高端黑白肖像海报

创作一张高端时尚大片风格的人像海报，画面中只有一位胸部以上的主体，微微仰头，视线望向镜头之外，神情平静而自信。采用高反差黑白人像，面部细节清晰，棚拍光线柔和，并带有轻微胶片颗粒。将人像置于一个大型居中的彩色矩形内（从珊瑚粉、翡翠绿、芥末黄、宝蓝或深红等鲜明背景色中选择一种），矩形周围留出宽阔的暖象牙白／米白色纸张边框，并带有细腻的复古纹理。
沿左侧边缘竖向放置一个大型半透明数字“10”，颜色与背景色调相配。字体设计优雅简约。在右下角用与背景相同的点缀色，添加主体的手写签名。主体穿着简单的黑色圆领毛衣，不带标志或图案。
整体美学应融合奢华杂志封面与现代运动／时尚大片品牌风格：极简的瑞士风格版式、高端字体、干净留白、平衡构图、历久弥新的设计、哑光纸张纹理、细微印刷瑕疵、电影感光线、极致锐利的焦点、单色人像与局部彩色背景相结合，精致且具有标志性。

Create a premium editorial portrait poster featuring a single subject from the chest up, looking slightly upward and away from the camera with a calm, confident expression. Use a high-contrast black-and-white portrait with crisp facial detail, soft studio lighting, and subtle film grain. Place the portrait inside a large centered colored rectangle (choose a single bold background color such as coral pink, emerald green, mustard yellow, royal blue, or crimson) surrounded by a wide warm ivory/off-white paper border with a subtle vintage texture.
Add a large semi-transparent number "10" vertically along the left edge in a matching tone of the background color. Keep the typography elegant and minimal. Place a handwritten signature of the subject in the bottom-right corner using the same accent color as the background. The subject wears a simple black crewneck sweater with no logos or patterns.
The overall aesthetic should feel like a luxury magazine cover meets modern sports/editorial branding: minimalist Swiss-inspired layout, premium typography, clean negative space, balanced composition, timeless design, matte paper texture, subtle print imperfections, cinematic lighting, ultra-sharp focus, monochrome portrait with selective color background, sophisticated and iconic.
