高对比度单色肖像提示
一个极其详细的提示，用于生成一张高对比度黑白艺术工作室肖像，要求精确复制参考图像中主体的身份、面部特征和表情。它指定了复杂的布光设置（低调、定向柔光箱）和构图（紧凑的垂直裁剪、“思想者”姿势）。

中文提示词
根据上传的参考图像，创作一幅引人注目、超细节、高对比度的黑白（无彩色）肖像。主体的面部结构和身份必须与参考图像精确匹配——准确复刻骨骼结构、眼睛形状、鼻子比例、下颌线清晰度、胡须密度（如果存在）、发际线和整体面部对称性。保持真实的皮肤纹理和自然特征，不进行人工平滑处理。 主体与表情 一位成熟、自信的男性，面部结构坚毅，双眼深邃，直视镜头。表情应严肃、沉思，并带有沉静的权威感。保留自然的皮肤细节，如毛孔、细纹和微妙的纹理，以增强真实感。眼神应专注而内省，而非咄咄逼人。 面部毛发（自适应） 如果参考图像中存在面部毛发，请精确复刻其密度、长度、形状和边缘。保持自然的色调变化（如果适用，包括花白）。胡须线条应干净且有结构感。 如果面部干净无须，请保留真实的皮肤纹理和下颌线条。 发型（自适应） 精确匹配参考图像中的发型——包括发量、方向、发际线和纹理。头发应看起来自然，具有可见的发丝细节和来自顶部定向照明的微妙高光。 姿势 经典的“思考者”姿势。一只手抬起托住下巴，拇指沿下颌线，食指略微弯曲。关节和肌腱应有微妙的定义，以增强真实感。手部应清晰对焦，具有可见的皮肤纹理和自然的色调渐变。 🔥 灯光与技术风格（精确定制） 低调的艺术工作室摄影，采用受控的高对比度塑形。 • 主光源位于略高于眼睛水平并略微偏向观者左侧的位置，向下倾斜以创建强烈的高平面高光。 • 光线柔和但有方向性（大型柔光箱或柔光罩），产生清晰的边缘定义，而无生硬的削波。 • 高光集中在前额中央、鼻梁、上颧骨、胡须纹理和手部上平面。 • 眉骨下方和颧骨处有微妙的阴影塑形，以增强骨骼结构。 • 面部阴影侧保持深沉，但不过度压暗——保持受控的中间调细节。 • 来自正前方的少量补光，以保持面部对称性，同时保留深度。 • 头发边缘和外侧肩膀处有非常微妙的轮廓分离，以防止与背景融合。 • 眼神光居中且自然——双眼中有一个小而柔和的矩形反射。 • 背景为纯黑色，无任何可见纹理，吸收所有溢出光线。 对比度应高但精致——无过曝高光，无浑浊的黑色。色调过渡干净。 构图 紧凑的垂直头部和肩部特写（推荐肖像方向，4:5 比例）。主体对称居中，呈现正式、平衡的构图。
原始提示词
Create a striking, ultra-detailed, high-contrast monochrome lack-and-white) portrait based on the uploaded reference image. The subject’s facial structure and identity must match the reference precisely accurately replicate bone structure, eye shape, nose proportions, jawline definition, beard density (if present), hairline, and overall facial symmetry. Maintain authentic skin texture and natural features without artificial smoothing. Subject & Expression A mature, confident man with a strong facial structure and deep-set eyes looking directly into the camera. Expression should be serious, contemplative, and quietly authoritative. Preserve natural skin details such as pores, fine lines, and subtle texture for realism. The gaze should feel focused and introspective, not aggressive. Facial Hair (Adaptive) If facial hair is present in the reference image, replicate it exactly — density, length, shape, and edges. Maintain natural tonal variation (including salt-and-pepper graying if applicable). Beard lines should be clean and structured. If clean-shaven, preserve realistic skin texture and jaw definition. Hairstyle (Adaptive) Match the hairstyle from the reference image exactly — volume, direction, hairline, and texture. Hair should look natural with visible strand detail and subtle specular highlights from overhead directional lighting. Pose Classic “thinker” pose. One hand raised to the chin with thumb along the jawline and index finger slightly curled. Knuckles and tendons subtly defined for realism. Hand in sharp focus with visible skin texture and natural tonal gradation. 🔥 Lighting & Technical Style (Accurately Customized) Low-key fine-art studio photography with controlled high-contrast sculpting. • Primary key light positioned slightly above eye level and slightly toward the viewer’s left, angled downward to create strong top-plane highlights. • Light is soft but directional (large softbox or diffused beauty dish), producing crisp edge definition without harsh clipping. • Strong highlight concentration on forehead center, nose bridge, upper cheekbones, beard texture, and the top planes of the hand. • Subtle shadow shaping under the brow ridge and cheekbones to enhance bone structure. • The shadow side of the face remains deep but not fully crushed — maintaining controlled midtone detail. • Minimal fill light from front-center to retain facial symmetry while preserving depth. • Very subtle rim separation along hair edges and outer shoulder to prevent blending into background. • Catchlights centered and natural — small, soft rectangular reflection in both eyes. • Background is fully black with zero visible texture, absorbing all spill light. Contrast ratio should be high but refined — not blown highlights, not muddy blacks. Clean tonal roll-off. Composition Tight vertical head-and-shoulders crop (portrait orientation, 4:5 ratio recommended). Subject centered symmetrically for a formal, balan
