ps kusansui

Quick answer：

Kusansui, also known as 'dry landscape' or 'rock garden,' is a traditional Japanese garden style that emphasizes the use of rocks, sand, and moss to represent a natural landscape without water. In Photoshop, 'PS kusansui' might refer to creating a kusansui-inspired design using digital tools. To do this, one could use Photoshop's layer techniques to arrange stones, apply textures to simulate moss, and use brushes to create ripples or waves in the sand.
