FAQ

To replace the sky in a photo, upload your image to Luminar on Web, open Sky AI, and choose a new sky. The AI detects the existing sky, replaces it, and adjusts the lighting to match your scene. You can change the sky in your photo in just a few clicks, without complex manual editing.

Sky AI is designed to blend the new sky with your photo and adjust the lighting for a cohesive result. It also works to preserve details along the edges of buildings, mountains, and other objects. For the most natural look, choose a sky with lighting and colors that complement the original scene.

You can choose from a variety of skies, including clear blue skies, colorful sunsets, dramatic clouds, and atmospheric night skies. Whether you want to add a sunset to a photo, add clouds to a photo, or create a completely different mood, Sky AI helps you transform the scene in just a few clicks.

Yes. Sky AI is designed to detect complex edges, including tree branches and other fine details, to blend the replacement sky into your photo. Results may vary depending on the image, especially when branches overlap with a similar-colored sky, but AI helps preserve intricate details for a more natural-looking result.

Luminar on Web lets you replace skies directly in your browser without installing software. Luminar on Desktop offers a more advanced workflow, including RAW photo editing and batch processing, so you can apply consistent edits across a series of photos. It's a great choice for photographers who want more control over their images and need to edit multiple shots efficiently.
