Foto in künstlerisches Poster mit Schwarz-Weiß-Kreideillustration verwandeln

I will create one independent, high-end design poster for each photo you upload, with no multi-image collages - each photo is output separately. The overall format is a 3:4 vertical composition, with the upper and lower zones strictly 1:1 in height, each occupying 50% of the frame. The upper half retains the original photo, preserving the subject's identity, structure, pose, authentic texture, natural light and shadow, and original color atmosphere - only applying light, high-end photographic color grading to give it the feel of an art magazine, independent publication, or exhibition photograph. To fit the format, the sky, ground, or environmental background may be naturally extended, but the subject must not be stretched, distorted, or altered. The lower half extracts the most recognizable subject, silhouette, pose, and narrative relationships from the photo, reimagined as a minimalist, bold, dry-media silhouette illustration. Do not mechanically trace photo details; instead, compress the subject into rounded, sturdy, slightly naive generalized forms. The head, main contours, or the most memorable parts may be moderately enlarged so that the original remains instantly identifiable with minimal information. If the photo contains multiple subjects, preserve the most important interaction and treat them as a single visual unit rather than spreading focus evenly. The lower half uses only a near-pure white paper background plus dense black crayon, charcoal, or dry-brush marks - no color, no grayscale gradients. The black forms are not smooth solid vector blocks but are built from short, forceful repeated crayon strokes, retaining paper grain, broken lines, pressure marks, rough edges, uneven density, and areas of exposed white. Outlines are slightly wobbly, incomplete, and imprecise, keeping the image genuinely hand-made. The subject's most critical identifying features may be reinforced through "sudden white feature zones cut out of the black silhouette" - such as a face, eye area, window opening, vessel mouth, animal face, core structure of an object, or the most distinctive part. Then use minimal black dots, short lines, or symbols to complete expression and detail. Do not aim for realistic facial features or precise structure; instead, create a direct, playful, and strong recognition relationship between black and white. The composition maintains large areas of pure negative space plus one primary visual relationship. The subject may float centered, be slightly offset, partially cropped, or placed near the lower edge, with only a rough ground friction line, a few short strokes, or minimal environmental symbols suggesting space. Grass blades, raindrops, smoke, tabletops, shadows, roads, wind, or other environmental information should be compressed into very few crayon marks, keeping the background quiet and open. The overall goal is not a complex scene but a single gesture, action, distance, or relationship carrying the main narrative. Text retains a small typographic system that balances high-end editorial and children's book sensibilities. Do not just write a place or object name; instead, distill a short English title from the photo's mood, action, relationship, time, or tiny story, paired with a number, a fitting quote, a chapter number, or one very short understated caption. Text may be restrained printed small type, or include a very small amount of clumsy handwriting, crayon lettering, or imperfect glyphs, as if it naturally belongs to the illustration. Text must interact cleverly with the graphics: it can sit along the ground line, extend along the subject's movement direction, hide in large negative space, slightly overlap the silhouette, fit into the negative space between two subjects, or be connected to the subject by a thin line with a number. Keep it to "one short title + 1-2 groups of tiny auxiliary text" - text becomes part of the compositional rhythm, not a typical poster headline. The overall look is bold black, clean white, simplified forms, and rough texture, balancing childlike warmth, softness, quietness, humor, and loneliness - like an old black-and-white children's book re-edited by a high-end design studio. Avoid smooth digital outlines, precise linework, realistic shading, heavy impasto, 3D effects, color, large gray washes, cartoon sticker feel, and templated commercial illustration.
