Black Stallion Equestrian Portrait in Monochrome

Using the uploaded photo, create an ultra-realistic vertical 4:5 luxury equestrian portrait of the same man standing beside a muscular black stallion in a mist-covered field at dawn. KEEP — Preserve the man's exact facial identity and recognizable facial structure, including forehead shape, eyebrow placement, eye shape and natural eye colour, nose bridge and tip, lip shape, cheeks, cheekbones, jawline, chin, ears, facial width and natural asymmetry. Keep his original skin tone translated faithfully into grayscale, visible pores, fine skin texture, natural marks, authentic age and original expression. Preserve his hairline, hairstyle, hair density, facial hair if visible, neck length, shoulder width, body build and limb proportions. Do not substitute a generic fashion model or reconstruct his face. CHANGE — Dress him in a loose white linen shirt with an open collar, tailored light-gray trousers, polished black leather boots and a minimal wristwatch. Position him standing naturally beside the horse, with one hand resting gently against its neck and the other holding the reins. Give the stallion a glossy black coat, defined shoulder muscles, an expressive eye, pointed ears and a flowing mane. Keep its anatomy, hoof placement and body proportions realistic. SCENE — Place both subjects in an open meadow during early morning, with softly blurred grass and distant tree silhouettes disappearing into layered silver-gray fog. Keep the man and horse fully visible, with believable relative scale, grounded feet and hooves, and natural contact between his hand and the horse's neck. LIGHT — Use diffused dawn backlight from behind and slightly to one side, combined with gentle frontal fill. Match the illumination across the man's face and the horse's coat so neither subject looks pasted into the environment. Preserve facial detail beneath the brow and along the jaw. CAMERA — Simulate a professional full-frame camera with an 85mm lens at f/2.8, positioned around chest height. Use a natural perspective, moderate background compression and enough depth of field to keep both faces sharp. GRADE — Apply pure black-and-white toning, deep but detailed blacks, clean shirt highlights, smooth mid-gray transitions and restrained 35mm film grain. Retain visible skin pores, individual horse hairs and realistic linen weave. OUTPUT — Render at a vertical 4:5 aspect ratio, preferably 2048 × 2560 pixels or higher, with crisp subject detail and no text or watermark. DO NOT slim the face, whiten the skin, change eye colour, smooth skin into plastic, alter age, reshape facial features, invent jewellery or tattoos, distort hands, duplicate limbs or create anatomically incorrect horse legs.
