white balance and multiple exposure

Normally, when one shoots raw white balance is not applied to raw data. With Nikon, we have 2 exceptions:

- older sRAW format, pre-D850, had, among other things, white balance applied

- multiple exposure NEFs also have white balance applied; if you are interested in what were the white balance coefficients, do not look into the usual place, you will find all 1s there; look at the tag 0x003b:

$ exiftool -H -S -G -U -Nikon_0x003b /Users/iliah/Nikon\ Df\ multishot/_DSC2636.NEF
[MakerNotes] 0x003b Nikon_0x003b: 1.97265625 1.59375 1 1

$

The order of multipliers is Red, Blue, Green1, Green2
