Schwarz-Weiß-Editorial-Poster mit Farbakzent

Create one independent high-end design poster from each uploaded photo, no multi-image stitching, each photo output separately. Overall use a 3:4 vertical composition, with the upper and lower areas strictly 1:1 in height, each occupying 50% of the frame. The upper half retains the original photo, preserving the main structure, authentic texture, natural light and shadow, and original color atmosphere, with only subtle high-end photographic color grading to give it the quality of an art magazine, independent publication, and exhibition photography. To fit the aspect ratio, the 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, posture, and narrative relationships from the photo, reconstructed as a minimalist black-and-white hand-drawn editorial illustration. Use a horizontal or vertical solid black rectangular color field as the primary visual stage, with most of the subject existing inside the rectangle, while selecting the most recognizable head, top contour, branches, roof, limbs, object edges, or other key structures to naturally break through the rectangle boundary, forming a clear "crossing-over" relationship. The subject is not pasted onto the black rectangle, but appears to emerge, pass through, or grow out of the black space, making the rectangle both background and part of the composition. The subject retains only the most necessary outer contour, posture, and key structures, rendered with smooth black hand-drawn lines + white negative space + a small amount of gray tonal areas. Lines should be concise, smooth, stable, with natural hand-drawn elasticity and rhythm, allowing slight handcrafted feel, but without excessive trembling, repeated strokes, rough noise, or deliberate childishness; overall closer to a clean illustrator linework rather than rough casual doodling. Internal details remain extremely minimal, using only a few structural lines, expression lines, and local shading to establish recognizability. Overall dominated by black, white, and gray, but one core local accent color may be added when necessary as a finishing touch. This color can only fall on the most critical, narrative, or memorable local detail, such as a part of the subject, a small object, a key surface, a focal action point, or an emotional signal. The accent color area must be very small, precisely placed, and clearly purposeful, like the only illuminated spot in the frame, used to enhance memorability and emotional tension, not to break the overall black-and-white order. The color should be extracted from the original image as the most representative single highlight color, moderately purified. The composition emphasizes the conflict between the geometric order of the black rectangle and the free contour of the subject. The rectangle serves as a stable, heavy visual base, while the subject creates vitality through asymmetric placement, partial cropping, and boundary crossing; large areas of white paper negative space surround the black area, forming a strong yet restrained relationship of black, white, and gray. Auxiliary structures may be transformed into very few straight lines, sloped planes, platforms, edges, or geometric slices, but must not form a second subject. Typography establishes a lightweight black-and-white editorial micro-layout system, extracting a short English title from the photo's action, mood, state, or metaphor, paired with 1-3 groups of minimal annotations, numbers, status words, or short phrases. Text may sit close to the black rectangle edge, hide in negative space, align with the crossing direction, or create alignment and misalignment with the subject contour; use black handwritten type, thin sans-serif, or restrained serif fonts, keeping small scale, so the text feels like an illustrator's signature and editorial mark rather than a commercial headline. Overall visual character: pure white paper surface × black geometric color field × fluid hand-drawn lines × subject crossing boundaries × single-point color accent, restrained, intelligent, light, witty, modern, and with an art-publishing feel. Avoid color cartoon, complex scenes, smooth vector outlines, realistic shading, 3D texture, pure black silhouettes, rough scribbles, and template-style centered layouts.
