什么是纳米香蕉及其人工智能照片修复功能
Nano Banana is Google’s family of conversational image models. Google’s image-generation documentation distinguishes Nano Banana 2, Nano Banana Pro, and the original Gemini 2.5 Flash Image model. For an iterative restoration workflow on GlobalGPT, start with Nano Banana 2 or Nano Banana Pro and keep the same source photo throughout.
用户可以修复老化或损坏的照片，同时保留细腻的细节并添加逼真的色彩。无论是刮花的黑白照片还是褪色的全家福，Nano Banana 只需几个简单的命令就能将其恢复到栩栩如生的状态。.
Before you upload the scan
Use the largest clean scan you have. Photograph a print straight-on in even light if scanning is not possible; glare and a tilted camera can hide more detail than the model can recover. Keep a separate untouched copy. Decide whether the result should remain black and white, and identify the face, handwritten note, badge, or garment detail that must not change.
老照片修复和上色分步指南
1 上传旧照片
选择要修复的受损照片或黑白照片。.
2 输入详细提示
例如 “修复这张老照片，去除划痕，自然着色”
3 生成恢复图像
Review the repaired image before accepting it. Nano Banana can reconstruct plausible details and suggest colors, but a convincing result does not prove that missing features or historical colors are accurate.
4 根据需要改进
使用其他提示来调整色调、亮度或特定细节，以获得完美的最终效果。.
Three restoration prompts you can adapt
Use one prompt for the dominant problem. Combining damage repair, colorization, a new background, and a different expression makes it harder to tell which edit caused a face to change.
Remove scratches while preserving the original portrait
Repair the scratches, dust, and small creases in this photograph. Preserve the same face shape, expression, age, hairstyle, clothing, framing, and background. Keep the photograph black and white. Do not beautify the face, smooth away skin texture, invent jewelry, or replace damaged text with new words.
Correct fading without inventing a new color scheme
Correct the faded and yellowed appearance of this photo. Balance exposure and restore restrained, natural contrast. Preserve recognizable facial details and clothing patterns. Where the original color is ambiguous, keep the adjustment conservative rather than adding highly saturated colors.
Improve a soft scan without plastic skin
Make this soft scanned photograph easier to read with gentle sharpening and noise reduction. Preserve natural grain, face proportions, hairline, and age. Keep the background and composition unchanged. Do not invent fine text or reshape the eyes, mouth, or nose.
After the first result, request one correction at a time: “Keep everything else unchanged; restore the original hairline.” The reference-image consistency workflow explains why the same source image matters when identity must stay recognizable.

There are even more interesting ways to use Nano Banana, such as AI face swapping, outfit changes, cosplay ，3D AI Figurine，and altering a character’s pose.It can even be 用于创建产品设计图像.
What to check at full size
| 地区 | Keep the result when | Try another edit when |
|---|---|---|
| 面孔 | The expression, age and face proportions remain recognizable. | Eyes, teeth, hairline or face shape change. |
| Text and small objects | Original marks stay legible or honestly unresolved. | New letters, jewelry or objects appear. |
| Texture | Grain and fine texture remain believable. | Skin looks waxy or edges develop halos. |
| Color | The treatment is restrained and consistent with any references. | Colors are vivid but contradict known clothing or surroundings. |
Compare the original and output at the same magnification. An attractive thumbnail can hide a changed eye or invented lettering. For a family archive, keep the scan and the edited version together and label the colorized copy separately.

常见问题
Can Nano Banana restore damaged old photos?
It can repair visible scratches, fading, and some scan defects through image editing. Results vary with the source; compare faces, small objects, and text before accepting the repair.
Which Nano Banana model should I choose?
Nano Banana 2 and Nano Banana Pro are available in the checked GlobalGPT image model list. Start with one model and the original scan, then compare a second model only if the first changes important details.
How do I stop the restored face from changing?
Use the original image as the reference, ask to preserve age and facial proportions, and request damage repair without beautification. If the face changes, return to the original and narrow the edit.
Can I restore a black-and-white photo without colorizing it?
Yes. State that the result must stay black and white, with its original contrast and grain. Colorization is a separate creative choice and is not required to repair scratches or fading.
Does AI recover the true historical colors?
No. Without reliable color references, the model produces plausible colors rather than verified historical colors. Keep a monochrome repair when archival accuracy matters.
Can I use GlobalGPT for the restoration workflow?
Yes. Open GlobalGPT Image, choose Nano Banana 2 or Nano Banana Pro, and provide the photo with a focused editing prompt. Review the current generation cost before running the edit.
