Tone mapping methods, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect.

Tone mapping, in the context of graphics rendering, is a technique used to map colors from high dynamic range ( in which lighting calculations are performed ) to a lower dynamic range that matches the capabilities of the desired display device.

Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another in order to approximate the appearance of high dynamic range images in a medium that has a more limited dynamic range.
