Just like the day-time image, export the edit as a different JPEG file.įirst, lets undo the edit we have done for the night-time image by going to the History tab in Luminar, and select the action right before the AI Sky Replacement. Here is a before/after comparision of the edits we just did. I applied a -4 EV exposure and decreased contrast. Go back to the Essentials tab and adjust exposure so that the scene looks realistic. Increase the Atmospheric Haze slider to have the contrast in the stars match roughly to the distant scenery. Use the Relight Scene slider to adjust how much AI relighting are to be applied. Also notice that its own scene relighting did a fairly good job of matching the colors fo the lake and the mountains with the sky. Open up the Advanced Settings panel and use the Sky Global slider to refine the threshold of where Luminar thinks the sky is. In this case I’ve chosen the “Starry Sky 2” as a replacement. I go to the Creative tab in Luminar and apply the AI Sky Replacement tool. Now let’s create the night version of the same photo. Once we’re happy with the edits, export it as a JPEG. For my image, I increased the contrast and structure sliders to make the mountains look more dramatic I also increased vibrance and dehaze sliders to make the distant sceneries and clouds “pop”. In Luminar, apply any post-processing edits are needed. Any photo manipulator like Photoshop or Pixelmator should work fine. The hard edges of the horizon and mountain lines should make the sky replacement process mostly automatic. Here, from my Photos library, I picked a dramatic photo taken by Jackson Lake, WYO. I also prefer this image to a be a day-time image as default. Preferably this is a landscape image with clearly defined horizon so that Luminar AI could do its sky replacement easily. Using Image Manipulation Programs to Create Scenes □ Part One: Dayįirst, I go to my photo library and pick a photo I would like to be my wallpaper. HEIC file which we can then set as desktop wallpaper in macOS. We will then export each scene as a different image, and upload all of them to a website called Dynamic Wallpaper Club, which will combine all the images into a single multiframe. The AI further performs scene relighting in other parts of the image such that the whole image looks convincing - color and light wise. Then the segment mask can be used for a sky substitution. I use Luminar 4.3 for its recent AI Sky Replacement feature - which uses machine learning to segment skies from other parts of the image. Luminar 4, Photoshop) to edit-in the scene at different times. So instead I will take an existing photo I took as a default day-time image, then use image manipulation programs (e.g. One could achieve this by having enough patience to camp outside and take a photo once every few hours. To ensure that the dynamic wallpaper can seamlessly transition between images, the day and night time images must be in the same position with the same point of view. In this post, I will provide a step-by-step guide to creating custom 24-hour cycle (or day/night cycle) dynamic wallpapers for macOS. Also these wallpapers don’t refresh when the computer is asleep or off, causing the wallpapers to be out of sync once powered on again. While traditional “dynamic” wallpapers exist where a folder of images can cycle every set period (30 min, 1 hr, etc.), they don’t work well as they don’t respond corresponding to the environment (such as sunrise and sunsets). Using Image Manipulation Programs to Create Scenes HEIC file with added metadata such as GPS or time information used to determine when to transition to the next image. These set of images are packed into a single multi-frame. How it works is that the wallpaper dynamically changes based on current time or sun positions using a set of images, typically taken at the same location with the same viewpoint, but at a different time. Since macOS Mojave (macOS 10.14), dynamic wallpapers have become one of my favourite things about the OS aethetics.
