彩色凝胶灯光男性肖像

生成一张 4:5 竖版彩色凝胶灯光男性肖像。中国男性模特站在黑色影棚背景前，穿黑色高领针织衫和深色长外套，半身到腰部构图，身体略侧，眼神看向镜头。左侧红色凝胶灯打在脸侧和肩部，右侧蓝色凝胶灯形成冷色轮廓光，中间保留自然肤色过渡。背景纯黑无文字，只有轻微烟雾层次。风格是现代商业男装大片，强对比但面部细节清晰。85mm 镜头，人物比例真实，肩颈自然，手部不进入画面。画面内不要出现任何可读文字、logo、水印、品牌或图形标识。

Create a 4:5 vertical male portrait lit by colored gels. A Chinese male model stands against a black studio background, wearing a black turtleneck sweater and a dark long coat, framed from half-body to waist, body slightly angled, eyes looking into the camera. A red gel light from the left hits the side of his face and shoulder, while a blue gel light from the right creates a cool rim light, with a natural skin-tone transition in the middle. The background is pure black with no text and only subtle haze layers. Modern commercial menswear editorial style, strong contrast but clear facial detail. 85mm lens, realistic proportions, natural shoulders and neck, hands outside the frame. No readable text, logo, watermark, brand, or graphic mark anywhere.
