Creating new skies with AI Sky Replacement

“

- Sometimes as you work with images, there may be no sky to enhance. Maybe it was a really clear day, or a really overcast one, and the sky is just boring. Well, thanks to the AI Sky Enhancer, we can target the sky using similar technology that was in place with Sky Enhancer, but completely swap it out with a new sky. Let me show you. Let's start with this image here, that has both in focus and out of focus areas. And I'll switch to the edit tab and choose "creative." From the AI sky replacement, I can choose from a variety of built-in skies. You'll see as we pick each one, it's going to change the sky that's there. And even the out of focus areas, the soft transition here on the railing is handled correctly. You see with each change it automatically adjusts. Now in this case, we used blue sky number 4. And what you'll notice is that the angle and the alignment to the horizon has been properly handled. Let's pick a different image for a moment, and you'll see when we choose the same blue sky number 4, that it automatically scales and picks up on different details of the photograph, making it have a different look here as it correctly composites. Now one of the things that I like is that we could adjust the relight scene command. This will take the color of the new sky and easily apply it. So if we go with something like a sunset image, you'll see that it starts to pick up that new color. We also, using the advance controls here, can play with options for sky global and sky local so that we don't add too much transparency. In this case I want to minimize so that this just picks up the reflections, but doesn't become transparent because of the strong blue sky reflected in it. If we toggle that on and off, you see that the new sky is easily composited in, and the color matches. Let's choose one more image here and try something a little different. This time I'm going to load my own sky. So I could just chose load custom sky image. Now I simply need to navigate to the folder and select a JPEG. All you'll want to do is crop it so it has a straight horizon. You can use any JPEG file that you have, or download stock images that you have the rights to. You see that it automatically angles and adjusted to the scene. I'm going to use the relight option here and take advantage of some other options under advance, like flip sky which allows me to change the direction. I actually think that looks a bit better. Let's put a little blend on the horizon there as well as tweak the position. And you see we can move that up or down and it smoothly composites. Now what's really quite amazing about this is how well it's handling the complex areas. If you look over here to things like the crane, you see that it correctly handled the advanced transparency, as well as the gaps in between the buildings. Now once you have this basic element composited, just switch back to the controls that you learned about earlier. You can use accent AI to even things out, or even sky enhancer to enhance the sky that you've replaced. AI structure, which we'll discover more in a moment, easily adds in depth and detail, particularly useful in a skyscape. That's looking really good. And as I take a look through here, I could take advantage of even changing the color temperature of the sky, or its overall exposure to brighten it or darken it. Once satisfied, select the rest of the images, and you could choose "adjustments," "sync." It will automatically go through and add in the new sky and blend it with the new photograph. It'll take a moment for each image to decode, but you'll see that it takes the new settings and easily applies them in.
