How to Create Star Trails in Photoshop Using Actions

Do your landscape photos lack star trails? Maybe the weather wasn’t cooperating, or maybe your camera isn’t the finest at photographing long exposures, and if that’s the case, don’t worry because you can still produce star trails in Photoshop that look realistic.

The best part is that this effect only requires one image.

In this lesson, I’ll teach you how to effortlessly generate star trails in Photoshop.

In this tutorial, I’ll be using Photoshop 2022 but any version will work.

Next, press CTRL + S to save and exit out the window.

So far your image should look like the image below.

Step 3: Let’s Make Some Adjustments

First, let’s add a Layer Mask to the top layer then press CTRL + I to invert that mask.

By inverting the mask, the star trails will disappear but don’t worry we’ll bring them back.

Next, press B and select a Soft Round Brush. Make sure the foreground color is set to white.

Set the Opacity and the Flow of your brush to 100%.

We can now bring back the star trails by painting in white on our Layer Mask.

Only paint the sky and go around the person by adjusting the size of your brush.

Do not paint the ground.

If you need to erase some of the Stars Press X to change the foreground color to black. (White makes the stars to show, black makes them disappear)

The top of your Layer Mask should be white and the bottom should be black.

To finish our project we’ll add 1 adjustment layer.

First, go to your Layer Panel and add a Color Balance Adjustment Layer then, set the Midtones, Shadows, and Highlights as shown below.
