Visual concept

Use ONLY the facial identity from the uploaded reference image. Preserve the face exactly. Match hairstyle, hair color, hair texture, and bangs from the uploaded reference image. Ultra-realistic DSLR fashion portrait, beautiful young woman, standing in a graceful side profile with her body facing left while her face remains naturally visible, chin gently resting on the back of her hand, relaxed posture, elegant slim body, long layered beige trench coat over a black top, pleated plaid midi skirt, black gloves, luxury handbag, delicate earrings, wristwatch, calm thoughtful expression, soft feminine emotion, refined fashion editorial, minimal clean background, warm natural soft light, realistic skin texture, shallow depth of field, 85mm lens, f/1.8, ultra detailed, masterpiece, photorealistic, 8k. negative: low quality, worst quality, blurry, cartoon, anime, illustration, painting, CGI, 3D, doll, fake skin, deformed body, bad anatomy, bad hands, extra fingers, missing fingers, fused fingers, duplicate body, multiple people, cropped face, out of frame, closed eyes, exaggerated expression, muscular body, child, old woman, fat body, watermark, logo, text, signature, oversaturated, noisy, overexposed, underexposed

Visual concept

Create a vertical high-resolution experimental fashion editorial poster. 【Theme】: [Your Theme] 【Brand name】: [Your Brand Name] 【Collection title】: [Collection Title] 【Fashion / product direction】: [Fashion Product Direction] 【Main color palette】: [Main Color Palette] 【Model direction】: [Model Direction] 【Editorial copy】: [Editorial Copy] The image should feel like a high-end, cold, minimal and experimental fashion magazine poster. Use a large pale grey-white negative-space background with subtle paper grain, low-contrast noise and printed editorial texture. Avoid clean plastic white backgrounds or commercial studio backdrops. The main subject is [Model Direction], shown in a full-body or nearly full-body pose, placed slightly right of center. The pose should feel quiet, restrained, distant and editorial. The model should have a calm expression and high-fashion presence. Avoid influencer posing, exaggerated performance or commercial catalog energy. The clothing or product must have strong design value, clear silhouette and rich material details: sheer fabric, crinkled texture, soft volume, leather reflection, knit texture, structured tailoring, transparent layers, natural folds or subtle shine. Keep the person realistic, with natural skin texture and no plastic AI face. Add a controlled “ghost scan blur” effect: vertical motion trails, translucent afterimages, stretched scan lines, slight glitch displacement and soft dissolving blur around the left side of the body, lower garment edges, arms, shoes or product edges. The effect should look like the person, garment or product has been optically scanned, folded by paper texture, or dragged by memory. Important: keep the face or upper body relatively clear as the visual anchor. Do not blur the entire person. The key contrast is: clear emotional anchor + blurred ghost trace around the edges. If the theme includes a product such as perfume, jewelry, bags or shoes, place it subtly near the model, at the bottom of the poster or in the foreground. Connect the product with the model through reflection, transparent blur, liquid trace, glass distortion or scan-like afterimages. Do not make it look like a normal e-commerce product image. Use a minimal fashion magazine layout: small English title at the top, such as “[Brand Name] / [Collection Title]”; a small paragraph of editorial copy near the body or product; and a tiny abstract logo at the bottom. Typography should be clean, restrained, small, high-end and sans-serif. Avoid large promotional text, loud fonts or ad-like design. Overall mood: low saturation, low contrast, cold, quiet, premium, experimental, editorial, archive-like, independent designer lookbook, avant-garde fashion magazine, artistic brand campaign. Avoid: cartoon, illustration, cheap poster design, e-commerce ad, promotional banner, large text, complex background, multiple random people, collage grid, over-sharpening, over-retouched skin, obvious AI look.

Visual concept

Ultra-realistic luxury product advertising campaign, a futuristic white architectural room with tall geometric walls and a glossy black-and-white checkered reflective floor. A giant premium over-ear headphone in the foreground (black matte body with deep burgundy ear cushions), positioned as the hero product using forced perspective. Behind it, a stylish young male fashion model wearing black sunglasses, a cream bomber jacket, beige shorts, and white sneakers crouches dynamically, reaching one hand toward the camera with exaggerated perspective. Clean luxury lighting, soft volumetric glow, floating dust particles, subtle audio waveform graphics in the background, minimal premium aesthetic, editorial fashion photography, commercial product render, ultra-sharp details, cinematic composition, depth of field, 8K, Octane Render, photorealistic. Leave space at the top for branding and the headline "Hear Your Style" in elegant modern typography. Prompt 2 – Perfume Advertisement: Luxury perfume commercial, minimalist white architectural interior with tall pillars, glossy black-and-white checkered reflective floor. A large amber glass perfume bottle with a gold cap dominates the foreground using dramatic forced perspective. In the background, a fashionable young male model wearing black sunglasses, a beige varsity jacket, matching shorts, white socks, and sneakers leans forward as if reaching for the bottle, creating an energetic lifestyle pose. Bright soft daylight, premium fashion campaign, clean luxury aesthetic, realistic reflections, subtle sparkles, high-end editorial photography, photorealistic, cinematic lighting, depth of field, ultra-detailed, 8K, Octane Render, luxury branding look. Leave negative space at the top for the headline "Own the Moment" and logo placement.

Visual concept

Visual concept

Create a 9:16 vertical fashion editorial poster with realistic slow-shutter photography and elegant minimal typography. Subject: [Person / Gender / Appearance] Outfit: [Fashion Styling] Scene: [Street / Minimalist Studio / Interior] Color palette: [Main Colors] Motion effect: [Moving Crowd / Walking Motion Blur / Layered Afterimages / Double Exposure] Title: [Main Title] Subtitle: [Short Subtitle] Keep one clear visual anchor while using authentic directional motion blur, ghosting, long-exposure trails, or layered afterimages to show movement and the passage of time. The motion should feel photographic rather than like a digital special effect. Preserve realistic anatomy and recognizable facial features while allowing moving figures, clothing, or surrounding people to dissolve naturally into soft blur. Use a clean, restrained background with generous negative space. Add subtle film grain, soft focus, imperfect exposure, low saturation, and natural light for an editorial photography feel. Typography should be minimal and integrated into the composition: only the main title and one short subtitle, using clean modern sans-serif typography. Do not include VOL numbers, dates, image numbers, or unnecessary information. Overall aesthetic: experimental fashion photography, slow-shutter motion blur, editorial magazine poster, cinematic and understated, realistic photography, refined but not overly commercial.
