AI Prompt for Realistic Fashion Portrait with Light and Shadow

"A professional, high-end photograph emphasizing the physical interplay of light and shadow on real surfaces. A young woman stands with her back to the camera, body turned slightly to the side. Her posture is calm and composed. Her back is fully visible. She wears an elegant backless evening dress made of matte silk with a subtle {argument name="dress color" default="gray-blue / ice-blue"} tone.The fabric is thin, fluid, naturally draped, with fine shoulder straps that follow the natural line of her shoulders and spine. No exaggerated sheen — true silk texture with gentle light absorption. Soft, irregular shadows from tree branches and leaves fall naturally across the skin of her back, shoulders, and the dress fabric, as if warm sunlight is filtering through foliage and a nearby window frame. The shadow patterns are organic, imperfect, and uneven — realistic, not decorative. Her head is slightly turned, revealing only a partial profile. A thin gold hoop earring catches a small, sharp highlight from the sunlight. No facial emphasis — the face remains secondary and partially obscured. A strong, clearly defined shadow of her head and shoulders is cast onto a dark gray-blue matte wall in front of her, creating graphic contrast and visual depth. The wall has a minimal surface with subtle rectangular geometric highlights caused by directional light. An elegant, narrow vertical mirror hangs on the wall. In the reflection, a small, neat bouquet of {argument name="flower type" default="cornflowers"} is visible, held gently in front of her body — understated, quiet, symbolic. LIGHTING Strong, low, warm directional sunlight coming from the side. High contrast between illuminated skin and deep shadow. Distinct leaf shadow patterns visible on skin and fabric. No artificial lighting, no beauty lighting, no glow. CAMERA Medium shot from behind, slightly offset to the side. Camera positioned at shoulder height. 50–85mm photographic look. Shallow depth of field — her back and earring in crisp focus, background softly blurred. Natural perspective, no distortion. MOOD & ATMOSPHERE Quiet, intimate, cinematic. Refined minimalism. Poetic realism. Feels like a carefully observed moment, not a staged pose. No stylization, no fantasy — realism driven by light, texture, and composition. QUALITY NOTES Natural skin texture visible (pores, subtle tonal variations). No smoothing, no retouching. No glamour filters. True-to-life color grading with restrained saturation."
