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.
