This work recounts the research on capturing real-life scenes, calculating appearances, and rendering sensations on film and other limited dynamic-range media. It describes the first patents, a hardware display used in Land's Ives Medal Address in 1968, the first computer simulations using 20×24 pixel arrays, psychophysical experiments and computational models of color constancy and dynamic range compression, and the Frankle-McCann computationally efficient retinex image processing of 512×512 images. It includes several modifications of the original approach, including recent models of human vision and gamut-mapping applications. This work emphasizes the need for parallel studies of psychophysical measurements of human vision and computational algorithms used in commercial imaging systems.
