White Balance

Corrects all colors using the reference point in the image.

If, for example, you shoot a video under poor lighting conditions and it turns out a bit reddish, you can automatically correct the colors to normal values. All that is required is to record a white rectangle somewhere (you can record a piece of white paper while shooting the video) under the same conditions. Then in the preview window of this function click on the white area that you recorded (even though it may look reddish now).

White Balance will then calculate how different is the recorded white area from the pure white color, compute the necessary correction factor and adjust all the colors in the video using this value. After the White Balance does its job, the area you selected should become white, and all other colors in the video should look more natural.
