What does HDR refer to in photography? Photography HDR
HDR is the abbreviation of High Dynamic Range in English, which is a post-processing technology. Dynamic range refers to the relative ratio of the highest and lowest values ??of the electrical signal, which is reflected in the photos as the details that can be displayed in the highlight and dark areas. The larger the dynamic range, the richer the levels. In order to get the HDR picture effect, it is not enough to take one photo. You need to take a series of photos with different exposure values ??and combine them into a high dynamic range photo through software.
