ChatGPTUse the uploaded adult man's reference photo for his exact face, likeness and skin tone. Preserve his natural appearance. A separate scene reference controls composition and clothing only, never identity. Create a tightly cropped photographic portrait in a nearly black studio. The man gives a natural relaxed smile. A narrow, soft-edged warm light from the side illuminates the lower part of his face: one cheek, his smile, lips, jaw and a small area of neck. His eyes and upper face remain mostly concealed in deep shadow. Preserve the proportions of his own smile and mouth from the identity reference; do not replace them with an exaggerated advertising smile. Frame from just above the eyes to the upper chest, allowing the face to fill most of the vertical image. He wears a plain black open-collar shirt that merges gently into the background while retaining a faint edge near the collar. Use a close portrait-lens perspective without wide-angle distortion. The teeth should have natural shape and spacing, normal brightness and realistic separation from the lips. Control the light with a flag or shutter so it falls selectively across the mouth and cheek. The transition into shadow should feel physically gradual, with a soft feathered edge rather than a painted black mask. Keep small natural skin highlights and subtle texture on the lit cheek. Preserve deep neutral blacks and a restrained warm skin tone; no orange cast, beauty smoothing, artificial glow or HDR shadow recovery. Keep the mouth and lit cheek in focus with gentle depth falloff toward the collar and background. Maintain the correct jaw and neck anatomy. Do not reveal the whole face with fill light, add jewellery, invent hands near the face or turn the portrait into a silhouette. The smile and the small pool of warm light are the only focal points. Full-colour vertical 9:16 photograph. Add a small, subtle semi-transparent "promptybox.com" watermark at bottom right. No other text, logos, duplicated faces, malformed hands or plastic skin.
