极简蓝调摄影棚自信男士质感肖像

Create a minimalist studio portrait of a confident man seated casually on a simple geometric cube against a solid muted blue background. He sits with his legs apart and feet planted firmly on the ground, leaning slightly forward with both hands resting naturally near his knees, creating a grounded, relaxed, and quietly powerful posture. He has medium-length, textured dark hair styled with natural volume, a full, well-groomed beard, and an intense yet calm expression as he looks directly at the camera. His outfit is clean and understated: a soft off-white crewneck sweatshirt with a relaxed fit, paired with classic blue denim jeans featuring elasticated cuffs. He wears modern blue athletic sneakers with white accents, adding a casual, contemporary streetwear touch. The background is a smooth, seamless blue studio wall with no distractions, emphasizing simplicity and balance. Lighting is soft, diffused, and frontal, evenly illuminating the subject while gently sculpting facial features and fabric texture without harsh shadows. The color palette is cohesive and calm. Use aspect ratio 4:5.

创作一幅极简风格的肖像照，描绘一位自信的男士，他随意地坐在一张简单的几何立方体上，背景是纯色柔和的蓝色。他双腿分开，双脚稳稳地踩在地上，身体微微前倾，双手自然地放在膝盖附近，呈现出一种沉稳、放松而又内敛有力的姿态。他留着中等长度、富有质感的深色头发，造型自然蓬松，蓄着浓密而修剪整齐的胡须，眼神专注而平静地直视镜头。他的着装干净低调：一件柔软的米白色圆领运动衫，版型宽松，搭配经典蓝色牛仔裤，裤脚带有松紧设计。他穿着带有白色点缀的现代蓝色运动鞋，增添了一丝休闲的街头时尚感。背景是一面光滑、无缝的蓝色影棚墙，没有任何干扰，强调了简洁和平衡。灯光柔和、漫射且正面，均匀地照亮主体，同时轻柔地勾勒出面部特征和织物纹理，没有生硬的阴影。整体色彩搭配和谐而平静。使用 4:5 的宽高比。
