Abstract: There is a need to exchange high dynamic range wide gamut moving images that embody creative intent. Simple definitions using CIE 1931 chromaticity having extended gamut may not suffice. It may be desirable to extend gamut beyond P3, even for material mastered using P3 displays and projectors. It is also clearly useful to master to a dynamic range that may exceed a given mastering device. Reduced gamut and dynamic range used temporarily during mastering provides a means of checking image integrity outside of device gamut and range limits. However, additional information about mastering emission spectra is also useful, yet is difficult to interpret as gamut widens further. This paper seeks to explore these issues, and to propose approaches to defining a High Dynamic Range (HDR) Wide Color Gamut (WCG) Intermediate that can be exchanged with increased confidence with respect to creative mastered intent.
