# 🎨 [LoRA 名称] — Cinematic Anime Backgrounds (Outdoor)
|
| 301 |
+
|
| 302 |
+
## 📄 简介
|
| 303 |
+
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。
|
| 304 |
+
**触发词(Trigger)**: `shinkaibg`
|
| 305 |
+
|
| 306 |
+
---
|
| 307 |
+
|
| 308 |
+
## 🧪 对比实验说明
|
| 309 |
+
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)。
|
| 310 |
+
|
| 311 |
+
---
|
| 312 |
+
|
| 313 |
+
## 🔁 Same Seed — Same Prompt 比较(示例)
|
| 314 |
+
**Prompt 示例:** `a quiet japanese street at sunset, cinematic lighting, painterly detail, shinkaibg`
|
| 315 |
+
|
| 316 |
+
| Prompt | Without LoRA | With LoRA |
|
| 317 |
+
|--------|--------------|----------|
|
| 318 |
+
| same seed, same prompt |  <br> *Without LoRA* |  <br> *With LoRA (`shinkaibg` applied)* |
|
| 319 |
+
|
| 320 |
+
**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)。
|
| 321 |

+
## 🏠 室内过拟合测试(Indoor Overfitting Test)
|
| 325 |
+
**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。
|
| 326 |
+
|
| 327 |
+
**Prompts 示例:**
|
| 328 |
+
- **simple:** `a cozy living room`
|
| 329 |
+
- **detailed:** `a cozy japanese-style living room with warm sunlight through window, tatami floor, shinkaibg`
|
| 330 |
+
|
| 331 |
+
| Type | Without LoRA | With LoRA |
|
| 332 |
+
|------|--------------|----------|
|
| 333 |
+
| Simple prompt |  <br> *No LoRA* |  <br> *With LoRA — 注意可能出现室外光效 / 窗外景观* |
|
| 334 |
+
| Detailed prompt |  <br> *No LoRA* |  <br> *With LoRA — 需更详尽描述以避免户外化 bias* |
|
| 335 |
+
|
| 336 |
+
**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。
