Filter parameters


Distance defines the spread of the blur effect. A smaller value means less amount of blur.

Lens Size

Radius of the lens that causes the radial blur. A lower value means the blur amount increases faster with the distance from the center.

Window Size

The amount of the lens that is perfectly flat in the center and thus does not blur.

Chromatic Aberration

Simulates the effect of an imperfect lens that causes colors of different wavelengths to disperse.
