HDR Imaging
John J. McCann, Alessandro Rizzi · 2011
This chapter lists many disciplines that help us understand High-Dynamic-Range (HDR) imaging. It describes the work of artists, scientists, and engineers that have developed techniques to capture HDR scenes and render them in a wide variety of media. The chapter points out the difference between traditional physics, in which light is always measured at a pixel, and human vision, in which spatial image content is important. In vision it is the relationship between pixels, rather than their individual values, that controls appearance. A section reviews the many Color Mondrian experiments using complex scenes made of arbitrary, unrecognizable shapes. Finally, the chapter describes and compares a large variety of HDR algorithms.
