奢华品牌产品关键视觉，象牙白背景

[BRAND NAME] + [PRODUCT] Act as a Senior Luxury Fashion Art Director and Studio Photographer specializing in high-end product key visuals for flagship campaigns, e-commerce editorials, and mobile-first brand content. PHASE 1: FORMAT & CANVAS Vertical format, 9:16 aspect ratio. Canvas background: a single flat field of warm off-white - not pure white, not grey. Target tone: soft ivory cream (#F4EFE6 equivalent), uniform and completely shadowless across the entire background plane. Autonomously determine [BRAND NAME]'s signature background tone - if the brand has a recognized house color for its packaging, tissue paper, or lookbook backgrounds, shift the canvas toward that specific off-white or neutral. The result must feel like an official brand document, not a generic studio. PHASE 2: BACKGROUND PATTERN (WATERMARK LAYER) Autonomously identify [BRAND NAME]'s iconic surface pattern, monogram, or archival motif - examples: a house monogram, toile print, geometric logo repeat, heritage emblem, or signature textile pattern. Render this pattern across the entire background canvas as a ghost watermark: same tone as the background but with a slight value shift (approximately 8–12% darker or lighter than the base). The pattern must be large in scale - individual motifs spanning 15–25% of canvas width. Opacity: 10–18% maximum. No hard edges. The pattern should feel embossed or tone-on-tone woven, not printed. It must recede behind all other elements. PHASE 3: LOGO PLACEMENT Autonomously reproduce [BRAND NAME]'s official logo with complete fidelity - correct letterforms, proportions, secondary marks (emblems, crowns, stars, monogram icons). Place the logo centered horizontally in the upper third of the frame (top 30% of canvas). Scale: the logo should span approximately 40–50% of canvas width - prominent but not overwhelming. Logo rendering: flat 2D, no extrusion, no chrome. Color: autonomously apply [BRAND NAME]'s official logo colorway - the exact brand-standard color(s) used on official packaging and website. If the brand uses a two-tone logo (icon + wordmark in different colors), preserve that hierarchy precisely. Directly below the main logo mark, place the full [BRAND NAME] wordmark in spaced capital letters - clean, geometric sans-serif, tracking: +200 to +300, same brand color, optical size approximately 60% of logo height. No decorative elements between logo and wordmark. PHASE 4: PRODUCT PLACEMENT Render [PRODUCT] as a photorealistic studio object with maximum material fidelity: - Leather: visible grain, pore structure, stitching thread texture, realistic edge paint. - Hardware: gold or silver metal with micro-reflections, not flat. - Canvas/fabric: woven fiber detail, not smooth CG. - All brand-specific surface patterns on the product must be accurate and legible. Placement: the product enters the frame from the bottom-right corner at a natural 25–35 degree angle, as if casually placed or mid-motion. The product is cropped - only 60–75% of the object is visible within the frame. The crop should feel intentional and editorial, not accidental. The product occupies the lower 55–65% of the canvas. The product must feel physically present in the space - not floating. Cast an extremely soft, barely visible contact shadow (opacity 8–12%) on the canvas beneath the nearest edge. No hard drop shadows. PHASE 5: LIGHTING Lighting: simulated large north-facing studio window light. Soft, directional, shadowless on the background. Color temperature: 5500–6000K (neutral daylight, slightly cool). Key light: large softbox equivalent from upper-left, filling the entire product surface evenly with minimal contrast ratio (1.2:1 to 1.5:1 max). Fill light: large bounce from right side, eliminating all harsh shadows. No rim light. No dramatic contrast. The lighting philosophy is: "the product sells itself - light only reveals, never performs." Global Illumination enabled for subtle inter-reflections between product surfaces. No specular hotspots on leather - only on metal hardware. PHASE 6: TYPOGRAPHY & FINISHING Bottom of frame: a thin horizontal rule line (1px, brand color, 80% canvas width, centered). Below the rule: a single line of micro-copy - a social handle, collection name, or campaign label - in the same clean sans-serif, lowercase or small-caps, minimal tracking. Autonomously generate a contextually appropriate label for [BRAND NAME]. TECH SPECS Render engine: photorealistic CGI, Keyshot / Octane product visualization aesthetic. Resolution: 9:16, ultra-high detail. Depth of Field: f/16 equivalent - everything in sharp focus. Zero bokeh. Tack-sharp edges on all product details.Tone mapping: clean, true-to-life. No filmic crush. No vignette. No grain. Color grade: neutral, faithful to real product color. Slight warmth in the ivory background only. No AI-plastic normals on leather or fabric. Microscopic surface imperfection maps required. No reflections on background. No environmental reflections - studio only. Mood reference: Louis Vuitton / Bottega Veneta / Celine official e-commerce and campaign photography standard. Clean enough to be used as a press image.
