1. With Luminar 4 open, click Creative icon.

2. Click on AI Sky Replacement.

3. Click on Sky Selection. You have an option to select preset sky.

4. This is the result of selecting Blue Sky 1.

5. You have many options to adjust the image. 

* Horizon Blending – Move this to the right to add a more gradual gradient between the sky and the rest of the image.

* Horizon Position – Allow you move the sky horizon up or down.

* Relight Scene – adjusts the tone and warmth of the image to give a more balanced and natural blend between your original image and the new sky. 

* Sky Global – pertains to spreading texture across the horizon if, for example, the sky does not fit the horizon properly.

* Close Gaps – slider fixes small details and holes that were not filled by the replaced sky initially (a common example is trees and between branches, leaves).

* Sky Local – the texture of the sky may not completely overlap with the original clouds and this slider is designed to correct it. In most cases, you don’t need it.

* Sky Defocus – adjust the sky look out of focus.

* Flip Sky – check this option the sky is flipped on its vertical axis. A good example is flipping the sun to the right or left of the frame.

* Sky Temperature and Exposure – this will allow you to fine tune the tone of your new sky.

6. You can select a sky by loading an image from your computer.
