Adjusting the Color Tone for the Light Source
You can correct the white balance that is set. This adjustment will have the same effect as using a commercially-available color temperature conversion filter or color compensating filter. Each color can be corrected to one of nine levels.
This function is for advanced users, particularly for those users who understand the use of color temperature conversion and color compensating filters and their effects.

White Balance Correction​

1 Select [WB Shift/Bkt.].  Under the [ 2] tab, select [WB Shift/Bkt.], then press  The WB correction/WB bracketing screen will appear.

2 Set the white balance correction. Press the cross keys to move the  mark to the desired position. B is for blue, A for amber, M for magenta, and G for green. The image’s color balance will be adjusted toward the color in the direction of the move.   On the right of the screen, “Shift” indicates the direction and correction amount, respectively. Pressing the <DISP> button will cancel all the [WB Shift/Bkt.] settings. Press to exit the setting and return to the menu.

• When the white balance is corrected, will be displayed in the viewfinder and on the LCD monitor. 
• One level of the blue/amber correction is equivalent to approx. 5 mireds of a color temperature conversion filter. (Mired: Measuring unit indicating the density of a color temperature conversion filter.)
