如果您使用的是 Gemini Nano Banana，您的结果很大程度上取决于您如何编写提示。

大多数人只是输入一长串描述，然后希望获得最佳效果。

但有一种更智能的方法：JSON 提示。

为什么选择 JSON？因为它简洁。

它将您的想法组织成小方框。

您无需将所有内容都堆放在一行复杂的代码中，而是将其拆分开来。

模型能够更好地理解它，从而获得更清晰、更锐利的图像。

## 1、从基础开始

JSON 提示符有一个简单的框架：

```
{
  "style": {},
  "technical": {},
  "materials": {},
  "environment": {},
  "composition": {},
  "quality": {}
}
```

把它想象成你空的购物车。你会逐一往里面填满细节。

## 2、风格至上

这很简单：你想要什么样的外观？你想要电影风格、纪录片风格还是照片写实风格？

```
"style": {
  "primary": "photorealistic",
  "rendering_quality": "high-resolution",
  "lighting": "natural"
}
```

这句话的意思基本上是：让它看起来真实、清晰、光线自然。

## 3、添加科技元素

假设你拿着一台相机。景深、光圈、曝光——诸如此类。

```
"technical": {
  "camera_settings": {
    "depth_of_field": "shallow",
    "focal_length": "85mm",
    "aperture": "f/1.8"
  },
  "resolution": "professional quality"
}
```

无需过多考虑。只需像照片一样设置即可。

## 4、材质 = 真实纹理

这部分让物体感觉真实。皮肤有毛孔，织物有缝线，表面有划痕。

```
"materials": {
  "skin": "pores, natural imperfections",
  "fabric": "thread patterns, realistic drape"
}
```

这就是假娃娃脸和真人脸的区别。

## 5、设置场景

现在为你的图像添加环境。时间、季节、氛围。

```
"environment": {
  "time_season": "autumn sunset",
  "atmosphere": "light haze"
}
```

 正是这些细微的点缀让图像有了生命力。

## 6、别忘了构图

如果你见过构图糟糕的照片，你就会明白为什么构图很重要。

```
"composition": {
  "perspective": "natural human vision",
  "framing": "rule of thirds"
}
```

简单来说，告诉Gemini：不要切掉头部，并遵循摄影基本原则。

## 7、质量检查

最后一件事——告诉它你想要什么，以及应该避免什么。

```
"quality": {
  "include": ["hyperrealistic", "natural lighting"],
  "avoid": ["oversaturated colors", "digital artifacts"]
}
```

这就像你的“该做和不该做”清单。

## 8、完整示例

将所有内容组合起来，如下所示：

```
{
  "CORE_STRUCTURE": {
    "organization": "Organize image prompts into logical JSON sections that build systematically",
    "syntax": "Use proper syntax with correct brackets, commas, and quotation marks",
    "visual_elements": "Separate visual elements into distinct objects for precise control",
    "validation": "Validate JSON structure before submitting to avoid errors"
  },
  "STYLE_DEFINITION": {
    "primary_style": ["photorealistic", "cinematic", "documentary"],
    "rendering_quality": ["hyperrealistic", "detailed", "high-resolution"],
    "surface_textures": ["authentic material properties", "natural wear patterns"],
    "lighting": ["natural", "studio quality", "dramatic", "soft ambient"]
  },
  "TECHNICAL_SPECIFICATIONS": {
    "camera_settings": ["depth of field", "focal length", "aperture effects", "exposure"],
    "resolution": ["high definition minimum", "professional quality"],
    "rendering": ["anti-aliasing", "noise levels", "color depth standards"],
    "physics_accuracy": ["gravity effects", "structural believability"]
  },
  "MATERIAL_PROPERTIES": {
    "skin_textures": ["pores", "natural imperfections", "ethnic diversity"],
    "fabric_details": ["thread patterns", "realistic drape", "wear indicators"],
    "surfaces": ["scratches", "patina", "authentic oxidation", "natural irregularities"],
    "transparency": ["accurate refraction", "surface interactions"]
  },
  "ENVIRONMENTAL_FACTORS": {
    "atmospheric_conditions": ["distance haze", "weather effects", "humidity"],
    "time_season": ["lighting conditions", "seasonal elements", "temperature cues"],
    "particle_effects": ["dust", "moisture", "atmospheric depth"]
  },
  "COMPOSITION_CONTROLS": {
    "perspective": ["natural human vision", "photography composition rules"],
    "framing": ["rule of thirds", "golden ratio", "professional positioning"],
    "subject_placement": ["balanced", "aesthetically pleasing arrangement"]
  },
  "QUALITY_KEYWORDS": {
    "include": ["hyperrealistic", "photographic quality", "natural lighting", "authentic textures"],
    "avoid": ["digital artifacts", "unrealistic proportions", "oversaturated colors"],
    "reference": ["National Geographic", "professional photography standards"]
  }
}
```

你不需要写出完美的提示。只需将你的想法分解成几个部分：风格、相机、材料、环境、构图、质量。就是这样。

一旦你开始这样做，Gemini Nano Banana 就不再猜测，而是开始精准地满足你的要求。
