其实只需要记住一个大逻辑：

SDR 显示能呈现的图像，大概是能对应纸质印刷品（包括各种画）能够呈现的，相对于现实世界而言有限的光影关系的。

HDR 显示的出现，本质上源于技术进步带来的，数字传感器记录能力的提高，以及显示设备亮度、对比度呈现能力大幅提升，从而提供了远超纸质介质的呈现能力。因此相应出现的标准。

PS：胶片（特别是负片）本质上也具备 HDR 记录能力。

HDR 标准里的引入了【参考白 Reference White / 漫反射白 Diffuse White / 纸面白 Paper White（三个词本质都是同一个意思）】的概念，对应的就是这一层。

所有基于HDR规格制作渲染的图像，必然都是为电子化发光显示设备的图像消费场合准备的。

正是由于这一点，图片领域 SDR 和 HDR 需求必然且长期处于并存状态（除非你彻底淘汰纸媒和印刷出品）。所以才会催生出 ISO 22028-5，以及基于 Gain Map 实现对于 SDR、HDR 双版本管理的 ISO 21496-1 标准。
