"subject": "three rock islands floating in the air above a valley, each one with a base shaped like an upside-down cone of chipped grey stone and a flat top covered in scrub and a grove of pines with wide, flattened crowns; from each base falls a thin vertical waterfall, white and straight, that dissolves into mist before it reaches the ground; the largest island sits in the center, well above the horizon, and the other two, smaller, sit lower, one on the left and one on the right, at almost the same height",
"scene": "a mountain valley seen from the top of a stone lookout: in the middle of the frame a wide lake of still water, ringed by dense dark green forest and cut by arms of river that vanish toward the horizon; horizontal bands of white mist lying over the woods between the lake and the mountains; in the background, layers of sharp pointed peaks, each layer lighter and more faded than the one in front; in the foreground, cracked slabs of lichen-covered rock taking the bottom band, with low shrubs and two twisted pines coming in from the left and right edges, leaning into the frame",
"composition": "vertical image in 3:4 ratio; the horizon line a little below half the height; the big central island fills the upper third and lines up with the sun; the lake in the middle third; the stone lookout takes the bottom quarter; the moon in the top right corner, without touching the edge",
"camera": "wide angle, high vantage point, at the edge of the lookout and aimed slightly down over the valley, with the horizon near the middle; everything in focus, from the rock in the foreground to the peaks in the background, with no blur at all",
"lighting": "a low, small sun, right in the center of the frame and almost touching the mountain line, backlight that lights the mist from inside and opens a path of golden reflection on the water of the lake; the islands and the peaks take only a thread of warm light on the edges turned toward the sun and stay darker on the near side; strong atmospheric perspective, each layer of mountain more washed out than the one before",
"color_palette": "gold and amber in the band of the sun and in the reflection on the lake, orange and salmon in the clouds, deep blue at the top of the sky, moss green and dark green in the woods, stone grey on the islands and the peaks, milky white in the mist and the waterfalls",
"materials": "chipped lichen-covered rock on the islands and the lookout, dense pine foliage, the still mirrored water of the lake, thick milky mist, atomized spray in the waterfalls",
"style": "realistic fantasy digital art, high-detail cinematic matte painting, rich saturated wallpaper colors, an epic and quiet late-afternoon mood",
"details": "preserve the three floating islands with one waterfall each, the grove of pines on top of each island, the small sun in the center of the horizon, the path of golden reflection crossing the lake, the horizontal bands of mist over the woods, the big sharp moon with craters at the top right and the rows of clouds lit from below",
"negative_prompt": "people, animals, creatures, dragons, spaceships, castles, buildings, roads, bridges, boats, text, letters, numbers, watermark, signature, logo, drawn frame, HDR halo, blown-out sky, background blur, AI artifacts"

How to use
A good free wallpaper usually comes small, over-compressed and with a watermark on it. This prompt builds the whole scene from scratch, in 3:4, and you take the crop you need out of it. It works in ChatGPT, Gemini and NanoBanana.
1. Paste the prompt without sending any image: it describes the whole scene.
2. Happy with it? Ask for the same scene in 9:16 for your phone. The 3:4 is the one for a computer and for a printed frame.
3. For a phone screen, also ask for "nothing important in the top third": that is where the clock and the icons sit.
4. Change the hour and you get another image: "in the middle of the night, with the moon high and the ribbons of mist lit from within" hands back the dark version of the same landscape.
5. Change one field at a time. Swapping scene, light and color all at once gives you another image, not yours adjusted.
Tip: generate the bright version and the dark one and use one on each device. It is the same landscape, and it does not look like the same wallpaper twice.
