Click Filter → Noise → Add Noise. In the window that opens, set the appropriate number and select the "Gaussian Distribution" item. When the settings are complete, click OK to apply the settings.

Then we simulate the lighting effect and add the halo effect. Click Filter → Rendering → Lens Halo, and set appropriate parameters according to the effect.

We can also change the color of sand to imitate the lighting effect of different colors. Click Image → Adjust → Replace Color. In the replace color window, first use the color eyedropper tool to get a certain color of sand from the drawing area, then set an appropriate color tolerance, and finally change the color of sand by adjusting the hue.

Simulation of the production of strokes, because there are two ways to make sand painting, one is to accumulate sand for painting, the other is to leave blank for painting, so we need two types of strokes. Create a new layer and set its blending mode to Dissolve.

Click the "Set Default Background Color" button in the toolbar to set the foreground and background colors as the default black and white. (shortcut key d)

Click "Stroke Tool", and then press "F5" on the keyboard to open the settings panel and select a brush tip type. Bian Xiao thinks that the accumulation effect should use the "drip bottom" brush.

To switch and use brushes, click the Brush tool, click the Change Brush button on the Property Bar, and then set the Brush View Mode to Large List.

Then you can make full use of these tools to create. As long as you have imagination, you can achieve the desired effect.
