❚❚The U Button
At settings other than K (Choose color temp.) and L (Preset
manual), the U button can be used to fine-tune white balance
on the amber (A)–blue (B) axis ( 0 149; to fine-tune white balance
when L is selected, use the shooting menu as described on
page 148). Six settings in both directions are available; each
increment is equivalent to about 5 mired (
0 150). Press the U
button and rotate the sub-command dial 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”) appears in the control panel.
