❚❚ The U Button
At settings other than K (Choose color temp.) and L (Preset

balance when L is selected, use the photo shooting menu as
described on page 179). Press the U button and rotate the
sub-command dial to fine-tune white balance in steps of 0.5
(with each full increment equivalent to about 5 mired) until the
desired value is displayed in the control panel. Rotating the sub-
command dial to the left increases the amount of amber (A).
Rotating the sub-command dial to the right increases the
amount of blue (B). At settings other than 0, an asterisk ("U")
