Adjusting the ND offset values
If an ND filter is attached to the matte box, etc., the white
balance may be in variance. In such a case, adjust the ND
offset so that you can retrieve the white balance
compensation value using the ND filter selection page on
the subdisplay.
The offset values ND: 2 to 5 are stored with respect to the
white balance stored for ND: 1 as the reference.
