If your photo lacks a compelling sky, the SkyAI tool makes replacing it easy. This tool is designed to work with flat or blown out skies but can be adjusted to work with most skies by refining the sliders. Using the power of Artificial Intelligence, SkyAI automatically analyzes an image identifies where the sky begins and ends, then seamlessly replaces the sky to create a realistic look.

Standard Settings

  • Sky Selection. Use this drop-down menu to choose from a library of sample skies to get familiar with the SkyAI tool. You can load your own skies by choosing the Show Custom Skies… menu option. See this article for more details on using your own skies with SkyAI.
  • Horizon Blending. This slider smooths the transition between the current horizon and the new one. Since there is often a soft transition, using a higher value often results in a more photo-realistic look.
  • Horizon Position. LuminarAI attempts to automatically align the horizon of the original photo with the horizon in the new sky. You can override this alignment and shift the image up or down to taste.
  • Relight Scene. The SkyAI tool relights the entire photo so the lighting and colors of the original image match the lighting and colors of the replacement sky. This slider adjusts the intensity of the relighting effect.
  • Sky Global. This slider affects how the texture is mixed into the scene. A higher value will increase the amount of new sky that is added.

Advanced Settings

  • Close Gaps. This slider fixes small details and holes that were not initially filled by the replaced sky. You may need to adjust this if the image has fine details such as trees or wires.
  • Sky Local. This slider is useful to control the overlap of the new sky with the original clouds. It’s designed to influence how much the original clouds are replaced.
  • Sky Defocus. This slider defocuses the sky and is useful when a shallow focus is used with a foreground object.
  • Flip Sky. This option will flip the new sky to change the direction of the sky replacement image. It’s useful when a photo has shadows that you’re trying to match.
  • Atmospheric Haze. Use this slider to add a soft haze to the sky. Haze is useful for matching a replacement sky to the original image, especially if there’s moisture in the sky or environmental pollutants.
  • Sky Temperature. Use this slider to warm or cool the new sky to match your needs.
  • Sky Exposure. This slider controls the exposure of the replacement sky and allows you to easily change the image’s look and feel.
