All of the colors produced by Plasma are completely saturated. Sometimes the strong colors may be distracting, and a more interesting surface will appear when you desaturate the image using ColorsDesaturate.

“Plasma” filter options

Preview

If checked, parameter setting results are interactively displayed in preview.

Random seed

This option controls the randomization element. The Randomize check-button will set the seed using the hardware clock of the computer. There is no reason to use anything else unless you want to be able to repeat the exact same pattern of randomization on a later occasion.

Turbulence

This parameter controls the complexity of the plasma. High values give a hard feeling to the cloud (like an abstract oil painting or mineral grains), low values produce a softer cloud (like steam, mist or smoke). The range is 0.1 to 7.0.

Clipping

Het resultaat van dit filter kan groter zijn dan de oorspronkelijke afbeelding. Met de standaardoptie Adjust wordt de grootte van de laag automatisch aangepast wanneer het filter wordt toegepast. Met de optie Clip wordt het resultaat bijgesneden tot de laaggrens.
