Create a “minimalist geometric installation-style product poster” for the【subject product】. If I provide a product image, use it as the primary reference, preserving the product’s core appearance features, packaging form, colors, materials, brand identity and overall character, and prioritize the dominant colors and color relationships from the product image in the design. If I don’t provide a product image, automatically generate an appearance and packaging that fit the【subject product】’s positioning, and based on its attributes, category traits and character, naturally match a main color, auxiliary colors, prop shapes and display method. Overall poster style requirements: Use a high-key white or warm-white studio background, clean, translucent, soft and bright overall, with a premium commercial feel and modern brand visual character. The composition is not an ordinary e-commerce studio shot but a concept poster blending a brand visual proposal, artistic still-life photography and 3D product display. The main subject should include: 1. The【subject product】itself 2. The product packaging 3. Related raw materials, slices, components, functional elements or material details The three together form a complete visual chain so viewers immediately understand “what this product is, what its content is, and what the selling point or origin is.” Add simple, design-driven geometric installation props, for example: cylinders, cubes, long bars, rings, spheres, semicircles, platforms, stacked blocks, acrylic stands, toy-like structures, etc., to support, suspend, surround or set off the product, forming an artistic display composition full of order, rhythm and layering. The color scheme should unfold naturally around the product itself, with the product’s associated color as the visual core, paired with neutrals like white, cream and light gray, adding a small amount of accent color when needed, so the colors are unified, restrained, comfortable and fresh—not cluttered or gaudy. Different products should automatically adapt to different palettes; do not fix on a single background color. Material rendering should be delicate and realistic, with high-quality commercial rendering texture. Transparent plastic, acrylic, frosted materials, paper labels, glass, metal, smooth plastic, fruit-flesh texture, food textures or product surface details should all look natural and believable. Slight reflections and soft shadows are allowed, but not too heavy or messy. The composition requires ample white space, a clear subject, a balanced image and clean visuals, with a relaxed, gentle, modern, refined, approachable brand character with a touch of playfulness but not childishness. The overall feel should be like a highly aesthetic brand product KV poster, very suitable for e-commerce key visuals, social media recommendation images and product display images. Output requirements: - Vertical composition - Aspect ratio - Single poster - Strong sense of premium quality, simplicity and brand
