在 Gemini 上生成 Nano Banana 👌。

Generation of Nano Banana 👌 on Gemini. Let's make it happen 😉 with ... PROMPT...... A medium waist-up portrait of a muscular adult male with a tan, olive skin tone, a groomed short beard, and slightly voluminous dark pompadour hair with natural texture, wearing a fitted deep black short-sleeve mock turtleneck, matching deep black trousers, and opaque dark square sunglasses completely concealing his eyes. His expression is serious, confident, and guarded with a closed neutral mouth. He is positioned in the center, leaning back with his torso turned roughly 30 degrees to the viewer's left, his broad, relaxed shoulders shifted back to distribute his weight into a pristine, thick cylindrical brushed metal handrail. His right hand is raised to his ear, thumb and fingers gripping the edges of a black smartphone in an organic, mid-motion gesture, a silver chain bracelet catching the light on his right wrist. His relaxed left hand rests naturally on his upper left thigh and hip area with fingers slightly curled, showcasing a bright silver chronograph watch with a cool blue dial. In the immediate foreground, the polished metal handrail spans horizontally across the frame. Behind him in the midground, clean, transparent glass balcony panels with a slight blue-cyan tint reflect the surroundings, partially obscuring thriving, out-of-focus small green foliage. The medium-depth background reveals a modern commercial building facade featuring large, highly reflective blue-tinted windows separated by perfectly smooth, satin-finished bright white vertical and horizontal cladding, with taut white shade awnings stretched over metal frames visible toward the top left. The scene is bathed in bright, highly directional midday natural sunlight from the top-front-left, approximately 45 degrees above and slightly left of the subject, establishing an energetic, polished, and professional mood with a high-contrast, split-complementary color palette of warm skin tones against cool architectural blues and crisp whites. This harsh, unmodified hard light creates deep black, crisply defined shadows under his chin, cast across his black chest from his phone and hand, under his arms, and beneath his right pectoral, while striking specular highlights gleam on his forehead, the bridge of his nose, taut forearm muscles, the metallic watch, the railing, and the background glass, with minimal ambient fill maintaining the deep structural shadows. Captured with a full-frame digital camera using an 85mm prime lens at f/2.8 from a slightly low angle, the composition is asymmetric, balancing the subject's mass leaning to the right with the architectural angles and open space on the left. The image boasts a photorealistic, high-end commercial fashion aesthetic with tack-sharp glossy focus on the subject and smooth, slightly blurred background elements, finished with contrast enhancement, slight desaturation of the greens to emphasize the cool blue and white tones, and lifted black points to preserve micro-detail in the dark clothing, beautifully framed in a 4:5 aspect ratio.

PROMPT...... 一张半身中景（腰部以上）人像肖像，画面中是一位肌肉发达的成年男性，肤色为古铜色偏橄榄色，留着修剪整齐的短胡须，略显蓬松的深色飞机头发型带有自然纹理，身穿一件合身的深黑色短袖半高领针织衫，搭配同色系深黑色长裤，并佩戴一副完全遮住双眼的不透明深色方形墨镜。他的表情严肃、自信、戒备，双唇紧闭、呈中性的直线。他位于画面中央，身体后倾，躯干向观察者左方旋转约 30 度，宽阔而放松的肩膀向后靠，将重心压在一条崭新、圆柱形、磨砂金属质感的厚实扶手上。他的右手抬起至耳侧，拇指与手指以自然、处于动作中间的方式握住一部黑色智能手机的边缘，右手腕上一条银色链式手镯在光线下熠熠生辉。他放松的左手自然地放在左上大腿与髋部区域，手指微微弯曲，展示出一枚带有冷蓝色表盘的亮银色计时码表手表。在紧贴前景处，抛光的金属扶手横向贯穿画面。在他身后的中景，是干净的透明玻璃阳台栏板，带有淡淡的蓝青色调，映出周围环境，局部遮挡着旺盛、虚化的绿色小型植物。中等景深的背景呈现出现代商业建筑的外立面，特征是巨大、高反光的蓝色调玻璃窗，其间以完全光滑、缎面处理的亮白色垂直与水平覆层相隔，画面左上方可见绷紧的白色遮阳棚覆盖在金属框架之上。场景沐浴在明亮、高指向性的正午自然阳光下，光线来自画面左前方上方——大约高于主体 45 度、并略偏主体的左侧，营造出充满活力、精雕细琢且专业的气质，整体采用高对比度、分裂互补的色彩搭配，将温暖的肤色与冷调的建筑蓝及清爽的白色形成对比。这种强烈、未加修饰的硬光在他的下巴下方、手机与手在黑色胸前投下的投影、手臂下方以及右胸肌之下形成深黑、轮廓清晰分明的阴影，同时在额头、鼻梁、绷紧的前臂肌肉、金属手表、扶手及背景玻璃上闪烁着夺目的高光，仅有极轻微的环境补光保留了深重而富有结构的阴影。使用全画幅数码相机搭配 85mm 定焦镜头在 f/2.8 光圈下、以略低的视角拍摄，构图是非对称的——以主体右倾的体量与左侧的建筑线条及留白相平衡。图像呈现摄影般逼真的高端商业时尚美学，主体处于锐利、鲜明的对焦，而背景元素平滑、略带虚化，并通过提升对比、略微降低绿色饱和度以突出冷蓝与白色调，同时提亮黑点（lifted black points）以保留深色衣物中的微细细节，整体以 4:5 的纵横比精美地呈现。
