Prompt
Composed for a 9:16 vertical wallpaper, create a subtle red gel-lit fog column drifting upward through near-black, with a clear vertical flow. Anchor the densest fog texture in the lower-middle, then taper into finer wisps as it rises, leaving the upper third calmer and darker. Keep the fog soft and volumetric, never thick or cloudy.
Use controlled cinematic lighting: a soft red side key reveals depth, with gentle rim separation along a few wisps and deep charcoal shadows inside the volume. Add a whisper of grain and extremely sparse particulate sparkle to suggest real atmosphere without clutter. Keep bloom restrained so the gradient stays smooth and OLED-friendly.
Reserve a clean negative-space zone in the upper half where the fog thins into near-black. Keep the composition minimal and unmarked, with no distinct silhouettes or readable shapes. The result should feel like premium abstract lighting design, calm but alive.
