真实记忆收藏品海报设计

Transform the provided real photo into a premium editorial-style vertical poster (3:4 aspect ratio) that blends realistic photography with collectible object design aesthetics. COMPOSITION: Split the canvas horizontally into two equal 50% sections. BOTTOM HALF: Preserve the original photograph exactly as captured. Do not repaint, retouch, relight, stylize, crop, simplify, or alter any detail. Maintain full photographic realism, texture, lighting, shadows, atmosphere, and environmental complexity. TOP HALF: Replace with a minimalist negative-space composition inspired by modern gallery posters, Muji editorial layouts, and Xiaohongshu travel design aesthetics. BACKGROUND: Use a soft matte background derived from the dominant color palette of the original image. Avoid flat generic colors. The background should feel atmospheric and emotionally connected to the photo: subtle paper grain, soft gradient fog, faded pigment texture, delicate lighting falloff, premium tactile surface. SUBJECT EXTRACTION: From the original photo, extract ONLY the most emotionally recognizable visual signature of the scene. Do not simply copy the entire subject. Examples: - a distinctive rooftop silhouette - a window shape - a neon sign contour - a doorway arch - a food bowl outline - a mountain edge - a bicycle profile - a street lamp geometry - a human pose silhouette MEMORY OBJECT TRANSFORMATION: Transform the extracted element into a collectible miniature object suspended in space between reality and graphic design. The object should feel like: - a museum souvenir - a ceramic fridge magnet - an enamel city badge - a handcrafted acrylic charm - a curated design collectible STYLE: Minimal, iconic, emotionally distilled. VISUAL CHARACTERISTICS: - simplified geometry - preserved signature traits - soft rounded edges - subtle bevel depth - tactile material realism - delicate ambient shadow - thin off-white outline border - clean silhouette readability - tiny scale relative to canvas - generous surrounding whitespace PLACEMENT: Place the object slightly above center within the upper half. Do not make it large. The emptiness around it is important. AESTHETIC GOAL: The final image should feel like: "a real memory transformed into a collectible emotional artifact." Mood: quiet, curated, poetic, premium, contemporary, emotionally restrained. Avoid: over-design, clutter, typography, collage chaos, stickers, cartoon appearance, excessive detail, busy layouts, fake AI aesthetics. Visual references: Japanese editorial minimalism, boutique city branding, collectible souvenir design, contemporary exhibition posters, premium lifestyle magazine layouts, Xiaohongshu architectural memory aesthetics. Ultra refined composition, cinematic restraint, tactile realism, emotionally intelligent minimalism.
