Prompt
black sand beach at dusk shot as a long-exposure photograph, silky white wave foam sweeping in soft veils across dark volcanic sand, smooth misty water blur, distant sea stacks as faint charcoal silhouettes, deep slate-grey sky with no visible sun, dark minimal seascape with the brightest foam confined to the lower third of the ultrawide frame

How to use this prompt
"Long-exposure photograph" is the phrase that converts crashing surf into the silky white veils this wallpaper depends on — describe waves without it and Flux freezes sharp foam that reads as visual noise behind icons. "Brightest foam confined to the lower third" keeps the upper two thirds of the 21:9 strip in dark sand and sky, so desktop icons and menu bars sit on near-black. Keep cfg at 3.5; pushing guidance higher makes the water blur plasticky and kills the photographic grain. If the sea stacks render too prominent, demote them: "barely visible sea stacks dissolving into haze" pushes them back a depth plane.
Variations to try
- Moonlit version — add "low full moon behind thin cloud, one soft silver reflection lane on the wet sand" for a single focal accent off-center
- Phone version — rerun at 9:16 with "one wave veil curving through the bottom quarter, empty dark sand rising to the top" so the clock sits on black
