gammaaware

Gammaaware is an umbrella term used to describe systems, technologies, or processes that recognize and explicitly account for gamma correction and the non-linear response of displays and image sensors when performing color processing. It denotes an approach that treats gamma as a first-order concern in imaging pipelines, rather than something to be ignored or left implicit.

In color management, gammaaware workflows typically operate in a linear-light color space for computations and convert to a gamma-encoded space for display. This helps preserve color relationships and tonal accuracy during editing, rendering, and tone mapping. Common display gammas, such as those approximated by sRGB around 2.2, influence how images are encoded and decoded. Color management systems and ICC profiles can guide gamma-aware pipelines to maintain consistency across devices with different characteristics.

Applications of gammaaware concepts appear in photography, video editing, game engines, and display calibration tools. Software or hardware that advertises gamma awareness often provides options to linearize input data, perform processing in a linear domain, and re-encode for display, reducing artifacts in shadows and highlights and improving cross-device fidelity.

Limitations include dependence on accurate device profiles and consistent pipeline stages. If gamma assumptions are mismatched between capture, processing, and display, artifacts or dull results can occur. As with other color-management practices, gammaaware benefits from clear documentation and integration with established color spaces and profiling standards.
