standard dynamic range (SDR)
The Standard Dynamic Range(SDR) or Low Dynamic Range(LDR) is the dynamic range that can be displayed by normal displays.
In contrast to the standard dynamic range is the high- resolution High Dynamic Range( HDR). With the HDR range, displays in Ultra- HD and Ultra- HDTV are possible. The classic standard dynamic range of analog monitors is influenced by the gamma curve of the cathode ray tube( CRT). It comprises a brightness ratio of 6 bits and 8 bits. This corresponds to 64 and 256 brightness differences, respectively. For HDR displays, it is 10 bits or 12 bits, which corresponds to a dynamic range of 1,024 and 4,096 brightness differences, respectively.
