How to replace the sky in a photo

An overcast white sky ruins an otherwise great shot — the flat, featureless gray or blown-out white saps energy from landscapes, real estate exteriors, and travel photos. Magic Eraser's AI replaces the sky while adjusting foreground lighting to match, creating a natural composite.

Why sky replacement requires more than just swapping pixels con Magic Eraser

The sky isn't isolated from the rest of the image — it illuminates everything below it. A golden hour sky casts warm light on buildings and faces. An overcast sky creates soft, diffused shadows. When you replace the sky, the foreground lighting must change to match, or the result looks fake. Manual sky replacement in Photoshop involves masking the sky (complex around tree branches, hair, and architectural detail), placing the new sky, then adjusting foreground color temperature, brightness, and shadow direction to match the new sky's implied lighting — a process requiring 20-45 minutes for a convincing result. Magic Eraser's AI handles the full process: precise sky masking even around fine detail, sky replacement, and automatic foreground lighting adjustment.

Istruzioni passo passo

1. 1

   Upload the photo

   Open Magic Eraser on web, iOS, or Android. Upload the photo with the sky you want to replace — an overcast landscape, a white-sky real estate exterior, a travel photo with a dull or blown-out sky. JPEG, PNG, HEIC, and WebP supported.

2. 2

   Brush the sky area

   Paint over the sky. The AI automatically detects the sky boundary, handling complex edges like tree branches, building silhouettes, and horizon details. You don't need to trace the boundary precisely — brush broadly over the sky area and the AI identifies the exact edge.

3. 3

   Generate and review

   The AI replaces the sky with a contextually appropriate alternative — typically a natural blue sky with clouds that matches the scene's lighting direction and time of day. The foreground is subtly adjusted to match the new sky's illumination. Check the horizon line and tree/building edges for clean transitions. Export at full resolution.

Ideale per

• Real estate photography where overcast skies make exteriors look flat and uninviting
• Landscape and travel photography where an overcast or blown-out sky lacks drama
• Outdoor event photography where the sky is white or featureless in group shots
• Architectural photography where a dramatic sky enhances building composition
• Tourism and hospitality marketing where blue skies convey warmth and appeal

Consigli per risultati migliori

The AI produces the most natural results when the original sky is clearly separated from the foreground — a distinct horizon line with clear sky above and landscape/buildings below. Complex silhouettes (tree branches, construction cranes, power lines) are handled well but benefit from a clean brush stroke that covers the full sky area. For photos where the sky is very bright (blown-out white) and the foreground is properly exposed, the AI has a clear boundary to work with. For photos where the sky brightness blends gradually with the foreground (hazy horizons, fog), results may require a second pass near the transition zone. The AI chooses sky types that match the scene — it won't place a sunset behind a scene lit from the front.

Domande frequenti

Does the foreground lighting adjust automatically?

Yes. When the AI replaces a gray overcast sky with a blue sky, it subtly warms the foreground tones to match the implied lighting change. This automatic adjustment prevents the mismatched-lighting look that makes manual sky swaps obvious.

Can I choose a specific sky?

The AI generates a contextually appropriate sky based on the scene. For specific sky styles, the generative fill tool gives you more control over the generated content.

Does it handle tree branches against the sky?

Yes. Fine detail like individual tree branches, leaves, and architectural elements against the sky are masked precisely by the AI. This is one of the hardest parts of manual sky replacement and where AI excels.

Is sky replacement free?

Yes. Sky replacement using the brush tool is available on the free tier with daily usage limits. Premium removes limits for professional real estate and landscape workflows.
