You can see the correction in the Canvas.
Note: When using the auto-balance control, it’s important to recognize that the color
temperature of the light illuminating the white area you select will affect the hue of the
compensation that is made. If the picture is lit with a combination of daylight and
tungsten sources, selecting a part of the picture illuminated by daylight will result in
compensating the overall color temperature of the image by adding more reds, while
selecting a part of the picture illuminated by tungsten will compensate by adding
more blues. In such a case, you need to simply pick the best possible compromise that
looks right to you.
Next, you’ll focus on the blacks in your image, making further adjustments for more
accurate colors.
