Use the person from the reference image, preserve facial features 1:1, exact likeness. Concept: a refined fashion-style photo of a woman seated on a chair, fastening the strap of an expensive patent leather sandal on a thin stiletto heel. Subject: woman from the reference photo. Action & Pose: sitting on a chair, fastening the sandal, head slightly tilted about 15 degrees relative to the optical axis, relaxed facial muscles, direct gaze. Appearance: long, loosely wavy hair, black winged eyeliner, red lipstick. Wardrobe: carmine dress, expensive glossy patent leather sandals with thin stiletto heels. Framing & Composition: composition built on the golden ratio, the curve of the knee and shoulder line as the main guiding lines, minimized perspective distortion, focus on tactile realism of textures and the grace of the pose. Lighting: strong backlight in antique gold tone around 3200K placed directly behind the model, creating an intense halo and separating the figure from an obsidian gradient background; key light imitating a soft octabox around 5400K at a 45-degree angle; champagne-toned fill light softening harsh shadows. Camera & Optics: medium format sensor look, 100mm f/2.8 Macro lens, ultra shallow depth of field, focal plane precisely locked on the hands and sandal strap in the foreground, torso falling into soft bokeh. Visual Style: high-end realistic fashion photography with premium portrait optics rendering. Color Palette: dominant carmine tones in the dress and shoes contrasting with warm ochre skin tones. Details & Texture: pronounced microcontrast, visible skin pores and fine vellus hairs, light diffraction along contour edges creating a subtle glow, dense knit fabric with a faint nap, glossy leather shoe surface, dynamic range from deep fabric shadows to mirror-like highlights on the curve of the knee. Preserve: exact face, identity, and facial proportions from the reference image. Priority Instructions: exact facial similarity is critical; keep the same face; do not change identity, hairstyle length, makeup, pose concept, shoe type, or color relationships.
