In this tutorial, I will show you how to paint starfield by using a custom brush and also a quick way to "generate" starfield in Photoshop by using noise.

First, lets create a custom stars brush for Photoshop. These are the steps on how to create star brush in Photoshop.

Shape Dyamics
  • Size Jitter - Randomise brush tip size. Control with Pen Pressure.
  • Minimum Diameter - Minimum brush tip size.
  • Angle Jitter - Randomly rotate brush tip.
  • Flip X Jitter - Randomly fliping brush tip in X axis.
  • Flip Y Jitter - Randomly fliping brush tip in Y axis.

Scattering
  • Scatter - Randomise brush tip location. Enable Both Axes so it scatter on X and Y axis.
  • Count - Number of brush tip scatter. Default 1 is good enough



Saving The Brush Settings

After changing all the brush settings, we will need to save it again via New Brush Preset in the brush panel. If we don't do this, we will lose all the settings! Then under the brush panel again, choose Save Brushes to backup your whole set of brush.

  • Adjust the levels so some noise are bright and some are dim. Refer to image above.
Currently, the generated stars still appear evently in the whole image. We will need to change it so certain part will have star clusters, and some part have will less stars.

After you are done adjusting the star layer, set its blending mode to screen and it will look something similar to this.

Add a layer with screen or add blending mode. Then use the star brush we created earlier to add more stars in the scene. I usually use the brush for bigger stars.
