Lots of replies with no evidence.....
Maybe the camera was defective? (or user error)... or maybe he's right?
H=If the OP is right that implies some kind of giant global conspiracy where millions of Nikon users all lie on a daily basis and millions of canon//Sony/Fuju/* users who view Nikon files are all part of some great conspiracy.
Or we can conclude the OP is wrong, either making a user error or lieing because he is a troll.
Make a bet, but I would suggest the latter is more likely. Unless I'm color blind then the files my Nikon have produced are spot on, i barely do any PPing.
The OP probably had some kind of custom Wb set on his Nikon or had made adjustments to the lightroom import settings he didn't understand.
