BraveCLHow to create a cosmic sky on Mac
Import a landscape, add a violet nebula and blue planet, fine-tune their appearance, and compare the cosmic result in Galaxy Studio on Mac.
- What you'll achieve
- You will have a mountain photo with a violet nebula and a blue planet positioned above the landscape, with subtle bloom and a side-by-side comparison showing the change.
- What you need
- Galaxy Studio - Photo Effects 2.0 installed on a Mac.
- A landscape photo you have permission to edit. This demonstration uses a mountain landscape.
Galaxy Studio can blend a cosmic sky into a landscape without replacing the entire photo. This walkthrough reproduces its first Mac App Store screenshot: a mountain scene with a violet nebula and a blue planet, followed by an original-versus-edited comparison.
1.Import a landscape photo
Open Galaxy Studio, then choose your landscape in Source photo. The mountain image appears on the editor canvas before any effects are added.
Galaxy Studio shows the imported mountain landscape in the Source photo editor. 2.Add a violet nebula
In the built-in catalog, choose the Nebula category and select Violet Haze from Catalog asset. The nebula becomes the first applied texture over your photo.
A violet nebula is layered over the mountain landscape in Galaxy Studio. 3.Place a blue planet
Switch to the Planets category and choose Blue Giant from Catalog asset. The scene now contains one texture and one celestial object.
The Galaxy Studio editor shows a blue planet added to the nebula scene. 4.Move and size the planet
Select the planet with Select last celestial. In its inspector, adjust Horizontal Position to 0.73, Vertical Position to 0.26 and Scale to 0.17. The planet sits in the open sky without covering the mountain.
The blue planet is positioned in the open sky with its position and scale inspector controls visible. 5.Review the light balance
Review the full cosmic composition after the lighting adjustment. Check that the violet sky and blue planet still leave the mountains, trees and original landscape clearly recognizable. The next step shows the comparison.
Galaxy Studio displays the layered cosmic scene after subtle photo bloom is applied. 6.Compare the original and cosmic scene
Click compare to view the original landscape alongside your nebula-and-planet edit. Inspect the result before preparing the final image.
Galaxy Studio compares the original mountain photo with the edited cosmic sky composition.
Tips
Use the open sky to position the planet away from the most important foreground details.
The comparison view helps you judge whether the overlay and bloom preserve enough of the original landscape.
Galaxy Studio edits one photo at a time; you can repeat this workflow on another image.
Watch outThe Skyline boundary is manual; Galaxy Studio does not automatically replace the sky or perform fine-detail masking.
Watch outThe comparison view is for reviewing the edit. Saving or sharing the finished photo is a separate step.
