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.
