+# AI-PP3 处理挑战分析
+
+本项目将基于 Gemini 2.5 Pro 生成的 AI 自动化 RawTherapee 处理配置文件（PP3）与 [RawTherapee 处理挑战](https://rawpedia.rawtherapee.com/Rawtherapee_Processing_Challenge_feedback) 中的人工编辑结果进行对比。
+
+## 项目结构
+
+每个示例文件夹包含以下内容：
+
+- 挑战提供的原始 RAW 文件
+- 基础 PP3 文件（通过直接打开 RAW 文件后未做任何调整即保存生成）
+- `ai.pp3`（AI 生成的处理配置文件）
+- `ai.jpg`（应用 AI PP3 后的处理结果）
+- `ai.sh`（通过 OpenRouter 调用 Gemini 2.5 Pro 生成 PP3 的脚本）
+
+```plaintext
+/1
+  ├── IMG_0080.CR2
+  ├── IMG_0080.CR2.pp3
+  ├── ai.pp3
+  ├── ai.jpg
+  └── ai.sh
+... （共 6 个示例文件夹）

+| DSC5286.NEF        | 轮船细节、运动模糊、低对比度          | -        |
+
+## AI 处理流程
+
+### 1. 基础 PP3 创建
+
+- 在 RawTherapee 5.9+ 中打开 RAW 文件
+- 无需任何调整直接保存为 `base.pp3`
+
+### 2. AI 配置文件生成
+
+```bash
+# 示例：/examples/1/ai.sh
+#!/bin/bash
+export OPENAI_API_KEY=your-key-here
+
+ai-pp3 IMG_0080.CR2 \
+  --provider openrouter \
+  --model google/gemini-pro-1.5 \
+  --base IMG_0080.CR2.pp3 \
+  --output ai.pp3
+```
+
+**依赖项**：
+
+- RawTherapee 5.9+
+- OpenRouter API 密钥（用于调用 Gemini 模型）
+- 基础命令行操作能力
+
+## 评估方法
+
+### 1. 技术对比
+
+```bash
+# 忽略时间戳的结构化差异
+diff -I '\<Date\>' base.pp3 ai.pp3
+
+# 参数统计
+awk -F= '/^[^#]/ {print $1}' ai.pp3 | sort | uniq -c
+```
+
+### 2. 视觉评估
+
+- RawTherapee 中并排对比
+- 直方图分析色调分布
+- 放大观察噪点模式
