Fog options

Among the few filter options, only Turbulence is somewhat important, because you can't change it later and have to undo and repeat the filter if the result doesn't fit your desire.

Layer name

The name of the layer. You can change it later in the Layers Dialog.

Fog color

Defaults to some kind of sandy brown (240, 180, 70). Click on the color button to change this if you think that is not the natural color of fog.

Turbulence

This is actually the Turbulence option of the Plasma filter: it controls the complexity of the clouds, from soft (low values) to hard (high values).

Opacity

The opacity of the layer. You can change it later in the Layers Dialog.
