Identity and reference
Use the uploaded photo as the primary face and character reference. Keep the person’s identity 100% identical to the photo: same facial features, bone structure, skin tone range, gender, perceived age, hairstyle shape, hair length, hair volume, hair color and overall facial proportions. Do not change the person’s gender or make the face look younger or older. Preserve the exact facial expression, nose, eyes, lips, jawline, and any unique marks such as moles, freckles, scars, or skin texture. All metallic transformations must strictly follow the same underlying face structure, replacing surface areas but never reshaping or redesigning the face.
Positive prompt (with rusty metal + gold)
Ultra‑realistic cinematic portrait of this man, using the uploaded image as the exact facial reference, where parts of his face are transformed into metal: a complex mosaic of corroded rusty steel and bright polished gold seamlessly integrated into his real skin. Sections of his cheeks, forehead, jawline and temples are replaced with rough, oxidized metal plates: rusted iron and steel with flaking paint, pitted surfaces, orange‑brown corrosion, and deep scratches that follow his natural facial planes. Other regions, such as portions of the brow, cheekbones and jaw edges, are in sharp contrast, made of smooth, mirror‑polished gold plates and inlays, with crisp bevels and sharp reflections, giving a luxury, almost sacred mechanical feel. The metal and gold segments are fitted together like mechanical patches and armor pieces, revealing subtle seams where skin meets metal, but always matching his true bone structure underneath. His expression is calm yet powerful, eyes intense and focused, reflecting both the warm glow of gold and the roughness of rust. Background: deep charcoal gradient with a faint industrial haze, minimal and elegant, pushing all attention to the hybrid face. Ultra‑HD, 8K‑level detail, luxury cinematic grading, high contrast, crisp focus on the eyes and metallic areas, editorial fashion portrait style with a dark, art‑house sci‑fi atmosphere.
Lighting
Dramatic Rembrandt lighting from one side, with a characteristic light triangle on the shadowed cheek.
Soft but directional key light emphasizing the contrast between rough rusty textures and glossy gold reflections.
Controlled specular highlights on gold areas, producing rich, warm glows and clear highlight shapes.
Subtle, softer reflections on the rusty metal, revealing texture and depth without flattening details.
Gentle rim light separating head and shoulders from the dark background, adding a cinematic outline.
Camera and lens
Camera style: cinematic portrait / editorial photography.
Lens: 85 mm portrait lens look with shallow depth of field, face in sharp focus, background smoothly blurred.
Framing: tight head‑and‑shoulders composition, slightly off‑center for a dynamic, magazine‑cover feel.
Focus: pin‑sharp on the eyes and closest metal/gold regions, gradual falloff toward ears and background.
Style and detail
Rusty metal: highly detailed corrosion, flaking layers, tiny holes, pitting, stains, subtle streaks of rust running with gravity, color variation from deep brown to orange.
Gold: smooth, reflective, warm‑toned gold surfaces with fine scratches, crisp edges, and bright specular highlights; subtle imperfections to keep it realistic, not plastic.
Skin: visible pores and natural texture where still visible, showing clear transitions from organic skin to metal and gold segments.
Micro‑details: small screws, rivets or weld lines holding certain plates in place, delicate engraving lines on some of the gold parts, realistic imperfections everywhere.
Overall vibe: dark, luxurious, post‑apocalyptic meets high fashion, ultra‑real, no cartoon exaggeration.
Negative prompt
Do not change the man’s identity, gender, perceived age, or core facial proportions from the reference photo.
No full robotic or cyborg redesign that replaces the entire head; keep a clear mixture of human skin, rusty metal and gold.
No anime, cartoon, comic‑book or painterly style; no flat illustration; no toon shading.
No chrome‑only or overly shiny sci‑fi armor; specifically keep rough rusty metal and warm gold, not neon or plastic.
No busy background, no text, logos, buildings or props; no futuristic city; keep the simple dark gradient background.
No distorted anatomy, no extra eyes, no warped features, no low resolution, no noisy or blurry image.
