I would like to undo (as fas as possible) the WB preconditioning of my Nikon D600 raw files.
However, I do not know where to find the red and blue scale factors used for digital mutiplication (I am using Libraw to read the files).
Would you know where to find, or how to derive, these values?
And what about black compensation?
Are the NEF raw values black corrected? And if so, by which black value(s)?
I appreciate any help on the subjects!
