This method allows you to adjust the white balance of an image.

Parameter

Description

Automatic

Activated: The white spot is calculated automatically from the image data.

White Spot

Only visible if the Automatic checkbox is deactivated.

Define the white spot by clicking on the Pick.. button. The mouse pointer then changes to a pipette symbol. Use it to click on a white region of your input image. The coordinates and color values of the selected white spot are displayed next to the button.

Temperature Delta

Specifies the hue by which the pixels are changed. Changing the value by 1 corresponds to a color temperature change of 10 Kelvin.

  • Negative values reduce the color temperature, resulting in a warmer redder hue.
  • Positive values increase the color temperature, resulting in a colder bluer hue.

You can increase or decrease the color temperature by up to 3,000 Kelvin.
