❚❚ 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 (0 151; to fine-tune white 
balance when L is selected, use the shooting menu as 
described on page 151). 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), stopping 
when the desired value is displayed in the control panel. Rotate 
the dial left to increase the amount of amber (A), right to 
increase the amount of blue (B). At settings other than 0, an 
asterisk (“U”) appears in the control panel.
