❚❚ The L (U) Button
At settings other than K (Choose color temp.) and L (Preset
manual), the L (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 menus as
described on page 164). Press the L (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 and information
display. 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).
