15 条 Gemini 提升画质提示词：修复模糊、光线差和细节不足
15 条复制即用的 Gemini 提升画质提示词，专治照片模糊、光线差、噪点多、细节不足和构图杂乱，修图、画质增强、老照片修复都能找到对应的写法。
这些 Gemini 提升画质提示词，针对的都是真实照片里的常见毛病：对焦发虚、曝光不对、数码噪点、细节不足、构图杂乱。上传图片，粘贴最接近的一条提示词，方括号里的内容有需要再改。好的修图通常具体而克制，所以一定要告诉 Gemini 哪些地方不能动。
这些画质提示词怎么用
先上传原图，别用截图。然后说明主要问题、图片用途，以及 Gemini 必须保留的东西——尤其是人脸、文字、Logo、产品形状或某种特定的氛围。
一条好用的提示词包含四部分：
- 你想要的修正。
- 需要保护的重要细节。
- 想要的成片效果或风格。
- 防止修过头的限制条件。
例如，“提高锐度”太笼统；“锐化鸟的眼睛和羽毛边缘，背景保持柔和，保留自然的羽毛纹理”，就给这次修图划出了清楚的边界。
模糊、发虚图片的提示词
1. 修复整体发虚
Improve the sharpness and perceived clarity of this image. Restore clean edge definition in the main subject without creating harsh outlines, halos, or an artificial over-sharpened look. Preserve the original colors, composition, and natural texture.整张照片略微发虚、但主体还能认出来时，用这一条。
2. 人像锐化，人不走样
Refine this portrait by improving focus around the eyes, eyelashes, hairline, and facial features. Keep the person’s identity, age, skin tone, expression, and natural skin texture unchanged. Do not smooth the skin excessively or add makeup-like detail.人像修图常常翻车，是因为锐化一视同仁地加在了所有地方。点名需要锐化的部位，皮肤就不容易显得干涩粗糙。
3. 改善主体的运动模糊
Reduce the appearance of motion blur on the [subject], especially around [important area]. Reconstruct believable detail only where supported by the image. Keep the background motion and original scene intact, and avoid inventing objects, letters, or facial features.把方括号里的内容换成具体描述，比如 “runner”（跑步的人）和 “face and shoes”（脸和鞋）。如果模糊很严重，就只要求可信的改善，别指望完美还原。
曝光与光线提示词
4. 提亮欠曝的照片
Correct this underexposed image by lifting shadows and midtones while protecting highlights. Reveal detail in dark areas without making the photo look washed out or flat. Keep black areas believable and preserve the original atmosphere.这条很适合室内照片、逆光的主体，以及暗光下拍的图。
5. 挽救高光过曝的照片
Balance the lighting in this image by reducing overly bright highlight areas and restoring a natural tonal range. Preserve bright reflective surfaces where appropriate, but recover visible detail where possible. Keep the image realistic and avoid a dull gray result.适用于明亮的天空、白色衣服、反光的产品，或者被阳光直射的脸。
6. 校正室内混合光
Correct the mixed lighting in this photo. Neutralize unwanted color casts from [warm indoor lights / window light / colored lights] while keeping skin tones and important object colors accurate. Create one coherent, natural-looking white balance without removing the scene’s mood.餐厅、办公室和晚间活动里经常是混合光源。如果能判断出多余的偏色来自哪里，就在提示词里写出来。
噪点、压缩和低分辨率图片的提示词
7. 暗光降噪
Reduce digital noise and color speckling in this image, especially in shadow areas and smooth backgrounds. Retain fine texture in hair, fabric, leaves, and other detailed surfaces. Do not make the image waxy, plastic-looking, or overly smooth.降噪要保守。一张干干净净却没有一点纹理的图，可能还不如原图。
8. 清理压缩痕迹
Improve this compressed image by reducing blockiness, ringing, banding, and JPEG-like artifacts. Restore smooth color transitions and cleaner edges while preserving real details, text, logos, and the original proportions of all objects.适合反复保存过的图、从聊天软件里下载的图，或者从老网页上存下来的图。
9. 小图放大，用于大尺寸展示
Increase the usable resolution of this image for a [website banner / print / social post]. Preserve the exact composition and subject proportions. Add only plausible detail supported by the original image, with clean edges and natural texture; do not invent text or change identifiable features.一定要写明最终用途：大幅印刷和小尺寸社交配图，对细节和平滑度的取舍并不一样。
细节与质感提示词
10. 突出产品细节
Enhance the visible detail of this product photo. Improve clarity in material texture, edges, and small design features while keeping the product’s shape, color, branding, and proportions exactly accurate. Use clean, realistic studio-style detail without changing the product design.电商图片里，准确比效果惊艳更重要。修完一定要检查 Logo、标签、缝线和包装。
11. 自然增强风景质感
Enhance natural detail in this landscape, with careful refinement of [rocks / foliage / water / clouds]. Keep the lighting direction, weather, color palette, and depth of the original scene. Avoid crunchy sharpening, exaggerated HDR contrast, or repetitive artificial texture.只挑真正需要处理的纹理。要求处处都加细节，风景反而会显得修图痕迹很重。
12. 老照片修复
Carefully restore this old photograph. Reduce visible damage, fading, dust, and scratches while preserving the original person, clothing, objects, era-appropriate appearance, and photographic character. Do not modernize the scene or invent missing historical details.如果人脸或文件损坏严重，就要求谨慎修复。别把图像工具修出来的结果，当作原本就是这样的证据。
构图与清理提示词
13. 优化构图，不改场景
Improve the composition of this image by creating a stronger frame around the main subject. Crop or extend the canvas only when needed, while preserving the subject’s scale, pose, and visual balance. Keep the result suitable for a [square post / landscape banner / vertical story].修图前先说明目标画幅。适合主页帖子的裁切，放到竖版布局里可能会切掉主体。
14. 去掉背景里的干扰物
Clean up distracting background elements such as [object or area]. Keep the main subject completely unchanged, including its edges, shadows, reflections, and contact with the environment. Rebuild the background so it remains consistent with the original lighting and perspective.要去掉的东西写得越精确越好。只写“移除杂物”，改动范围可能比你预想的大得多。
15. 最后整体精修
Give this image a careful professional-quality finish. Correct exposure, white balance, noise, minor distractions, and local sharpness only where needed. Preserve the original subject, composition, color character, and realistic texture. The result should look naturally well-photographed, not heavily filtered.这条适合在修完具体问题之后做最后的收尾；碰到难处理的图，别一上来就用这条。
完整提示词示例
假设你有一张在昏暗餐厅里拍的人像，画面偏黄、细节发虚。与其让 Gemini “make it HD”（弄成高清），不如用这一条：
Improve this restaurant portrait by lifting the face and clothing out of the shadows, reducing the strong yellow indoor color cast, and refining focus around the eyes and hair. Keep the person’s identity, expression, skin texture, and the warm evening atmosphere unchanged. Reduce noise in the dark background without smoothing the face or making the image look heavily edited.这条提示词告诉了 Gemini 要修什么、要保护什么、要避免哪种效果。如果第一次的结果太亮，可以接着说：“Keep the corrected skin tone, but restore slightly deeper shadows and preserve more of the original warm ambience.”（保留校正后的肤色，但把阴影压深一点，多留一些原来的暖调氛围。）
常见的提示词误区
除非你想要一次范围很大、结果难料的修改，否则别要求 “maximum quality”（最高画质）。直接点出你看得到的问题。
别要求原图里根本看不见的细节。与其写 “reveal the exact text on the distant sign”（把远处招牌上的字准确还原出来），不如写 “restore plausible clarity”（恢复合理的清晰度）。
还有，关键元素要明确要求保留。图里有人物、产品或可读文字的，每条改动较大的提示词都要写上这一点。

常见问题
Gemini 能把模糊照片变得完全清晰吗？
不一定。轻微发虚通常能改善，但严重的运动模糊、跑焦，或者原图尺寸太小，图里可能根本没有足够的真实细节可供准确还原。要求自然、可信的优化就好，别要求精确找回缺失的信息。
照片太暗，用哪条 Gemini 提示词最好？
先用提示词 4，再补上必须看清的具体主体。如果图片偏黄或偏蓝，再加上提示词 6 里关于白平衡的说明。
怎么防止画质增强工具把人脸改了？
写明人物长相、表情、年龄、肤色和脸型必须保持不变。锐化只限于眼睛、头发这类部位，并要求 Gemini 不要过度磨皮。
这些提示词能用在产品图上吗？
可以。第 10 条提示词专门用于产品图。一定要写明品牌标识、标签、颜色、尺寸和设计细节都必须保持准确。
一键拿到修复指令
本文的修复用语都打包进了免费的修图提示词挑选器：勾选症状（模糊、皮肤塑料感、手部变形……），就能复制一段合并好的修复指令。画面比例不对是另一类问题，用画面比例画布生成器解决。
结语
最有效的 Gemini 提升画质提示词，一次只盯一个看得见的问题，并给修改划清边界。先挑最接近的模板，放大到原尺寸检查结果，再针对性地追加一条修改要求，而不是把整张图推倒重来。
