快速回答
Nano Banana AI 能協助您製作逼真的護照式照片，照片中臉部居中、背景純色、表情自然，且光線均勻。此功能適用於個人頭像、模擬圖、內部證件預覽、履歷表及設計素材。 若用於正式護照或簽證申請，請使用原始且未經編輯的照片，並遵循相關政府機關的規定。.
What Is Nano Banana AI?
Nano Banana is the name commonly used for Gemini’s native image generation and editing capabilities. According to Google’s Gemini API image generation documentation, Nano Banana refers to multiple image models, including Nano Banana 2, Nano Banana Pro, and Nano Banana based on Gemini image models.
對於創作者和行銷人員而言，Nano Banana 之所以實用，是因為它能夠根據文字提示生成圖片、透過自然語言編輯上傳的圖片、在多次修改過程中保持主題的一致性，並創建逼真的攝影棚風格視覺效果。Google 還指出，生成的圖片會包含 SynthID 水印。.
簡單來說，Nano Banana AI 是一款影像生成與編輯工具，能夠將提示語或上傳的參考照片轉化為精緻的視覺作品。以護照照為例，這意味著您可以要求生成正面頭像、表情自然、純色背景、光線均勻，以及逼真的照片品質。.
Can You Use Nano Banana for Passport Photos?
You can use Nano Banana for passport-style photos, but you should not assume the result is acceptable for an official passport application.
Use Nano Banana for:
- LinkedIn profile photos
- Resume headshots
- Internal company ID previews
- Student ID mockups
- App UI examples
- Design placeholders
- Creative passport-style portraits
Do not rely on Nano Banana alone for:
- Official U.S. passport submissions
- Visa applications
- Government ID applications
- Legal identity documents
- Any document photo where the agency requires an original, unedited image
The U.S. Department of State says passport photos should be original and unedited, and it warns against changing photos with software, filters, phone apps, or artificial intelligence. That is why this guide uses the phrase “passport-style photo” instead of promising an officially accepted passport photo.
Official Passport Photo vs Passport-Style AI Image
| 使用案例 | Can Nano Banana help? | 最佳實踐 |
|---|---|---|
| LinkedIn or resume photo | 是 | Use a realistic headshot prompt with neutral lighting and no face reshaping. |
| Company badge preview | 是 | Generate a consistent ID-style look for mockups before final photography. |
| Student ID sample | 是 | Use it for design previews, not official identity verification. |
| App or website placeholder | 是 | Use synthetic people or approved reference images. |
| U.S. passport application | Not for the final submitted photo | Use a recent real photo that has not been digitally changed. |
| Visa or government ID | Check first | Requirements vary by country and agency. |
Key takeaway: Nano Banana is a good tool for creating passport-style visuals. It is not a shortcut around official photo rules.
Best Nano Banana Prompts for Passport-Style Photos
Use these prompts for non-official passport-style photos. If you upload a real person as a reference, include the line “preserve the person’s real facial features and identity” so the model does not over-edit the face.
| 場景 | 可直接複製的提示語 |
|---|---|
| 簡潔俐落、專業的頭像照 | Create a passport-style headshot of the uploaded person. Preserve the person’s real facial features and identity. The person faces the camera directly with a neutral expression, both eyes open, mouth closed, shoulders visible, plain off-white background, even soft lighting, natural skin tone, realistic camera photo, no beauty filter, no face reshaping. |
| 商務個人照 | 為上傳的人物製作一張專業的證件照風格頭像。須保留人物身分特徵與臉部比例。該人物身穿淺色襯衫外搭深色西裝外套，正對鏡頭，表情自然，頭部與肩膀居中，背景為純白色，採用均勻的攝影棚燈光，呈現逼真的照片質感。. |
| 學生證風格的照片 | 請為上傳的人物製作一張逼真的學生證風格證件照。須保留原人物的面容與年齡。服裝應為休閒整潔的風格，目光直視鏡頭，表情自然，肩膀需清晰可見，背景為素色淺灰色，光線柔和均勻，不得進行修圖，亦不得使用風格化濾鏡。. |
| 員工證照片 | 為上傳的人物製作一張員工證風格的頭像照。須保留當事人身分特徵。該人物應穿著簡約的專業上衣，面朝前方，表情自然，臉部居中，肩膀清晰可見，背景為純白色，膚色還原準確，光線均勻，影像呈現自然逼真。. |
| 應用程式原型設計（直式） | Create a passport-style portrait for an app interface mockup. The person faces the camera directly, neutral expression, shoulders visible, plain off-white background, realistic lighting, clean edges, natural skin texture, no face distortion, no exaggerated retouching. |
Pro prompt modifier:
plain off-white seamless background, soft frontal studio lighting, natural skin tone, realistic camera photo, centered head and shoulders, no shadow on the face or backgroundHow to Create a Passport-Style Photo with Nano Banana
Step 1: Choose the right use case
Before generating anything, decide whether the image is for official or non-official use. If it is for a profile photo, ID mockup, resume, team page, or design preview, Nano Banana is a strong fit. If it is for an official passport or visa submission, check the government rules first and use an original photo if required.
Step 2: Upload a clear reference photo
Use a sharp, front-facing image with good lighting. Avoid blurry, heavily filtered, side-angle, or cropped photos. If the reference image is poor, the AI result will usually need more correction.
Only upload photos you have permission to use. For business or team projects, get consent before using employee or customer photos.
Step 3: Paste a prompt with identity protection
Start with one of the prompts above. If the image is based on a real person, include:
Preserve the person's real facial features and identity.Also add negative instructions such as:
no beauty filter, no face reshaping, no age change, no stylized effect
Step 4: Control the background and lighting
For a classic passport-style look, ask for a plain white, off-white, or light gray background. For professional profiles, off-white or light gray often looks more natural than pure white.
Use lighting instructions such as:
soft even frontal lighting, no harsh shadows, accurate skin tone, realistic studio photo
If the image changes the person’s identity, regenerate it with a stricter prompt.

Nano Banana Model Tips for 2027
Google’s current image generation documentation describes Nano Banana as a family of Gemini native image generation models. The most relevant practical difference for this use case is quality versus speed.
| Model name in Google docs | Practical role | Best fit for passport-style images |
|---|---|---|
| 奈米香蕉 2 | Speed and high-volume generation | Batch drafts, fast variations, internal mockups |
| 奈米香蕉專業版 | Professional asset production and complex instructions | Higher-quality profile assets and polished marketing visuals |
| 奈米香蕉 | Fast image generation and editing | Quick edits and simple passport-style headshots |
If your platform offers multiple Nano Banana options, start with the faster model for drafts and use the higher-quality option for the final visual.
Common Mistakes to Avoid
Mistake 1: Calling the output an official passport photo
Use “passport-style photo” unless you are referring to a real photo that meets official agency rules. This keeps the article accurate and protects user trust.
Mistake 2: Over-editing the face
Passport-style photos should look natural. Avoid prompts that make the face younger, slimmer, smoother, more symmetrical, or more glamorous.
Mistake 3: Using a busy background
Background objects, textures, gradients, shadows, and decorative walls weaken the ID-style look. Keep the background plain.
Mistake 4: Cropping too tightly
A good passport-style image shows the full head and shoulders. If the forehead, hair, ears, chin, or shoulders are cut off, regenerate or recrop the image.
Mistake 5: Ignoring official country rules
Passport and visa photo requirements vary. The U.S. checklist is useful for U.S.-style formatting, but other countries may have different sizes, background colors, face proportions, or digital submission rules.
