Nikon D3400 - Fine-Tuning White Balance

124 P, S, A, and M Modes
Fine-Tuning White Balance
White balance can be “fine-tuned” to compensate for variations
in the color of the light source or to introduce a deliberate color
cast into an image. White balance is fine-tuned using the White
balance option in the shooting menu.
1 Display fine-tuning options.
Highlight a white balance option
and press 2 (if Fluorescent is
selected, highlight the desired
lighting type and press 2; note that
fine-tuning is not available with
Preset manual).
2 Fine-tune white balance.
Use the multi selector to fine-tune
white balance. White balance can be
fine-tuned on the amber (A)–blue (B)
axis in steps of 0.5 and the green (G)–
magenta (M) axis in steps of 0.25. The
horizontal (amber-blue) axis
corresponds to color temperature,
while the vertical (green-magenta)
axis has effects similar to those
achieved with the corresponding color compensation (CC)
filters. The horizontal axis is ruled in increments equivalent to
about 5 mired, the vertical axis in increments of about 0.05
diffuse density units.
