High Dynamic Range (HDR) is a set of technologies designed to represent the visual world with greater fidelity by capturing and displaying a wider range of light intensity and colors compared to Standard Dynamic Range (SDR). HDR allows for deeper colors and brighter highlights, enhancing the visual experience on compatible displays.
At WWDC, Apple introduced several sessions related to HDR:
-
