1. How to Create Nebula Effect Photoshop Brushes
Let's start to create our galaxy in Photoshop by setting up a new document with a size of 2000 x 2000 px.
Select the Background layer and press Control-J to create a duplicate, and then go to Filter > Render > Clouds.
Go to Image > Adjustments > Brightness/Contrast and set the Brightness to -90 and Contrast to 95.
Then go to Filter > Noise > Add Noise and set the Amount to 20%, Distribution to Gaussian, and put a tick on Monochromatic.
After that, go to Image > Adjustments > Levels and set it to the following settings: 125, 1.00; 255. (The numbers may depend on your picture, so play with the settings until you get something like star clusters.)
Now we need to pick the Lasso Tool and select the part of the texture that will be our galaxy brush. Once you've finished selecting, press Control-J to create a copy of the selection.
Make all the layers except the last one Invisible, and then select it and hit Control-I to invert the colors.
Add another Brightness/Contrast adjustment to both, setting set the Brightness to about 80 and the Contrast to about 60.
Make sure that all the layers except the last one are Invisible. Then go to Edit > Define Brush Preset, select a name for your brush, and hit OK.
Now we need to create a new layer with Shift-Control-N and then add a stroke with our brush. As you can see, our galaxy brush is almost invisible, and there is no glow effect. We will fix it in the next step.
Double-Click on the layer and select Outer Glow, using the following settings:
- Blend Mode: Screen
- Opacity: 100%
- Color: White
- Spread: 3%
- Size: 16 px
Now Right-Click on the layer and select Rasterize Layer Style. Invert the colors with Control-I, and finally Define Brush Preset, as we did before, to create a new brush.
You can see what our brush should look like below. Try to create a few similar brushes the same way by using different cutouts with the Lasso Tool.
2. How to Create a "Stars" Brush
If you want to learn how to create a galaxy in Photoshop, you'll definitely want to create a stars texture. Let's start by creating a new black layer and then Add Noise with the following settings:
After that, go to Filter > Blur > Gaussian Blur and set the Radius to 3.
Let's go to Image > Adjustments > Threshold and set the Level to 30.
Select a part of the texture with a bunch of "stars" using the Lasso Tool, and then press Control-J.
Make all layers Invisible, except the new one, and then hit Control-I and Define Brush Preset.
And finally, go to Brush Settings and set the Size Jitter and Angle Jitter to 100%, and set the Scatter to 574%.
3. How to Create a Nebula Pattern Photoshop Background
Now, it's time to combine all the brushes and add some more effects to create a realistic galaxy background. Let's create a new layer above the black background and then add a few strokes with the "stars" brush.
After that, increase the brush size and add a few more strokes of stars, and then repeat it a few times.
Double-Click on the layer and add an Outer Glow with the following settings:
- Blend Mode: Screen
- Opacity: 75%
- Spread: 3%
- Size: 9 px
Create a new layer and use our "galaxy" brush on it. Double-Click on the layer and add an Outer Glow with the settings we used in the previous step. Then click on Gradient Overlay and use the following settings:
- Blend Mode: Hard Light
- Opacity: 50%
- Angle: -90.
Create a new layer and fill it with black using Shift-F5, and then go to Filter > Noise > Add Noise and set the amount to 20%.
Change the Blending Mode of this layer to Screen and the Opacity to 40%. This will add a realistic look, since space images often have a lot of noise on them.
Let's add some color correction to finish our space background. Go to Layer > New Adjustment Layer > Levels and change the settings to 35, 0.56, 236.
And for the final step, let's create a Curves adjustments layer with the settings you can see below:
