### **Chromatic Aberration**

> Macro (anchor)
### **Example: Chromatic Aberration Strength**
Depending on the **Strength** of the chromatic aberration, you can create different looks in your scene. You can imitate the effect of a real camera with subtle aberration, or, if you wish to achieve an artistic effect, consider increasing the Strength parameter, as in the example.

## **File Names of Saved Channels**
---
As expected, channels keep their names as displayed in the VFB when saving them to a single *.vrimg* or *.exr* file (using the **V-Ray raw image file** option from the Frame buffer rollout or the **Save all image channels to single file** VFB button). The same channel names are appended to the files when you use the VFB button **Save all image channels to separate files**.
However, using the **Save separate render channels** option from the Frame buffer rollout to save all layers as separate files saves the **effectsResult** channel to a file with the text *RGB_color* appended to its name, and the RGB channel as *origRGB* instead.
