Hi,

This is my first post on the site and it is a tutorial so here we go:

1. Create a new picture (File>New) Set dimesions to 500x500 (pixels).

2. Filter>Render>Clouds

3. Filter>Render>Difference Clouds

4. Image>Adjustments>Invert (Ctrl+I)

5. Image>Adjustments>Levels (Ctrl+L). Set input levels to: 0 0.10 255
Now click ok.

6. Finally go to Image>Adjestments>Hue/Saturation. Set to: Hue 238 Saturation 50 Lightness 0.

Final Product:


Hope you like it!
