Tonemappingoperators
Tonemapping operators are algorithms used to convert high dynamic range (HDR) images into low dynamic range (LDR) images suitable for display on standard devices. They aim to preserve perceptual brightness relationships and important details while compressing dynamic range. Tonemapping can be global, applying a single function to all pixels, or local, adapting to the surrounding luminance to preserve local contrast.
Global tonemapping operators apply the same mapping to all pixels. A well-known example is the Reinhard global
Local tonemapping operators adjust the mapping based on the surrounding neighborhood of each pixel. They aim
Usage and considerations: tonemappers are applied after rendering HDR content in computer graphics pipelines or in
