这些用于提升图片质量的 Gemini 提示词,针对的都是真实照片中常见的问题:对焦不实、曝光不佳、数码噪点、细节不足,以及干扰视线的取景方式。上传图片后,粘贴最接近需求的提示词;仅在必要时修改方括号中的内容。最好的修图通常具体而克制,因此要明确告诉 Gemini 哪些内容必须保持不变。

如何使用这些图片优化提示词

先上传原始图片,而不是它的截图。然后说明主要问题、图片用途,以及希望 Gemini 保留的内容——尤其是人脸、文字、Logo、产品形状或某种特定氛围。

一个实用的提示词包含四个部分:

  1. 你希望进行的修正。
  2. 需要重点保护的重要细节。
  3. 想要的最终效果或风格。
  4. 防止过度编辑的限制条件。

例如,“提高锐度”过于笼统;“锐化鸟的眼睛和羽毛边缘,同时保持背景柔和并保留自然的羽毛纹理”,则为编辑划定了清晰边界。

用于模糊或柔焦图片的提示词

1. 修复整体发软

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.

当整张照片看起来略微发软、但主体仍然清晰可辨时,可使用这条提示词。

2. 锐化人像,同时不改变人物

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.

人像编辑常常失败,是因为把锐化同等地应用到所有区域。点明重点区域,有助于避免皮肤看起来干硬脆裂。

3. 改善存在运动模糊的主体

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.

将方括号中的文字替换为“runner”和“face and shoes”等具体内容。如果模糊很严重,应要求得到可信的改善,而不是完美重建。

用于曝光与光线的提示词

4. 提亮曝光不足的照片

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.

这条提示词很适合室内照片、逆光主体,以及在昏暗环境中拍摄的图片。

5. 修复高光过强的照片

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.

适用于明亮天空、白色衣物、反光产品,或被直射阳光照到的面部。

6. 校正室内混合光源

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、办公室和夜间活动中常见混合光源。如果能判断出不需要的偏色来自哪里,请在提示词中说明。

用于噪点、压缩与低分辨率图片的提示词

7. 降低弱光噪点

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.

降噪应当保守。没有纹理的干净图片,可能比原图看起来更糟。

8. 清理压缩图片

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.

这适合反复保存过的图片、从即时通讯应用下载的图片,或从旧网页上传内容中提取的图片。

9. 为更大尺寸展示准备小图片

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.

请说明最终用途,因为大尺寸印刷所需的细节与平滑度平衡,和小尺寸社交媒体图片并不相同。

用于细节与纹理的提示词

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.

对于电商图片,准确性比戏剧化增强更重要。编辑后务必检查 Logo、标签、缝线和包装。

11. 自然改善风景纹理

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.

只选择真正需要处理的纹理。要求所有区域都增强细节,会让风景看起来修饰过度。

12. 恢复老照片细节

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,请要求进行谨慎修复。图片工具不应被视为证明原始内容的依据。

用于构图与清理的提示词

13. 改善取景,同时不改变场景

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].

编辑前先说明目标格式。适合个人主页帖文的裁切,在竖版布局中可能会截掉主体。

14. 移除背景中的干扰元素

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.

请精确说明哪些内容需要消失。“移除杂物”可能会带来超出预期的更大范围改动。

15. 制作精修后的最终图片

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.

在修复具体问题之后,可将它作为最后一道处理,而不是将其作为处理困难图片的第一条提示词。

一个完整的提示词示例

假设你有一张昏暗餐厅里拍摄的人像,画面偏黄且细节柔和。与其让 Gemini “make it HD”,不如使用下面这条提示词:

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.

这会告诉 Gemini 应该修复什么、保护什么,以及应避免哪种效果。如果第一次结果太亮,可以继续补充:“Keep the corrected skin tone, but restore slightly deeper shadows and preserve more of the original warm ambience.”

常见提示词错误

除非你想得到范围宽泛且难以预测的编辑结果,否则不要要求“maximum quality”。请直接说出你看得见的问题。

不要要求源图中根本看不见的细节。比起“reveal the exact text on the distant sign”,更好的要求是“restore plausible clarity”。

此外,要明确保留关键元素。对于包含人物、产品或可读文字的图片,每一条重要编辑提示词中都应写明这一点。

常见问题

Gemini 能把模糊照片变得完全清晰吗?

不一定。轻微发虚通常可以改善,但严重的运动模糊、失焦或尺寸很小的原图,可能并不包含足以准确恢复的真实细节。应要求自然可信的优化,而不是精确还原缺失的信息。

用于暗图的最佳 Gemini 提示词是什么?

先从提示词 4 开始,再补充说明必须保持清晰可见的具体主体。如果图片存在偏黄或偏蓝的光线,可结合提示词 6 中关于白平衡的说明。

如何防止图片增强工具改变人脸?

明确说明人物身份、表情、年龄、肤色和面部结构必须保持不变。将锐化限制在眼睛和头发等部位,并要求 Gemini 不要过度磨皮。

这些提示词可以用于产品图片吗?

可以。提示词 8、9 和 10 特别适合产品图片。务必说明品牌标识、标签、颜色、尺寸和设计细节都必须保持准确。

结语

最有效的 Gemini 图片质量提升提示词,会聚焦一个可见问题,并为编辑设定清晰限制。先从最接近需求的模板开始,以原始尺寸检查结果,然后提出一项有针对性的后续修改,而不是从头重做整张图片。
