判断一张人像是真摄影还是 AI 出的，灯光是最大破绽。泛泛的”studio portrait”会给你均匀全向的死光——额头、颧骨、下巴亮度全一样，真摄影师不会这么布光。下面 12 套模板把方向、硬度、色温显式锁死，换主体就能复用整组的灯光语言。配套见更广的 写实人像 Prompt。

这套 Prompt 适合用在哪

  • 编辑部 / 作者头像，需要统一灯光语言
  • 品牌官网的演讲嘉宾与创始人肖像
  • 想保持组图视觉统一、不想每张都重写 Prompt 的拍摄系列
  • 用 AI 肖像替代库存图，保持品牌一致
  • 真棚拍前的灯位预演

怎么调

镜头焦距一定要写（85mm 给压缩感和好皮肤、35mm 带环境）以及显式比例（3:1 好看、8:1 戏剧）——扩散模型默认会给死板的均光。一组照片只挑一个主光方向（左 / 右 / 上），不要混；多光源食谱看起来不真实，因为真摄影师很少同时打四盏灯。完整产线见 AI 写实人像工作流。

容易踩的坑

  • 没写材质词，皮肤变塑料感——一定加 natural pore detail、light freckles、subtle skin imperfections
  • 没写镜头，模型默认广角，脸会变形
  • 同一 Prompt 里灯光方向打架（light from left 和 rim from left 和 key from right 同时出现）
  • 背景比脸还亮，视线被背景拉走，眼睛失焦
  • 忘了写比例——不加 ratio 3:1 模型会平均成全向死光，一眼 AI
