下面是 15 个经过验证的 Nano Banana 提示词,可将普通自拍照变成适合 LinkedIn 的职业头像。内容按风格、光线和背景分类整理,你可以挑选一个直接粘贴到 Gemini 中使用。先上传照片,再粘贴提示词。大多数人只需稍作调整,例如修改西装颜色或背景选择即可。

粘贴前:决定成败的 3 件事

Nano Banana(Gemini 的图像编辑模型)在你的原始照片保留了足够信息时效果最佳。快速检查如下:

  1. 使用清晰的正面照片。 脸部要清楚可见、分辨率足够,且不要使用厚重滤镜。白天用手机拍的自拍,始终胜过模糊的聚会照片。
  2. 明确告诉它该保留什么。 下方每个提示词中最有用的一句话,都是类似“完全保持我的面部特征不变”的表达——这与多轮编辑中的“保持 X 不变”锁定技巧原理相同。没有这句,模型可能会逐渐变成一张不再像你的普通脸。
  3. 分步骤编辑。 如果第一次结果已经有 90% 正确,不要重写整段提示词——直接继续补充,例如“保持图片不变,但让背景更亮一些”。Nano Banana 很擅长处理迭代式编辑。

下面开始介绍提示词。

经典企业形象照

这是最稳妥的默认选择——也是招聘方和客户通常期待看到的风格。

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/科技风格

正式感稍弱,但依然专业可信。适合开发者、设计师、创业者,以及所有科技行业从业者。

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. 富有层次感的创始人风格肖像

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. 创意职业人士,彩色背景

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

只要背景保持虚化、光线足够柔和,环境背景在 LinkedIn 上也能有很好的效果。

7. 黄金时段户外形象照

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. 都市职业人士

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.

以光线为重点的版本

有时服装和背景都没有问题,问题只在于光线。这些提示词专门用来修正光线。

9. 修复强光/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. 伦勃朗式专业布光

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.

男女定制版本

上面的核心提示词不分性别——按需替换服装描述即可。以下是两个完整示例:

12. 男性版本——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. 女性版本——西装外套与柔和光线

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.

“不要添加浓妆”和“保持我的发际线”这两项要求很重要:没有它们,模型往往会过度美化,放在职业场景中会显得不真实。

清理与收尾提示词

14. 仅替换背景

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. 最终精修

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.

来自实际尝试的前后对比建议

如果你不只是编辑职业头像,我们的 Nano Banana 产品摄影模板也采用同样的复制粘贴格式,而提示词图库收录了更多可直接使用的模板。

常见问题

在 LinkedIn 上使用 AI 编辑过的照片可以吗?

对自己的真实照片进行优化——例如改善光线、背景或着装——已被广泛接受,在实际效果上与专业修图没有太大区别。真正容易引发问题的是照片已经不像你本人,因此这里的每个提示词都强调保留你真实的面部特征。

什么样的原始照片最适合 Nano Banana?

近期拍摄、光线充足、正面面对镜头,并且整张脸清晰对焦的照片。避免太阳镜、帽子、强滤镜和多人合照。输入照片的质量越高,生成结果就越真实。

为什么结果看起来像另一个人?

通常有两个原因:原始照片质量太低,模型无法准确锁定你的特征;或者提示词一次要求了太多改动。换一张更清晰的照片,并将较大的改动拆分成两到三轮连续提示。

我能只换衣服、不改变脸吗?

可以——这正是 Nano Banana 的优势之一。请明确写出“keep my face, hair, and skin tone exactly the same, change only my clothing to [outfit].” 提示词 14 展示了同样的模式如何用于背景替换。

最终图片应该使用什么尺寸?

导出 Gemini 提供的最大尺寸版本,然后裁剪为正方形。LinkedIn 建议至少使用 400 x 400 像素;更大的正方形裁剪只会给你留下更多调整空间。

结语

用 Nano Banana 制作一张好的 LinkedIn 头像,关键在于三步:从清晰的真实照片开始,明确告诉模型哪些部分必须保留,并通过小幅连续修改逐步完善,而不是用一段巨型提示词一次完成所有要求。选择与所在行业着装规范相符的上述提示词,替换服装细节,经过两三次迭代后,你就能得到一张可用的职业头像。
