15 HDR

High Dynamic Range. HDR is used in many aspects of technology. It can be used in television, photography (iPhone camera), audio, and more. From a visual standpoint, HDR usually refers an image that was created from composite images and utilizes tone-mapping to create a richer, more accurate image. This can result in blacker blacks and brighter whites.

In audio, HDR refers to a higher dynamic of audio ranges and can be used to restore original audio.
