[Digikam-users] Color management with Nikon d40x

[junk at lexoncom.com]

I was able to find out that I should use:
Nikon DBase for NEF v3.0.0.3001

profile,

But, I still dont understand why images are different in preview and after
raw conversion is applied,

in original nikon software (with profiles applied) images look exactly
like in preview in digicam,

anyone?
