9.1.1. AI Sky Replacement Guidelines

In order to achieve the best results with Luminar 4’s AI Sky Replacement tool, it is suggested that you follow

these guidelines. Doing so will give the application the most information and ensure best results. While the

filter includes sample skies for you to use, many will want to use sky photos of their own creation.

Technical specifications

In order to use a texture with the AI Sky Replacement filter, it must meet these technical specifications:

1. Make sure the file is of adequate resolution. This means a minimum of 1,200 pixels on the shortest

edge. Higher resolutions are preferred.

2. The files should be saved in the JPEG format. You can export an image as a new JPEG file in

Luminar by choosing File > Export and choosing the JPEG format. You can use a quality setting of

60–85 to keep file sizes smaller.

3. Keep the image size below 10 megabytes for the optimal performance of the tool.

How to capture sky textures

Luminar 4’s sky replacement technology requires sky texture to be photographed in a specific way to

achieve realistic results. You can also pre-process existing sky images to better meet these guidelines and

export new JPEG files for use by the filter.

Best practices

Use the following guidelines for best results:

• Sky texture should have a certain orientation. Make sure that the bottom edge of the photo is

aligned with the horizon. The top part of the image should be oriented toward the zenith.
