The FAW function adjusts the white balance value automatically as the lighting condition changes.

This mode is convenient when you have no time to adjust the white balance or when the camera is moved frequently in and out of places under different lighting conditions.

Setting procedure

The FAW function can be activated with item "FAW" on the OPERATION Menu.

This item allows allocation of the FAW function to the A, B or PRST position of the WHT.BAL selector switch.

☞See "OPERATION Screen" on page 73.

CAUTION:

The FAW (Full-time Auto White balance) function cannot provide optimum white balance with a subject outside the FAW adjustment range, for example when it contains only a single color or not enough white color.
