Our general method is to use the fiber, wind and other functions in the filter to achieve the above intention.
1. Create a new file, click Filter, and use the fiber function.
2. Use hurricane 10-15 times (shortcut key Ctrl+F).
3. Rotate the canvas.
4. Press the shortcut key Ctrl+F twice
5. Rotate the canvas clockwise and press the shortcut key Ctrl+F 1-2 times. The purpose is to restore the trajectory produced when the water splashes. Then, we began to adjust the shades, color, and use techniques such as deformation, liquefaction, and repair according to our own creative intentions.
Of course, you have more methods and there are many masters. I'm just here to provide an idea and share my experience.
