Change the Sky in Any Photo with AI Generative Fill
A perfect photo ruined by a dull, overcast sky is a common frustration for photographers, real estate agents, and travel content creators. bgeraser's generative fill lets you replace the sky in any photo with a stunning alternative. Mask the existing sky and the AI generates a new one that matches the lighting, perspective, and mood of your scene. Replace gray skies with blue, add dramatic sunset colors, create golden hour warmth, or generate stormy cloud formations. The AI blends the new sky naturally with the horizon line and existing scene lighting.
Step-by-Step Instructions
Upload your photo with the sky you want to change
Drop your photo into the upload area. Sky replacement works best on outdoor photos with a visible sky area: landscapes, real estate exteriors, travel photos, architectural shots, beach scenes, and any photo where the sky is a significant portion of the image. The tool accepts JPG, PNG, and WebP files up to 25 MB.
Select the generative fill tool and mask the sky
Switch to the generative fill tool and paint over the sky area. Cover the entire sky from horizon to the top of the image. You can use a large brush for broad sky areas and switch to a smaller brush along the roofline, treeline, or horizon where the sky meets the ground elements. A rough mask along the horizon is fine as the AI blends the transition naturally.
Generate the new sky
Optionally add a text prompt describing the sky you want: clear blue sky, golden sunset, dramatic storm clouds, pink cotton candy clouds, or starry night. If you do not provide a prompt, the AI generates a natural sky that complements the existing scene lighting. Click generate and the AI creates a new sky that matches the image's perspective, horizon angle, and lighting conditions.
Review and download
Check the horizon line where the new sky meets the ground elements. The AI typically blends this transition naturally, matching light direction and color temperature. If the result does not match your vision, generate again with a different prompt or adjust the mask. Once satisfied, download the final image with your new sky.
Tips for Best Results
For the most realistic sky replacement, match the new sky's lighting to the existing scene. If the photo has warm afternoon light on buildings, a warm sunset or golden hour sky will look more natural than a midday blue sky. The AI usually handles this automatically, but prompting with time-of-day context helps.
Real estate photographers can dramatically improve listing photos by replacing overcast skies with clear blue skies. This is a common and accepted practice in real estate photography that makes properties look more inviting without misrepresenting the property itself.
For dramatic landscape photography, try replacing a bland sky with stormy, moody clouds. The contrast between dramatic skies and well-lit foregrounds creates compelling images. Prompt the AI with descriptions like dramatic storm clouds approaching or golden light breaking through dark clouds.
Frequently Asked Questions
Does the AI match the lighting between the sky and the ground?
The AI analyzes the existing scene lighting (direction, warmth, intensity) and generates a sky that is consistent with it. The result typically looks natural because the AI considers the relationship between sky and ground lighting. For the best results, avoid extreme mismatches like placing a sunset sky on a photo with midday shadows.
Can I replace the sky in a photo that has trees or buildings at the horizon?
Yes. Paint your mask roughly along the tree or building line and the AI handles the transition. It blends the new sky behind tree branches, around building edges, and along irregular horizon lines. The AI is particularly good at maintaining the natural look of tree canopies against the sky.
Is sky replacement considered photo manipulation?
Sky replacement is a common and widely accepted practice in real estate photography, travel marketing, and landscape photography. It is considered standard post-processing rather than deceptive manipulation, as it enhances visual appeal without misrepresenting the subject. For journalistic or documentary photography, sky replacement would be considered inappropriate manipulation.
Can I add a night sky or starry sky?
Yes. Use a prompt like clear starry night sky or milky way night sky when generating the fill. The AI will generate a dark sky with stars. Keep in mind that the foreground should be compatible with night lighting for the most realistic result. Daytime foregrounds with night skies create a surreal, artistic effect rather than a realistic one.
