# Sky Replacement
Sky Replacement lets you swap out a dull or overexposed sky with a more dramatic one — blue skies, sunsets, storms, and more. Luminar detects the sky automatically and blends in a new one using AI.
Key points of this tool:
* **Sky Selection** – Choose from built-in skies.
* **AI Detection** – Automatically identifies the horizon and sky edges.
* **Edge Refinement** – Ensures natural transitions between sky and foreground elements like trees or buildings.
* **Lighting Match** – Adjusts the scene’s lighting to match the new sky for realism.
* **Reflections** (when available) – Simulates sky reflections in water or glass.
**How to Use:** Tap the sky icon, select a sky from the library, and Luminar will automatically blend it into your photo with adjusted lighting and edge transitions.
**When to Use:** Ideal for travel and outdoor photography, especially when weather conditions didn’t cooperate or you want a more eye-catching backdrop.

#### Sky Adjustments
Click **Adjust** at the top of the selected sky in the scrollable panel to refine the position of the new sky. Hold and drag the slider to move the sky horizontally or vertically. To make more precise corrections of the position, tap the dots around the circle to move the sky accordingly.
Scroll the panel to the right to access additional controls:
* **Brightness** - adjust how bright or dark the sky appears.
* **Warmth** - make the sky cooler or warmer in tone.
* **Defocus** - slightly blur the sky for a more natural depth effect.
To adjust the masking of your sky, use the following sliders:
* **Global** - controls the overall strength of the sky mask.
* **Close gaps** - fills in small unmasked areas, especially around fine edges.
* **Fix details** - improves blending around trees, buildings, and other complex details.
#### Custom Skies
To add your custom sky, click on the cloud with a plus on the left side of the list. Your gallery will open. Navigate to the file that contains the sky you want to use in the photo. Click on the trash bin to delete the sky.
