White Balance defines the “true white” in a photo. An image that is too “cool” will have a bluish color cast, and an image that is too “warm” will have a yellowish color cast. White Balance adjustments can quickly correct these issues.
Open an image in Single Photo View, then click the edit icon .
Twirl down the arrow next to White Balance.
Adjust the Temp °K and Tint sliders to remove any unnatural color cast.
