Abstract: The emergence of high dynamic range (HDR) content and displays requires methods for adapting content to different display capabilities. This paper addresses mastering and encoding considerations, and presents methods for adapting HDR-mastered content for viewing on displays with different capabilities and viewing environments. Specifically, HDR grading considerations and coordinated methods for dealing with reductions in highlight and shadow range are presented, along with methods for adjusting midtone brightness to compensate for reductions in dynamic range and different surround luminances. The degree to which such adaptations can and should preserve the mastered appearance are discussed. Issues in converting between standard dynamic range (BT.1886), hybrid log-gamma, and perceptual quantization EOTFs are also addressed. The conclusions note the importance of creating high quality, well-defined masters on well-behaved displays in appropriate environments and some problems that can arise when displays aggressively remap images. Recommendations include mastering for a target HDR display, methods for adapting content for different receiving displays, and coordination of display and surround luminances to preserve the mastered appearance.
