9.1. AI Sky Replacement Tool
If your photo lacks a compelling sky, AI Sky Replacement makes replacing it easy. The tool is designed to
work with flat or blown out skies, but can often be adjusted to work with most skies by refining the sliders.
Using the power of artificial intelligence, the AI Sky Replacement tool automatically analyzes an image,
identifies where the sky begins, and ends, then seamlessly replaces the sky to create a realistic look.
Standard Controls
Sky Selection. Choose from a library of sample skies to get familiar with the tool. Be sure to load
your own skies as well by choosing the *Load Custom Sky Image *option. See this article for more
details on using your own skies.
Horizon Blending. This smooths the transition between the current horizon and the new one. Since
there is often a soft transition here, using a higher value is often more photo-realistic.
Horizon Position. Luminar attempts to automatically align the horizon of the original photo with the
new sky’s horizon. You can override this alignment and shift the image up or down to taste.
Relight Scene. The AI Sky Replacement tool relights the entire photo so the lighting and colors of the
original image match the lighting and colors of the sky. This slider adjusts the intensity of the
relighting effect.
Sky Global. This affects how the texture is mixed into the scene. A higher value will increase the
amount of new sky that is added.
