description: There are many different effects that go under the name of "diffusion", seemingly all of the inspired by the effect you get when you put a diffusion filter in front of your camera lens. The effect most people want is a general flattening/smoothing of the light, and reduction of fine detail (most notably, blemishes in people's skin), without ruining edges, which a regular blur would do. We do a relatively simple version, sometimes known as "white diffusion", where we first blur the picture, and then overlay it on the original using the original as a matte.
