A 3:4 vertical premium design poster. Each uploaded photo should be created as an individual finished piece, with no multi-image collage or photo splicing. The upper and lower sections of the image must be strictly divided 1:1, each occupying 50% of the canvas. The upper half should preserve the original photo, maintaining the subject’s identity, structure, pose, realistic texture, natural lighting, and original color atmosphere. Apply only subtle high-end color grading to achieve the visual quality of an art magazine and exhibition image. The composition may naturally extend the surrounding environment to adapt to the aspect ratio, but do not stretch, distort, or alter the subject. The lower half should extract the most recognizable subject features, contours, structures, poses, and narrative relationships, reconstructing them into a block-based, modular geometric deconstruction illustration. Do not fully replicate or realistically trace the original image. Remove irrelevant details and retain only the visual memory points that best represent the identity and character. Rebuild the image through geometric simplification, layered shapes, and collage-like reconstruction, allowing the viewer to immediately associate it with the photo above. The design should emphasize a strong sense of blocks, modularity, geometric segmentation, and large complete shapes. Avoid excessive fragmentation or dividing the image into many scattered small pieces. Instead, organize the subject using fewer, larger, and more complete rectangles, squares, rounded squares, ellipses, triangles, and irregular geometric blocks. For portraits, use square-shaped facial structures, clear jawlines, and geometric facial features. For architecture, transform it into overall block volumes, facade divisions, window rhythms, and structural transitions. Animals, plants, objects, and landscapes should also be refined into geometric forms with a block-based order. Moderate exaggeration is allowed, but the result must remain mature, restrained, simple, and elegant. Avoid overly detailed, childish, or scattered collage effects. Use a combination of flat color blocks, collage composition, and modernist geometric language. Color areas should feel like paper pieces assembled together, creating a clear and organized cut-paper collage effect. Remove complex backgrounds and retain only a few necessary shapes, avoiding the creation of a secondary visual focus. The composition should maintain a small-scale subject with large areas of negative space. Arrange elements freely according to the subject’s direction, proportion, visual center of gravity, and structural flow. The composition may be asymmetrical, edge-aligned, or partially cropped, with clear hierarchy, balanced density, and emphasis on positive and negative space, visual weight of blocks, and breathing room. The material texture should feature gentle paper grain and a subtle printmaking feel. Preserve delicate paper texture, soft noise, and slight printing characteristics within the color blocks, resembling handmade paper collage or fine art printing. Avoid smooth vector graphics, 3D rendering, photo filters, and excessive retouching. Extract 2–4 of the most recognizable colors from the upper photo that best represent its mood and character, then refine them into a more sophisticated color system. Colors may be brightened, purified, and desaturated appropriately, transforming them into elegant modern tones such as cream white, apricot, peach pink, coral orange, mist blue, sage green, warm brown, and soft purple. The main colors should be vivid but not harsh. Secondary colors should be gentle and layered. The overall mood should feel clean, warm, fashionable, approachable, and refined. Avoid muddy yellow, dirty gray, dark brown, fluorescent colors, cheap candy-like palettes, and chaotic color combinations. Text may be introduced in small amounts. It can be a short title, note, number, or description related to the subject’s identity, location, emotion, or symbolism. Text should remain small, light, and restrained, placed within negative space or corners, forming a refined relationship with the graphics. Do not create commercial-style headline-heavy typography. The overall design language should be unified through large geometric blocks, restrained collage, sophisticated soft color palettes, paper texture, generous negative space, and editorial-style layout. Regardless of whether the subject is a person, building, animal, plant, object, or landscape, maintain clear identity and modular geometric order. Avoid realistic reproduction, excessive fragmentation, childish collage, complex perspective, overly dense details, cartoon style, 3D appearance, template poster aesthetics, and cheap cultural merchandise style. Do not change the original image. The generated image should preserve the original photo’s core characteristics, and avoid adding unnecessary or irrelevant text elements.
