Conversion d'affiches haut de gamme minimalistes à partir de photos

Please convert each photo I upload into an independent minimalist high-end design poster, without multi-collage; each photo must be generated separately. Adopt an overall vertical 3:4 composition, with two upper and lower zones strictly 1:1 in height, each occupying 50% of the canvas. The upper half preserves the original photo, maintaining the main structure, real texture, natural light and shadow, and original color atmosphere; only apply a subtle photographic adjustment to give it an artistic photography and morning art exhibition feel. To fit the format, naturally expand the sky, ground, or ambient background, but do not stretch, distort, or alter the main subject. The lower half extracts the most recognizable outline and structure of the subject from the photo, using simple geometric shapes, flat color blocks, fine line strokes, and white space for a minimalist vectorized expression. Do not use realistic illustrations, do not add complex details, but retain the main characteristics of the subject so the original can be recognized at a glance. The color palette is extracted from the upper image, and a few horizontal lines, vertical lines, or circular abstract elements may be added. Overall, use a beige or light background with ample white space; the main subject centered, with a balanced and restrained composition. You may add a simple English title, style references such as international design works, architecture posters, art exhibition posters, and luxury visual systems, with a high-end, modern, elegant, artistic style; avoid common filter effects, cheap low-quality feel, cartoon style, electronic effects, and template feel.
