Should we assume that you already know/understand what the wp article on gamma correction says? It is brief but gives a useful overview. Pieces of two sentences pasted behind the link: https://en.wikipedia.org/wiki/Gamma_correction Gamma encoding of images is used to optimize the usage of bits when encoding an image, or bandwidth used to transport an image, by taking advantage of the non-linear manner in which humans perceive light and color. ... If images are not gamma-encoded, they allocate too many bits or too much bandwidth to highlights that humans cannot differentiate, and too few bits or too little bandwidth to shadow values that humans are sensitive to and would require more bits/bandwidth to maintain the same visual quality. -- Mike Easter
