  “prompt”: “Recreate the reference image as closely as possible: a fine-art, high-fashion, photorealistic black-and-white studio photograph on a clean mid-gray seamless backdrop. A white horse in the foreground, posed in a controlled prance/rear (front left leg lifted high, neck forward, ears alert), sharply detailed coat texture and musculature. On the horse sits a single rider fully draped in flowing sheer black fabric/veil and a long trailing black gown that billows dramatically to the right, creating large elegant fabric waves; the rider’s face is mostly obscured by the veil (no visible expression details). Minimal set, no props, no scenery—only the horse, rider, and seamless background. Soft diffused studio lighting with gentle falloff, smooth gradients on the backdrop, crisp edge separation between the white horse and black fabric. Monochrome grayscale with rich midtones, subtle filmic contrast, ultra-clean editorial look. No text, no logos, no watermark.”,
