### 7.7.27 Digital Camera/White Point

White Point allows to correct the white point of an image. This way the brightness and colors are corrected, too.

There are two different modes:

- Setup White Point
In this case the color field defines the white point which can be read from the image by using the mouse, too. If there is no white in an image, Limit can be used to set the relative brightness of white to the given color.
Automatic checks the image and calculates a white point and a limit from its content. Please note, that the automatic mode may calculate a wrong result on images with an extreme content, i.e. one color is absolutely dominating.
- Setup Gray Point
If an image doesn‘t contain white, a gray point can be set, too. The white point will be extrapolated based on this gray point. Fix White Point keeps the white and black in an image unchanged. In between the colors are modified accordingly to the gray point.

Gamma changes the brightness of the image.
