Erweiterte Design-Postererstellung aus Fotos

Create each uploaded photo as an independent, high-end design poster - no multi-image collages, each photo output separately. Overall use a 3:4 vertical composition, with the upper and lower sections at a 1:1 height ratio, each occupying 50% of the frame. The upper section retains the original photo, preserving the subject's structure, authentic texture, natural light and shadow, and original color atmosphere - only applying light high-end photographic color grading to give it the quality of art magazines, independent publications, and exhibition photography. To fit the frame, the sky, ground, or environmental background may be naturally extended, but the subject must not be stretched, distorted, or altered. The lower section extracts the most recognizable **subject, silhouette, posture, and narrative relationships** from the photo, reconstructing them into a linear experimental poster with geometric order. The subject is formed by the aggregation of high-density repeated lines, offset hatching, rapid loops, and slight jitter trajectories, retaining clear recognizable edges while keeping the interior unstable and fluid; the periphery uses homologous but thinner, sparser, lighter lines spreading outward, establishing rational structure through horizontal, vertical, diagonal, arc, tangent, or implicit grid lines - creating a visual tension of **high density at the center, low density at the periphery, with geometric order coexisting with free linearity**. The color palette is extracted from the upper photo, selecting the **most vital, most recognizable, and most representative color of the subject's spirit** as the primary line color - not averaged by area, and not deliberately aged or grayed; it may be moderately purified, brightened, and corrected to make the color cleaner, more vivid, and more modern. The overall approach uses a light background, a single primary line color, and black/gray micro-typography, building hierarchy through line density, weight, and overlapping - avoiding muddy colors, gray haze, fixed palettes, multi-color mixing, and digital gradients. Text intervenes cleverly as part of the composition, extracting an extremely short English title from the photo's emotion, action, time, state, or metaphor, paired with minimal numbering, fitting philosophical quotes, state words, scales, or micro-annotations. Text may align along geometric axes, subject contours, or line-field boundaries - horizontal, vertical, rotated, interleaved, or offset - using ultra-small type sizes, light weights, wide letter-spacing, and precise alignment to create a high-end editorial feel, where rational typography anchors the restlessness of free lines. The overall composition maintains generous negative space, a single visual focal point, and clear geometric order, presenting a **clean, restrained, sharp, experimental, artistic, and vital** visual character. Avoid random doodles, directionless line clusters, dirty vintage aesthetics, cyber-tech vibes, commercial promotional feel, cartoonishness, and template-like results.
