十个覆盖真实形象照摄影师常用布光方案的实测提示词——干净的企业灰背景、柔和窗光、符合品牌调性的户外场景、高调影棚布光。每张卡片都展示未经修饰的肖像及其花费。
要交代的是布光方案，而不是人物的外貌吸引力。一个形象照提示词有五个部分，且顺序固定：取景、人物、着装、布光、背景。「企业形象照，胸部以上取景，一位四十多岁、留短银发的女性，身穿炭灰色西装外套内搭白衬衫，用一个大柔光箱从相机左侧45度打光，辅以一盏轮廓光，无缝中灰色背景布，85mm镜头f/2.8光圈，眼神锐利，皮肤质感自然。」这里的每一个分句都对应摄影师在现场做出的一个决定，模型也会对这五个部分都作出响应。
有两个短语值得牢记。「皮肤质感自然，毛孔清晰可见，无美颜磨皮」能防止模型生成那种一眼就能看出是AI的塑料感、磨皮过度的脸。而「85mm镜头f/2.8光圈」能带来专业肖像应有的适度背景虚化，而不是手机人像模式那种夸张的糊化效果。本页每一张形象照都是旁边提示词在BananaBanana上未经修饰的首次生成结果。图中人物并非真实存在——关于使用你本人照片的问题，见下方FAQ。
老实说，在很多日常场景下确实可以：演讲嘉宾简介、小公司团队页面、会议胸卡、个人网站。一次影棚拍摄要花几百美元，耗时半天；而这些图片只需几美分、二十秒就能生成，在形象照实际展示的尺寸下，两者的差别根本看不出来。它失效的场景，是任何需要「可核实确为本人」的用途——媒体证件、受监管的职业资质页面、身份证件照。
另一个诚实的局限是：纯文字生成的形象照，照的是一个并不存在的人。如果你需要自己的脸，工作流程要换一种：上传一张自己现有的、还不错的照片，用编辑功能围绕它重新设定布光、背景和着装，而不是直接从文字生成。这样既能保留你的相貌特征，又能获得影棚质感。这么做的前提是：只能用你本人的照片，或者已经取得当事人同意的照片——为未经同意的人生成逼真肖像，不管用的是什么工具，都是不妥的。
下面每张图片都是所在卡片提示词的未修输出——没有从几十次尝试里挑好的，也没有修图。模型徽标标明了它由什么生成、花了多少钱。
Professional corporate headshot, chest-up, of a woman in her forties with short silver hair, wearing a charcoal blazer over a crisp white shirt. Large softbox 45 degrees to camera left, subtle hair light from behind, seamless mid-grey studio backdrop with a soft falloff. 85mm lens at f/2.8, sharp focused eyes, natural skin texture with visible pores, no beauty retouching, calm confident expression, slight smile.
Editorial business portrait of a man in his thirties with a short beard, wearing a navy knit sweater, seated at an angle beside a large window in a bright office.

Soft window light from camera right, gentle shadow gradient across the wall behind him. 50mm lens at f/2, natural skin texture, easy half-smile, informal startup team-page style.
「皮肤质感自然，毛孔清晰可见，无美颜磨皮」这一句话，就是逼真形象照和那种暴露AI身份的塑料光滑脸之间的分水岭。省掉它，再好的布光也救不了这张图。
「一个大柔光箱从相机左侧45度打光，辅以一盏轮廓光」是一条真正的指令。「专业布光」不是——它会得到模型随意发挥的结果，这就是为什么这样生成的一组照片永远对不上。
85mm配f/2.8能带来那种恰到好处、不夸张的背景分离感，看起来很专业。35mm配f/2.8则适合需要保留环境信息的人像。不写镜头这一句，往往会得到手机人像模式那种发糊、发际线边缘涂抹感明显的效果。
固定布光、背景和镜头这句话，只改人物描述部分。十张统一布光方案的形象照看起来像一家公司；十张风格各异的照片看起来像临时拼凑的图库照片。
纯文字提示词做不到——那样生成的是一个不存在的人。请在生成器中上传自己现有的照片，并描述想要的改动：「完全保留这张脸，把背景换成中灰色影棚背景布，用相机左侧的柔光箱重新打光，外套改成炭灰色」。这样既能保留你的相貌，又能获得影棚效果。
不是。本页每一张肖像都完全由文字生成，因此没有一张脸属于真实存在的人。这也是需要坚守的道德底线：只为自己或已经同意的人生成逼真肖像。
对于职业主页来说，基于本人真实照片重新风格化的图是安全的，也越来越常见。但把一张完全合成的脸当作自己展示，属于身份造假，可能导致主页被处理。任何需要身份核实的场合——媒体证、受监管的职业注册资料、身份证件——都需要真实照片。
把取景收紧一些。胸部以上或肩部以上取景的形象照完全避开了手部，而手部正是大多数肖像瑕疵的高发区。如果需要腰部以上、露出手部的构图，要么给手安排一个具体动作——「双臂交叉」「一只手放在桌上」——要么打算好之后再做一轮修图。
明显是Nano Banana Pro——皮肤质感、眼中的高光点和头发细节都保持得很好，而更便宜的模型在这些地方开始出现磨平的痕迹。Nano Banana 2对大多数团队页面来说已经足够接近；Lite（$0.03）最适合在正式生成前用来测试构图。
