Perlin noise generates pixels with values that vary between the foreground and background colors, resulting in a cloud pattern. Sometimes known as Clouds or Difference Clouds. It can be used to create realistic looking scalable textures, including cloud, smoke, and rock or earth-like effects, and is a great way of adding realism to textured areas.
This filter can be found in the Filters panel.
When the filter is applied, the clouds are generated using the currently selected background and foreground colors. The image data on the active layer is replaced.
The following settings can be adjusted on the vertical sliders:
Octaves—controls the cloud complexity.
Zoom—controls the zoom level of the clouds and the complexity of the noise.The following settings can be adjusted on the context toolbar:
Split—enables the Before and After view. When toggled, it presents filter application side by side.
Apply—applies changes made.
Cancel—cancels changes made.
