## Content

作者：Dr. Stochastic Parrot

状态：内容收口候选稿。18 个编号章节、48 幅可复现技术图、62 道练习及逐题答案
已经闭环；仍可在获得真实器材实验数据后增加案例，但不再依赖这些数据才能完成主线。

这本书不从品牌和器材型号出发，而从一次曝光怎样形成一幅图像出发。主线是

$$
\text{场景辐亮度}
\longrightarrow \text{镜头像面曝光}
\longrightarrow \text{光电子}
\longrightarrow \text{读出码值}
\longrightarrow \text{RAW/Log/RGB}
\longrightarrow \text{显示或印刷图像}.
$$

只有把术语放回这条链，才能判断“高 ISO 更亮”“Log 损失画质”“像素越大越
好”“堆栈传感器噪声更大”“萤石一定比玻璃锐”“MTF 曲线代表一切”究竟在哪些
条件下成立。全书默认读者会高中数学；微积分、复数、Fourier 变换和概率论在使用
处给出必要推导，较系统的工具集中在附录 A。

符号与约定、资料来源、逐章注释、习题答案和术语索引均已收入本书目录；技术图为机制图或解析曲线，不冒充具体器材实测。

## 范围边界

本书讨论摄影和电影摄影所需的成像物理、电子学、计算成像与镜头分析。完整半导体
器件工艺、镜头优化软件、感知色貌模型、压缩编码器实现和摄影艺术史属于外部学科，
只在主线需要处建立接口。本书不替某一品牌评定器材，也不把实验室单一指标等同于
照片价值。
