想让 AI 编辑自己的照片来生成专业肖像照，但不会写提示词？谷歌官方提示技巧来了：

- 光线是关键
让 Nano Banana 添加“柔和但富有层次感的影棚灯光，勾勒面部轮廓并在眼中营造微妙眼神光。”

- 掌握最佳拍摄角度
让 Nano Banana 采用胸部以上的构图方式拍摄，头顶预留足够的裁剪空间。接着尝试指示 Nano Banana：拍摄时请直面镜头，展现自信又亲切的表情。

- 为理想职位而着装。
从衣着到发型，打造与你心仪职位完美契合的形象。例如："让拍摄对象穿上现代款西装外套，发型采用既随性又不失专业的风格，并清晰聚焦于几缕发丝。"

- 保持面部焦点
选择中性纯色摄影棚背景，让 Nano Banana 避开杂乱背景和干扰元素。

英文：A professional, high-resolution, profile photo, maintaining the exact facial structure, identity, and key features of the person in the input image. The subject is framed from the chest up, with ample headroom and negative space above their head, ensuring the top of their head is not cropped. The person looks directly at the camera, and the subject's body is also directly facing the camera. They are styled for a professional photo studio shoot, wearing a smart casual blazer. The background is a solid '#141414' neutral studio. Shot from a high angle with bright and airy soft, diffused studio lighting, gently illuminating the face and creating a subtle catchlight in the eyes, conveying a sense of clarity. Captured on an 85mm f/1.8 lens with a shallow depth of field, exquisite focus on the eyes, and beautiful, soft bokeh. Observe crisp detail on the fabric texture of the blazer, individual strands of hair, and natural, realistic skin texture. The atmosphere exudes confidence, professionalism, and approachability. Clean and bright cinematic color grading with subtle warmth and balanced tones, ensuring a polished and contemporary feel.
