Here’s an example where Luminar correctly identified the sky through an arch. I’ve tried cases where I thought it wouldn’t work, and it does. But if there is the sky in your image, it works more often than not. For instance, if you take a picture of your foot, AI Sky Replacement is disabled. In some scenarios, if it doesn’t recognize a sky in your image, the tool becomes disabled. If you don’t like it, try another and keep experimenting until you find one you like. Luminar provides several dozen sky images with the tool all you have to do is try one out.

Anyone whose done this manually in Photoshop knows it’s a tedious chore to get right. It cleverly replaces an uninteresting sky for another of your choosing. The idea behind it is to make a scene more engaging by enhancing the sky.

Lately, I’ve been using the AI Sky Replacement tool inside Skylum’s Luminar 4.
