Tone Mapping Tone mapping is a digital image processing technique used to enhance the dynamic range and tonal range of high dynamic range (HDR) images for display on standard dynamic range (SDR) devices, such as computer monitors and print media. HDR images contain a wider range of luminance values than traditional images, capturing details in both the highlights and shadows of a scene.
Tone mapping algorithms compress and remap the tonal values of HDR images to fit within the limited dynamic range of SDR displays while preserving as much detail and contrast as possible. Tone mapping techniques include global tone mapping, local tone mapping, and adaptive tone mapping, each of which adjusts the tonal values of the image to optimize its visual appearance and ensure that details are visible across the entire tonal range. |
