HPA 2018: Panel Discusses Hurdles to Mass Adoption of HDR
In the ongoing journey to integrate high dynamic range (HDR) into U.S. movie theaters and homes, a panel at this week’s HPA Tech Retreat in Palm Desert, California explored the topic from several angles. Everyone knows that HDR is much more than a single format: HDR10, HDR10+, Dolby Vision, HLG (hybrid log gamma) all compete in the marketplace. But Pat Griffis, Dolby Laboratories vice president technology in the office of the CTO and a SMPTE fellow, wanted to clarify the basic definition of HDR as more accurately seen as color volume.
“Color volume is the 3D palette of all the colors that can be reproduced at all allowable intensities,” explained Griffis. “What’s missing [in our discussion of HDR] is how bright each of the colors are, and that’s where the three dimensional color volume comes in. HDR has taken the lid off Pandora’s box and made many more colors available, not just contrast but brightness.”
