Porte-clés en acrylique premium, photo produit en CGI

[BRAND NAME] Act as a High-End CGI Product Photographer and 3D Render Artist specializing in streetwear merch and limited-edition collectibles. PHASE 1: CONCEPT & OBJECT Create a photorealistic CGI product shot of a premium keychain set suspended in mid-air against a neutral gradient studio background. The keychain set consists of THREE elements connected to a single polished silver carabiner clip with a gold-plated split ring: ELEMENT 1 — ACRYLIC TAG: A rectangular acrylic charm (approx. 4:9 ratio, rounded corners, 3mm thick). Layered construction: clear gloss acrylic front panel over a [BRAND NAME]-colored background insert. The background insert carries bold, condensed all-caps typography — autonomously generate a short poetic or brand-relevant phrase (4–8 words) that matches [BRAND NAME]'s tone of voice, set in a heavy condensed grotesque typeface (Bebas Neue / Impact / custom bold). Include [BRAND NAME]'s URL or tagline in small print at the bottom of the insert. Micro-printed fine text fills the lower third as a design texture element. ELEMENT 2 — OVAL MEDALLION CHARM: A die-cut oval hoop/ring shape (donut silhouette, 40mm diameter) made from tinted translucent acrylic or resin. Autonomously determine the iconic brand color of [BRAND NAME] and apply it as the tint (deep saturated, jewel-tone translucency — e.g., gold, cobalt, emerald, crimson). The [BRAND NAME] wordmark is engraved or UV-printed in bold all-caps along the inner curve of the ring. Add 1–2 small iconographic symbols (logo mark, globe icon, cloud glyph) laser-engraved onto the face. Subtle radial sun-ray pattern embossed on the surface. ELEMENT 3 — HARDWARE: Silver anodized aluminum carabiner with knurled locking barrel. Gold-plated brass split ring (key ring loop) at the top. All metal surfaces show micro-scratches and machining marks — no perfect CGI plastic. Industrial precision aesthetic. PHASE 2: MATERIAL & TEXTURE Render all acrylic elements with full Ray Tracing and Subsurface Scattering — light must visibly pass through the tinted acrylic creating internal glow. Apply Fresnel reflection on acrylic edges. Surface imperfections: hairline scratches, micro-dust particles, smudge traces on the clear panel (subtle, editorial-level — not dirty). Metal: PBR metallic workflow — anisotropic specular highlights on the carabiner barrel, brushed finish on the ring. Typography on acrylic must appear screen-printed or UV spot-coated — slight ink texture, not floating. PHASE 3: COMPOSITION & STAGING Levitation shot: the entire keychain set hangs suspended from the top of frame, centered with a 10–15 degree rotation to the right (showing dimensionality). Nothing touches a surface — pure float. Camera angle: slightly below eye-level looking up at ~5 degrees, portrait orientation (4:5 ratio). Depth of Field: focus plane centered on the oval medallion, acrylic tag in sharp secondary focus, top hardware with micro bokeh blur. Aperture equivalent: f/4.0. Negative space: generous — object occupies 55% of frame. PHASE 4: LIGHTING Primary: large octabox soft key light, positioned top-right at 45 degrees — creates clean specular bloom on acrylic edges. Secondary: subtle rim light from bottom-left, cool temperature (5500K), separates the object from background. Background: seamless gradient cyclorama — dark steel blue (#1a2535) at top transitioning to pale silver-grey (#d0d8e0) at bottom. No hard shadows cast. Global Illumination active. Chromatic Aberration: micro-level, visible only on acrylic edges (adds realism, prevents CGI-plastic look). No lens flare. No neon. No HDR overblown highlights. TECH SPECS Render engine: Octane Render or Blender Cycles (path-traced) Resolution: 4096 x 5120px (4:5 portrait) Samples: 4096 minimum Color profile: Adobe RGB, D65 white point Post-processing: subtle film grain overlay (ISO 400 equivalent), +5 clarity, -10 highlights, neutral color grade Output mood: High-end streetwear lookbook / limited drop product page Style references: Kith accessories, Highsnobiety product editorial, Fragment Design merch photography NEGATIVE: No white studio infinity cove. No flat lay. No hand holding the product. No fake bokeh blur filters. No AI plastic sheen. No floating text outside the object.
