### 7.7.31 Digital Camera/Chromatic Aberration

Chromatic aberration is an error caused by different refraction of different wavelengths of light. This way in digital images edges may become colored. This error is usually not visible in the center of an image but gets worse towards the edges.

The filter Chromatic Aberration is used to reduce this error or to remove it at all. This is done by moving the red and the blue channel relatively to the green channel. Normally the red channel has to be moved by a negative amount and the blue channel by a positive. The real value depends on the used lens and therefore on the used camera.

Width Compensation ensures, that the displacement at all edges is the same regardless of the distance to the center.
