A great landscape can be ruined by a flat grey sky. Sky Replacer
detects the sky region in your photo and swaps it for a more dramatic one — sunset,
milky way, aurora, storm clouds — and re-balances the lighting on the ground so the
composite looks natural, not pasted.
Built-in sky presets
Golden hour sunset
Blue hour twilight
Milky way with stars
Storm clouds + lightning
Aurora borealis
Pink pastel dawn
Cloudy magic hour
Or describe your own ("apocalyptic red sky with smoke") and the model will generate
a custom one.
Frequently asked questions
What if there are trees or buildings cutting into the sky?
The AI handles complex sky-line masks (trees, power lines, mountains) well. For very fine detail like single leaves we recommend a touch-up after — but in 90%+ of photos the auto mask is clean.
Will the ground lighting match the new sky?
Yes — the model re-grades the foreground to match the sky's colour temperature. A sunset sky warms the ground, an aurora sky cools it. Premium users can disable this if you want only the sky changed.
