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, balanced presence. Background is pure crushed black with no visible texture.
Color & Tonality
Pure black and white conversion with neutral tonal balance (no color tint).
Wide dynamic range — deep true blacks, bright clean highlights, and smooth midtone transitions.
Micro-contrast enhancement to emphasize skin and beard texture.
Depth of Field
Shallow depth of field with razor-sharp focus on eyes and front hand. Slight softness toward ears and far shoulder.
Wardrobe
Dark black crewneck sweater or minimalist top with matte texture that absorbs light and blends into background. Subtle rim separation on shoulder edge.
Quality & Mood
Cinematic fine-art portrait. Ultra-realistic. Editorial studio quality. 8K resolution. Sharp micro-details. Mood: powerful, introspective, refined, quietly dominant.
基于上传的参考图像，创作一幅引人注目、超细节、高对比度的单色（黑白）肖像。对象的面部结构和身份必须与参考图像精确匹配，准确复制骨骼结构、眼型、鼻子比例、下颌线轮廓、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，面部结构刚毅，眼窝深邃，直视镜头。表情应严肃、沉思且带有内在的威严感。保留自然的皮肤细节，如毛孔、细纹和微妙的纹理以追求真实感。眼神应显得专注且内省，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，需精确复制——密度、长度、形状和边缘。保持自然的色调变化（包括椒盐灰，如适用）。胡须线条应干净且有条理。如果是刮干净胡须的，保留逼真的皮肤纹理和下颌轮廓。
发型（自适应）：精确匹配参考图像中的发型——发量、方向、发际线和质感。头发应看起来自然，有可见的发丝细节和来自头顶定向照明的微妙高光。
姿势：经典的“思想者”姿势。一只手托在下巴上，拇指沿着下颌线，食指微曲。指关节和肌腱微妙地显现以增加真实感。手部清晰聚焦，可见皮肤纹理和自然的色调渐变。
🔥 光照与技术风格（精准定制）：低调Fine Art（艺术）工作室摄影，采用受控的高对比度塑光。
• 主光位于眼平面略上方，并略微偏向观众左侧，向下打光，以营造强烈的顶部平面高光。
• 光线柔和但具有方向性（大型柔光箱或带柔光罩的雷达罩/Beauty Dish），产生清晰的边缘定义，而无生硬的死黑 clipping。
• 高光集中在额头中心、鼻梁、颧骨上部、胡须纹理和手部顶面。
• 眉脊和颧骨下方的微妙阴影造型，以增强骨骼结构。
• 脸部的阴影侧保持深沉但未完全压死——保持受控的中间调细节。
• 来自正前方的极少补光以保持面部对称性，同时保留深度。
• 沿发际边缘和外肩有非常微妙的轮廓分离，防止与背景融合。
• 眼神光居中且自然——双眼中有小而柔和的矩形反射。
• 背景全黑，零可见纹理，吸收所有溢出光。对比度应高但精致——无过曝高光，无浑浊暗部。干净的色调过渡。
构图：紧凑的垂直头肩裁剪（肖像方向，建议比例为 4:5）。主体居中对称，营造正式、平衡的存在感。背景为纯粹的压死黑色，无可见纹理。
色彩与色调：纯黑白转换，具有中性色调平衡（无色偏）。宽动态范围——深邃的真黑色、明亮干净的高光和平滑的中间调过渡。微对比度增强，以强调皮肤和胡须纹理。
景深：浅景深，焦点在眼睛和前手上如剃刀般锐利。耳朵和远肩处略微柔和。
服装：深黑色圆领毛衣或极简主义上衣，具有哑光质感，吸收光线并与背景融合。肩部边缘有微妙的轮廓分离。
质量与氛围：电影感艺术肖像。超写实。编辑室质量。8K 分辨率。锐利的微观细节。氛围：强大、内省、精致、静默的统治力。
