ST 2115:2019 - SMPTE Standard - Free Scale Gamut and Free Scale Log Characteristics of Camera Signals

This standard specifies the Free Scale Gamut (FS-Gamut) and the Free Scale logarithmic transfer characteristics (FS-Log) for camera signals. The FS-Gamut consists of chromaticity coordinates of red, green, and blue primaries and a white point. The FS-Gamut and FS-Log are specified in accordance with SMPTE ST 2048-1, in which these are originally specified for digital cinematography production. — This standard also specifies names for specific sets of parameter values for FS-Gamut and FS-Log, and associated transfer characteristics for professional cameras that make use of FS-Gamut and FS-Log.
