🎨 [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	Without LoRA	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	No LoRA	With LoRA — 注意可能出现室外光效 / 窗外景观
Detailed prompt	No LoRA	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。
