The Blur > Gaussian Blur effect

An image with a Gaussian Blur may be compared to an image seen through a camera that is not set correctly.
The Gaussian Blur is more precise than the Cubic Blur.

The Blur > Center Blur effect

We studied the Center Blur in detail in lesson 12 about the FX stack concept. The parameters are the position of the center, the power of the blur and the radius of the circle.
