Conceptual Silhouette Void Style Prompt

Create a portrait-oriented 3:4 image, style named 【CONCEPTUAL SILHOUETTE VOID｜概念留白剪影风】. Suitable for people, animals, plants, architecture, cities, vehicles, food, objects, interiors, nature and travel photos, not limited to "travel" or any single scene. Upper half: retain 42%–48% of the input photo itself: ensure main subject, quantity, pose, perspective, spatial relationships, light, material and recognizable colors are preserved, only natural cropping, no overpainting, no scene changes, no adding/removing key subjects. Leave dry warm white margins between upper and lower parts, no borders, photo labels or original/AI watermarks. Lower half: do not copy the entire photo, nor draw the entire illustration. First extract one most meaningful semantic relationship, movement, contour or material rhythm from the original photo: e.g. a person's stance, an animal's body line, a flower's bloom, a branch's spread, a road's curve, a building's elevation, a vehicle's speed direction, a circle's circular relationship, a window's repetition rhythm, a mountain's rise or water's ripples. Choose only one subject, reconstruct it into a charcoal black, ink black or dark ink silhouette line drawing, with contour, flat fill or single-line gesture. The silhouette must trace back to the real subject in the upper half, but allow stretching, shrinking, skewing, rotating, cropping or leaving blank. Lower half: keep 60%–80% continuous warm white negative space, surface only extremely sparse texture and highlight particles. The silhouette edges may have subtle halos, dry brush particles or uneven ink density, but overall must be restrained, flat, dry, not blur into wash, nor become fine line drawing. People and animals may compress into faceless, clothes-ignored whole silhouettes; architecture, plants, food and objects only keep the minimal structure that identifies the form, do not restore photo details. At most use one or two extremely fine auxiliary lines to hint direction, do not add secondary silhouette objects. Silhouette form in charcoal black, ink black or dark ink only, at most extract one extremely subtle accent color from the original image, color varies with photo, not fixed to blue, green or city palette. Lower half may add one line very small, precise English caption describing the semantics, e.g. ONE GESTURE / OPEN SPACE, ARC / STILLNESS or SINGLE FORM; do not add big titles, long paragraphs or fake location info. Overall should let the upper half carry the photography essence, the lower half carry the single concept, form judgment and blank rhythm. Forbid full-scene repetition, multiple overlapping objects, continuous route line nodes, full city skyline template, photo frames, full-page wash, color poster, heavy line art, 3D rendering, auto-tracing, Logo, watermark, fake text, AI watermarks and original watermarks.
