Each time I’m in Barcelona, I roam the gothic section late into the night.
Around the main cathedral, there are rich opportunities for taking people photos set against ancient architecture. Once I get going, the hours fly by, and before you know, it’s time to get back to the hotel and crash. Anyway, the lady sitting on the steps is just one example of the Barcelona vibe at night.
The idea behind it is to make a scene more engaging by enhancing the sky. It cleverly replaces an uninteresting sky for another of your choosing. Anyone whose done this manually in Photoshop knows it’s a tedious chore to get right.
Luminar provides several dozen sky images with the tool; all you have to do is try one out. If you don’t like it, try another and keep experimenting until you find one you like.
In some scenarios, if it doesn’t recognize a sky in your image, the tool becomes disabled. For instance, if you take a picture of your foot, AI Sky Replacement is disabled. But if there is the sky in your image, it works more often than not. I’ve tried cases where I thought it wouldn’t work, and it does.
Also, there are sliders you can use to tweak the results, but it does the job with or without the sliders. As someone who spends a lot of time looking at details in images, it’s pretty good.
I won’t go into the arguments of what’s real and what’s fake. I create a lot of images, and I always manipulate them one way or another. I consider photographs straight out of the camera raw material. It is with this resource that I apply post-processing techniques to get the look and tell the story I have in my mind. In that vein, I have no compunction about using software (AI or not) to edit photos.
Over the years, I’ve taken many thousands of digital images that now sit in a Lightroom library. Less than one percent ever qualify for public consumption. Compositionally, most are just plain bad, but in a few cases, it’s because the sky is too flat.
I’ve started looking at some of these “reject” images with new eyes and asking myself, what if? What if it had a different sky and, perhaps, different lighting? Before I go on, let’s pause here because it’s the second part of this question that I find the most interesting.
Not only does it (as the name suggests) replace the sky, but it intelligently relights the scene to match the light from the new sky.
Think about that for a moment. If your scene was taken in midday, but the sky you’ve chosen as a replacement is from sunset, merely replacing one sky for another might create an unbelievable, if not odd, lighting contrast. As humans, we recognize subtle changes in light, even if we are not always aware of it. But combine a sunset sky with a noontime landscape, and we get a feeling that something is not quite right.
This is where the AI shines through. Skylums’s software agent works at relighting the non-sky elements with subtle tones of the sky that you selected. If Luminar simply replaced the sky, that would be a cool thing indeed, but Skylum is building upon years of AI experience. They’ve created a machine that combines the expertise of masking (sky replacement) with the techniques of expert toning. That is, given a scene, figure out how to achieve a believable lighting scheme. Of course, the idea of “believability” is subjective, and it depends on your individual preferences. All things considered, it does a pretty good job in a fraction of the time that you could do manually. There are infinite combinations of skies and landscapes, and each result is entirely unique. You could make the argument that it’s not perfect, but then, what or who is? The goal of AI is not perfection, rather accomplishment of things that formerly, only humans could do. In that regard, it’s as good or better and way faster than most humans.
In it, he explains just how far and fast AI is advancing. Stuart draws the curtain back on the future of our civilization once AI is fully realized. And from the sounds of it, we are much closer to that than most of us wish to believe. I recommend picking it up if you are the least bit interested in what the future holds.
Skylum’s Luminar is a fascinating tool, and it’s a little uncanny how well of a job it does. But as I’ve come to learn from Russell’s book, this is just the tip of the iceberg, everything is moving in this direction, and we’d all better get used to it. Children born today will never know a world without AI. Any doubts you may have are quickly dispelled the next time you look at your smartphone or ask Google a question.
So back to the photos, I’ve included some examples of both extreme and subtle applications. In the most extreme case here, the lighting of the ENTIRE scene is changed from daylight to night, as determined by my selection of one of Luminar’s out-of-the-box night skies. I added some additional elements like the light in the lighthouse and some extra toning. But the majority of the scene lighting is done by AI.
By now, I’ve used it in a lot of different scenarios, some extreme like the previous example, but more often, I use it in subtle ways. Examples of this are where I’m just adding a little bit of texture to a picture where the sky is only a minor background component, not necessarily to be noticed. Here are some examples of that.
There’s a lot to like with the combination of replacement and toning, but there’s one more thing that seals it, at least for me. Luminar supplies about thirty skies, from sunrise to the Milkyway galaxy, and everything in-between. So they basically give you enough of a selection for most situations. They also provide addition sky packs from accomplished photographers that you can purchase as plug-ins. But to be frank, I would prefer to use my own skies. And the one feature clinches the deal for me is that Luminar allows you to use your own skies.
As it happens, I take way too many pictures of the sky. Whenever I’m out shooting landscapes, and I see beautiful clouds, I can’t help but take a picture. By itself, an image of the sky is not that interesting; pretty maybe, but as far as being a complete composition, generally not.
It’s always been in the back of my mind that one day I’d do something with these images, and that time has come. All those skies I’ve collected can now be used in Luminar AI Sky Replacement.
I’ve started selecting a few and preparing them for use in the tool. I have morning, daylight, sunrises, and sunsets. I don’t have many night skies, so, for the time being, I’m using nights supplied by Luminar, and truth be told, those are the most fun to try out.
But I’m more of a sunrise and sunset person, so that’s most of what I have. Here’s a snapshot of the ones I’ve prepared so far.
With my old skies now ready, I’m going back over my archives and revisiting images. Luminar’s AI Sky Replacement is breathing new life into my library. Photos that would never make the cut are being reconsidered with some pleasant results. Anyway, if you’re into post-processing, give it a try. As for me, it’s become a permanent part of my kit. And, like it or not, this is a taste of the future, even as it is upon us now.
Crews recently finished working on the bridge. Only afterward did I realize what they were up to.
I photographed this from the adjacent south fishing pier. I was here early on a Sunday morning hanging out with some fishermen while I took a bunch of photos.
The colors are always changing, so I’ll probably post another one with a different color. I used Skylum’s Luminar 4 to process this. As part of that, I used the new AI sky replacement tool to add stars. Typically there’s too much light pollution to see the sky in all it’s glory. But in the days of AI, that’s no longer a problem, at least concerning post-processing.
This is a long exposure that I made using a tripod and an aperture of F-22. It’s a good thing it wasn’t windy; otherwise, the leaves would have come out blurry. Scenes like this are gratifying for me, and exactly why I love photography in the first place.
I took this a couple of weeks ago on a walk through the forest. Autumn came late this year, and only about half the trees had changed colors.
It’s pretty cool how the forest floor is carpeted with leaves while the afternoon sun shines through the trees. It was an amazing walk, and I was so happy to be in Maryland, which has all kinds of forest trails like this.
To get this photo, I held the camera close to the forest floor and used a small aperture; that way, both the foreground and the background are in focus. That same aperture setting is what causes the sun to give off the starburst-like rays.
Every afternoon at two, most French businesses close for a siesta. What that means for clueless foreigners like me is, no lunch.
The siesta, for me, has always been an abstract concept. However, now, I have first-hand experience. As we walked around French villages, we needed to be mindful of this custom. The best rule is to get up early, get out, and stop for lunch at a reasonable time. But getting up early doesn’t always work out when you’re on vacation, so thoughts of lunch get pushed out as well.
On more than one occasion, we’d see an enchanting little place like this, and think to stop for a taste of local cuisine: not during siesta. It’s the law, and if you think you’re going to starve, then pack a snack.
Here’s a random beach scene from Lloret de Mar. Everybody seemed to be having way too much fun for a weekday.
However, people here are on some kind of vacation, so the day of the week is unimportant. I had just arrived on a redeye from the states; it was Thursday, I think. And, I was just getting warmed up to the whole vacation thing.
What better way to do that than take photos of others who are already warmed up. Eventually, I got into the rhythm of things, maybe even a little too much. By the time we left this town, I had managed to lose my passport, but that’s another story for another day.
In this case, I was in the town of Sitges, walking around on a Sunday. I was next to the main church that sits along the sea. Sunday notwithstanding, nobody was going in or out, just tourists, like me, walking around it, taking pictures, and practicing leisure.
The colors are here in the Northeast, so a few days ago, I drove to this random park called Cunningham Falls; it turns out it’s not so random.
I don’t know the area, so; I picked a random place to visit on Google Maps. Little did I know this is a popular spot because there were a lot of other photographers that showed up as well. I took all kinds of shots from different angles, including this, which is a twelve-shot panorama.
