Examples


Fantasy scene

Visual concept
Ultra-high-fashion editorial beauty portrait of a fair-skinned female model with sleek center-parted hair tightly pulled into a low bun, wearing a fitted black ribbed turtleneck sweater. Dramatic studio lighting creates a bold diagonal shadow slicing across the face, emphasizing facial structure, freckles, and glossy deep-red lips. Minimal makeup with natural skin texture, cinematic contrast, rich warm color palette. Background consists of striking geometric color-blocked panels in vibrant orange and deep burgundy red, forming strong diagonal lines. Clean composition, luxury magazine cover aesthetic, contemporary fashion campaign, fine-art portrait photography, sharp focus, ultra-detailed skin, professional studio setup, high dynamic range, moody atmosphere, Vogue-style editorial, medium close-up framing, 85mm lens, f/2.8, photorealistic, 8K quality. Negative Prompt: blurry, low resolution, overexposed highlights, flat lighting, messy hair, smiling expression, heavy accessories, jewelry, cluttered background, text, watermark, logo, extra limbs, distorted face, cartoon, illustration, CGI, oversaturated skin, unnatural anatomy, poor composition, noise, motion blur.

Fantasy scene

Visual concept
Ultra-realistic design culture magazine cover featuring a creative Korean woman in a bold yellow structured blazer and black wide-leg trousers — matching the product's colorway — holding a Teenage Engineering OP-1 Field synthesizer horizontally with both hands, fingers hovering over the tiny keys mid-composition, deep in creative flow. Bold graphic makeup, sharp geometric liner, yellow eyeshadow accent. Sleek straight bob. Background: clean white Bauhaus-inspired studio with bold yellow color block wall panels, ultra-graphic composition. "DEZEEN" masthead in precise sans-serif with "INSTRUMENTS OF DESIGN ISSUE" callout. 50mm lens, ultra-detailed OP-1 tiny key and OLED display, 8K photorealistic design editorial. Negative: cartoon, blurry, incorrect product shape, watermark, distorted.

Visual concept
Use the provided image strictly as the reference for the subject’s face, age, and identity. Lock facial identity with the highest priority. Preserve the exact facial structure, proportions, skin tone, jawline, eyes, nose, lips, and overall likeness. Do not beautify, stylise, feminise beyond the natural identity, or alter facial features in any way. Create a modern, high-end studio portrait of a woman in a vertical 4:5 aspect ratio. Full-body seated editorial composition, centre-framed with balanced negative space. The overall visual aesthetic should feel clean, luxurious, powerful, and magazine-quality. The subject is wearing a sharply tailored deep forest green women’s suit with a refined structured blazer and tailored straight-leg trousers, paired with a crisp black fitted button-down shirt, elegant black leather formal heels, and a black wristwatch. The overall color palette is rich deep forest green (#225d57) with a polished luxury editorial aesthetic. The subject is seated in a sleek modern white molded plastic chair with four thin metal legs. Her posture is relaxed and confident, leaning back comfortably with her back supported by the chair rather than sitting rigidly upright. Torso angled slightly toward the viewer’s left side. Head turned left, showing a refined three-quarter profile. Gaze directed toward the left side of the frame, not toward the camera, creating a thoughtful editorial look. Body language: Shoulders relaxed and naturally dropped. Right hand resting near the upper thigh, fingers relaxed and naturally extended. Left elbow resting lightly on the edge of the seat, with the wristwatch visible. Legs extended forward in a relaxed seated stance. Both feet resting naturally on the floor, slightly apart and angled toward the left side of the frame. The pose should feel elegant, grounded, natural, and editorial — never stiff. The chair is placed in a seamless dark green studio environment where the floor and background blend smoothly. Behind the subject’s head and upper torso is a medium-sized glowing white circular LED ring light, centered like a modern halo. This creates a strong graphic visual element and subtle rim-light separation from the background. Use cinematic studio lighting: soft key light from the left side shaping the face, gentle shadow retention for depth, and subtle controlled fill light to preserve detail. The LED ring behind the subject should glow clean and bright without overpowering the subject. The lighting mood should feel dramatic, premium, and polished. Photorealistic, ultra-detailed, premium commercial portrait, sharp focus on facial features, suit texture, shoes, chair surface, and lighting contrast, refined editorial color grading, clean studio finish, no bad anatomy or bad proportions, no distortion, no exaggerated limbs or hands.
