The Complication Behind HDR

High Dynamic Range (HDR) was the hot topic at IBC in Amsterdam this year. But as visually exciting as HDR can be, there are a lot of checkpoints along the way that block progress and could interfere with the speed of adoption.

HDR refers to the extended range of light possible in the image. It requires that a larger range of luminance values be transmitted or stored, and that a larger range of luminance be displayed than found in standard range displays. A new term, HDR+, refers to the combination of HDR with wider color gamut. The DCI P3 color gamut associated with digital cinema is already larger than that available for HDTV. But larger gamuts are now possible, and best associated with higher levels of luminance, thus HDR+.
