of my brand new Nikon D90 DSLR, as Bibble does not support those RAW files yet (although, there is a workaround posted in the Bibble forums).

I came across a few interesing links:

• Color profiling your own DSLR http://blog.pcode.nl … -your-own-dslr-redux
• Getting Nikon color profiles, explaining how Nikon software is doing this: http://blog.crushedr … r.com/nikon/raw.html

After reading the second one I booted my windows machine, installed the Nikon ViewNX software I got with the camera (you don’t need CaptureNX) and got a color profile for my “default” camera settings. The Nikon color profiles require gamma 0.45 and linearity 0, as explained above.

I did not discover any legal constraint, so you can get this color profile here, for the case you don’t want to boot any windows machine or you don’t want to install any Nikon software.
