街拍肖像的灵魂是抓拍感——主体没意识到相机、用自然光、表情在某个未完成的瞬间。写”街上的一个人”出来的是摆拍微笑的图库素材。下面 10 个模板把主体职业、可用光、报道镜头都锁死，让出图像纪实摄影，不像 Instagram。
一个好 Prompt 通常包含什么
街拍肖像必须含的 6 件事：
- 主体背景：职业 + 地点（港口渔民、晨市菜贩）
- 抓拍线索：
unaware of camera、mid-thought expression、looking down at hands - 只用现场光：晨雾、黄昏金光、阴天、单只店铺灯泡
- 皮肤质感：
natural skin with visible pores and small creases - 报道镜头：35mm f/2 最常用；50mm f/2 收紧些
- 胶片色调：
Kodak Tri-X、Fuji 400H、Portra 400—— 胶片型号锁纪实感

- 摆拍微笑 + 直视镜头 —— 抓拍感全无；写
unaware of camera或looking down at hands - 街景用影棚灯 —— 毁纪实调；只能用现场光
- 长焦镜头 —— 压缩街道空间；保持 35mm f/2 到 f/2.8
- 不写职业和地点 —— 出来的是图库素材
- 不写胶片型号 —— Tri-X / Portra / Fuji 是纪实色调和颗粒的关键
下一步怎么改得更好
- 想要硬纪实：35mm f/2 + Tri-X 黑白 + 轻微颗粒 + 现场光
- 想要人文暖调：35mm f/2 + Portra 400 + 柔和金光 / 阴天
- 想要动作抓拍：加
slight motion blur in one limb或mid-action with hands on... - 想要环境叙事：35mm 广一点，背景虚化但可读，3:2 比例
- 系列图一致：锁胶片 + 镜头，只换主体和地点
常见问答 (FAQ)
Q: 街拍出来总像摆拍？
A: 写明主体在做什么 —— mending a net、arranging produce、wrapping a bouquet。加 unaware of camera 或 mid-thought expression。动作 + 没察觉镜头就是抓拍。
Q: 背景出来很假怎么办？
A: AI 街景容易糊成一团。锚定具体地点 —— working harbor、open-air morning market、narrow alley with hand-painted walls。背景留一点虚化，细节错位就被遮住。
Q: 纪实选黑白还是彩色？
A: 黑白（Tri-X）= 硬核经典纪实。彩色（Portra 400 / Fuji 400H）= 温暖人文。按调性选，不要默认。一套系列里混用会断掉连贯感。
Q: 街拍主体怎么避免”模特脸”？
A: 加 natural skin with visible pores and small creases，选职业本身就有岁月感的（渔民、工人、菜贩）。负面词加 airbrushed, glamour, smooth skin。
Q: 街拍用什么比例？
A: 3:2 = 35mm 胶片完整报道感。4:5 = 编辑式肖像裁切。避免 1:1 —— 方框毁掉街道的纵深感。
