In the design of a high dynamic range (HDR) ecosystem including the key stages of image capture, image synthesis, post-production, encoding, transmission, decoding, and display, the foundation relied on visual system models and new perceptual experiments. For example, this design took a future-proof approach by basing the system limits on the visual system as opposed to existing or near-term expectant display hardware. The substantially increased luminance ranges of HDR require more careful consideration of light adaptation, the role of diffuse and specular reflections, interactions of emissives with the color volume, quantization nonlinearities as well as other factors that existing video standards (i.e., rec709) never had to consider. This talk will give an overview of these applied visual system designs, as well as the new creative opportunities opened up by this HDR ecosystem.
