Tone Mapping

A tone mapping operator is a tool for displaying a High Dynamic Range image (with no intensity limitation) on a Low Dynamic Range screen (with an intensity limited to 1) which is unable to manage the range of light intensities present in the image. Using a tone mapping operator to display HDR images can reveal details otherwise invisible. However, tone mapping operators can change the appearance of the colors, shadows and lights.

The three tone mapping effects are detailed below.
