What Galaxy Studio does

  • Move the sky boundary by hand

    Drag handles along the horizon and set Feather, Horizontal Position and Vertical Position to decide where the sky meets the foreground.

  • Match a celestial object to the scene

    Select an object and adjust its exposure, temperature, tint, glow and light spill with Light Match.

  • Compare three variations

    Try three temporary variations side by side, keep the one you like and save it as a Personal Look for another photo.

  • Add objects from the built-in collection

    Place nebulae, stars, aurora, galaxies or planets from the built-in Effects collection.

Questions

Does it change my original photo?

The original image is not stored inside a saved Personal Look, so the look can be applied to another photo.

Can it edit several photos at once?

No. Galaxy Studio edits one photo at a time. Batch editing is not included.

Does it replace the sky automatically?

No. Skyline is a manual sky boundary, not automatic AI sky replacement or fine-detail masking.

Can I edit the layers later?

No. Editable layered projects are not included.

What's new

Version 2.0 · 30 Oct 2026

Version 2.0 lets you shape a cosmic scene from your own photo. Edit the horizon by hand, match the light of selected celestial objects, compare three variations and save looks to reuse on other photos. Set the final frame, then preview the image and file details before saving or sharing PNG, JPEG or TIFF.
