15 条 Nano Banana 提示词：把自拍改成专业的 LinkedIn 职业头像（复制即用）

复制即用的 Nano Banana 提示词，专门做 LinkedIn 职业头像：几种商务形象照风格、布光方案、背景选择，外加男士、女士两套现成版本，挑一条粘贴进 Gemini 就能用。

下面 15 条 Nano Banana 提示词都实测过，能把一张普通自拍改成可以直接放上 LinkedIn 的职业头像。按风格、光线和背景分好了类，挑一条直接粘贴进 Gemini 就行。先上传照片，再粘贴提示词。大多数人只需要小改几处（比如西装颜色、背景）就够了。

粘贴之前：决定成败的 3 件事

Nano Banana（Gemini 的图像编辑模型）要从原图里拿到足够多可以“保住”的信息，效果才会好。快速自查一下：

1. 用清晰的正面照。 脸要看得清楚，分辨率过得去，别加重滤镜。白天用手机拍的自拍，永远比一张模糊的聚会照好用。
2. 告诉模型要保留什么。 下面每条提示词里最有用的一句，都是 “keep my facial features exactly the same”（五官完全保持不变）的某种说法——和多轮编辑里的“保持 X 完全一致”锁定法是同一个道理。少了这一句，模型可能会慢慢把你改成一张大众脸，看着就不像你了。
3. 分步修改。 如果第一次的结果已经对了 90%，别重写整条提示词，接着回一句就行，比如 “same image, but make the background lighter”（图不变，背景再亮一点）。Nano Banana 很擅长这种一步步迭代的修改。

下面进入正题。

经典商务形象照

这是最稳妥的默认选择，也是招聘方和客户最习惯看到的风格。

1. 标准影棚形象照

Transform this photo into a professional corporate headshot. Keep my facial features, skin tone, and expression exactly the same. Dress me in a tailored navy blazer over a white shirt. Plain light gray studio background, soft even lighting, shallow depth of field, shot on an 85mm portrait lens. Head and shoulders framing, looking directly at the camera.

2. 温暖亲和版

Edit this photo into a friendly professional headshot. Preserve my face and natural smile exactly. Charcoal blazer, no tie, slightly relaxed posture. Warm soft window light from the left, softly blurred neutral office background. Head-and-shoulders crop, genuine approachable expression.

3. 高管黑白肖像

Convert this photo into a black-and-white executive portrait. Keep my facial features identical. Dark suit jacket, crisp white shirt. Dramatic but flattering studio lighting with a subtle rim light on one side, deep gray seamless background. Sharp focus on the eyes, timeless editorial style.

现代创业公司／科技风

没那么正式，但依然专业可信。适合开发者、设计师、创始人，以及所有做科技的人。

4. 商务休闲，虚化办公室背景

Turn this photo into a modern professional headshot. Keep my face, hair, and skin tone unchanged. Dress me in a plain dark crew-neck sweater. Background: a bright modern open-plan office, heavily blurred with natural bokeh. Soft daylight, relaxed confident expression, chest-up framing.

5. 有纵深感的创始人肖像

Edit this into a startup founder portrait. Preserve my exact facial features. Untucked oxford shirt, sleeves slightly rolled. I'm standing at a three-quarter angle, face turned to camera. Background: floor-to-ceiling windows with soft city light, strongly out of focus. Natural light, editorial magazine quality.

6. 创意从业者，纯色背景

Transform this selfie into a creative professional headshot. Keep my face identical. Simple black turtleneck. Solid muted teal studio background, clean soft lighting with a gentle shadow gradient. Minimalist composition, head and shoulders, subtle confident smile.

户外与环境人像

只要背景够虚、光线够柔，带环境的人像放在 LinkedIn 上也很出彩。

7. 黄金时刻户外形象照

Edit this photo into an outdoor professional portrait taken at golden hour. Keep my facial features and expression exactly as they are. Business casual blazer over a plain t-shirt. Background: tree-lined street softly blurred, warm late-afternoon sunlight from behind creating a gentle hair light. Natural, flattering, chest-up crop.

8. 都市职场人

Turn this photo into a city professional headshot. Preserve my face precisely. Dark tailored coat over a shirt. Background: modern glass architecture, defocused, cool overcast daylight for soft even skin tones. Slight angle to the camera, composed and confident.

主打光线的版本

有时候服装和背景都没问题，问题出在光线上。下面这几条专门修光线。

9. 修正硬光和阴影

Edit this photo: keep everything about my face, clothing, and pose the same, but relight the image with soft diffused studio lighting. Remove harsh shadows under the eyes and nose, even out the skin exposure, add a subtle catchlight in the eyes. Do not smooth or alter my skin texture unnaturally.

10. 伦勃朗光职业照

Relight this portrait with classic Rembrandt lighting: key light from the upper left, a small triangle of light on the shadowed cheek. Keep my facial features and clothing unchanged. Neutral dark gray background, refined and serious tone.

11. 明亮的高调风格

Edit this into a high-key professional headshot. Keep my face exactly the same. Bright white background, soft wraparound lighting with no hard shadows, light-colored blazer. Clean, optimistic, modern corporate style.

男士、女士定制版

上面的核心提示词男女通用，按需替换服装那一句就行。下面是两个完整示例：

12. 男士版——经典西装

Transform this photo into a professional LinkedIn headshot of me. Keep my facial features, beard, and hairline exactly as they are. Dark gray suit, white shirt, no tie, well-fitted. Neutral warm-gray studio background, soft key light with gentle fill, head-and-shoulders framing, calm confident expression.

13. 女士版——西装外套配柔光

Edit this photo into a professional LinkedIn headshot. Keep my facial features, hairstyle, and makeup level exactly the same — do not add heavy makeup. Cream-colored blazer over a simple top, small stud earrings. Soft diffused lighting, light neutral background with gentle blur, shoulders-up crop, warm genuine smile.

“do not add heavy makeup”（不要加浓妆）和 “keep my hairline”（保留我的发际线）这两句很关键：少了这两句，模型往往会过度美化，放在职业场合就显得假。

清理与收尾提示词

14. 只换背景

Keep me exactly as I am in this photo — same face, hair, clothing, lighting on my face. Replace only the background with a softly blurred neutral office interior in light gray and warm wood tones. Match the background lighting direction to the light already on my face.

15. 最后精修一遍

Subtly retouch this headshot for LinkedIn: remove stray hairs, reduce shine on the forehead, slightly brighten the eyes, clean up the collar. Keep skin texture natural and do not change my facial structure in any way. The result should look like a professionally retouched photo, not an AI image.

实测出来的前后对比经验

• 如果出来的人不像你， 多半是原图的问题：尺寸太小、角度太偏，或者脸被挡住了一部分。与其跟提示词较劲，不如换一张更清楚的照片重来。
• 如果衣服像是贴上去的， 加一句 “make the jacket fit naturally on my shoulders with realistic fabric folds.”（让外套自然贴合肩膀，带出真实的衣褶。）
• 如果皮肤有塑料感， 加一句 “preserve natural skin texture, visible pores, no airbrushing.”（保留自然肤质和可见毛孔，不要磨皮。）这一句就能解决大家吐槽最多的问题。
• 最后再按 LinkedIn 的要求裁切。 LinkedIn 的头像显示为圆形，所以先要求头肩构图、头顶留点空间，再裁成正方形。
• 生成 3–4 个版本， 挑眼睛最清晰的那张。眼睛清不清楚，决定了一张头像看起来像不像“真照片”。

如果你要修的不只是头像，我们的 Nano Banana 产品摄影模板也是同样的复制即用格式，提示词图库里还有更多现成的写法。

常见问题

LinkedIn 上用 AI 修过的照片，合适吗？

在自己真实照片的基础上改善光线、背景和着装，如今已是普遍接受的做法，效果上和请人专业修图差不多。真正会出问题的是照片已经不像你本人了——所以这里每条提示词都坚持保留你真实的五官。

什么样的原图最适合 Nano Banana？

最近拍的、光线充足、正对镜头、整张脸都清晰对焦的照片。别用戴墨镜、戴帽子、加了重滤镜的照片，也别用合照。原图质量越高，出图越真实。

为什么出来的像另一个人？

通常是两个原因之一：原图质量太差，模型抓不住你的特征；或者提示词一次要改的东西太多。换一张更清晰的照片，把大改动拆成两三条提示词分步来。

能只换衣服、不动脸吗？

可以，这正是 Nano Banana 的强项之一。直接写明 “keep my face, hair, and skin tone exactly the same, change only my clothing to [outfit].”（脸、头发和肤色完全保持不变，只把衣服换成[服装]。）第 14 条提示词就是把同样的写法用在了换背景上。

最终图片要多大尺寸？

导出 Gemini 给出的最大尺寸，再裁成正方形。LinkedIn 建议至少 400 x 400 像素；正方形裁得大一些，只是给你留出更多调整余地。

生成你自己的版本

想按自己喜欢的构图和风格，生成一版专属提示词？免费的 Nano Banana 提示词生成器里有一个 Portrait Style（人像风格）模式，预设就取自这套合集——选好风格，复制提示词就行。

结语

用 Nano Banana 做一张好的 LinkedIn 头像，关键就三步：从一张清晰的真实照片开始，明确告诉模型哪些要保留，再用小步追加修改慢慢调，而不是靠一条巨长的提示词一步到位。从上面挑一条符合你所在行业着装习惯的提示词，换掉服装细节，迭代两三次，就能得到一张能用的职业头像。
