Effect

Gaussian Blur

Smooth Gaussian blur with adjustable radius for soft focus and diffusion.

Gaussian blur weights neighbouring pixels with a bell-shaped kernel, a mathematical soft focus used everywhere from photography to computer vision. It is the default smooth because it has no ringing and a predictable fall-off.

Radius is the whole story: a little hides noise, a lot dissolves form into atmosphere.
