❚❚The UButton

At settings other than K(Choose color temp.) and L(Preset manual), the Ubutton can be used to fine-tune white balance on the amber (A)–blue (B) axis (0 149; to fine-tune white balance when Lis 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.
