# 🎨 [LoRA 名称] — Cinematic Anime Backgrounds (Outdoor)

## 📄 简介
此 LoRA 专注于生成**户外电影感（cinematic）动漫背景**：夕阳 / 金色时刻、画面感强的云与光线、宁静的日本郊区街景。  
**触发词（Trigger）**: `shinkaibg`

---

## 🧪 对比实验说明
展示相同 seed、相同 prompt 在 **未应用 LoRA / 应用 LoRA** 下的差异；以及室内提示的过拟合测试（模型偏向户外氛围）。

---

## 🔁 Same Seed — Same Prompt 比较（示例）
**Prompt 示例：** `a quiet japanese street at sunset, cinematic lighting, painterly detail, shinkaibg`

| Prompt | Without LoRA | With LoRA |
|--------|--------------|----------|
| same seed, same prompt | ![no_lora_street](images/same_seed_prompt_without_lora.png) <br> *Without LoRA* | ![with_lora_street](images/same_seed_prompt_with_lora.png) <br> *With LoRA (`shinkaibg` applied)* |

**说明：** LoRA 版本通常会加入更柔和的光线过渡、更丰富的天空细节与更强的电影感（色彩与景深）。

---

## 🏠 室内过拟合测试（Indoor Overfitting Test）
**测试说明：** 使用相同 seed，四张图展示 `simple prompt` / `detailed prompt`，并比较有无 LoRA 的输出差异。

**Prompts 示例：**
- **simple:** `a cozy living room`
- **detailed:** `a cozy japanese-style living room with warm sunlight through window, tatami floor, shinkaibg`

| Type | Without LoRA | With LoRA |
|------|--------------|----------|
| Simple prompt | ![simple_no](images/indoor_simple_without_lora.png) <br> *No LoRA* | ![simple_yes](images/indoor_simple_with_lora.png) <br> *With LoRA — 注意可能出现室外光效 / 窗外景观* |
| Detailed prompt | ![detailed_no](images/indoor_detailed_without_lora.png) <br> *No LoRA* | ![detailed_yes](images/indoor_detailed_with_lora.png) <br> *With LoRA — 需更详尽描述以避免户外化 bias* |

**观察：** 若只使用简单室内 prompt，模型往往会“套用”户外 / 日落光线（显示过拟合）。详细 prompt 能降低但不完全消除该现象。

---

## ⚙️ 推荐参数（示例）
- LoRA 权重 (strength): `0.7` - `0.9`  
- CFG Scale: `7` - `9`  
- Sampler: `DPM++ 2M Karras`（示例）  
- Resolution: `1024×1024`  

---

## 🧾 标签与数据集信息
- 数据集规模：`~[填数字]` 张户外风景图  
- 主要风格标签：`shinkaibg`, `cinematic`, `sunset`, `painterly`  
- 注意：训练集中强烈偏向户外场景，导致 indoor prompt bias（详见上方测试）
