Invited Colorlab Workshop #7/2008: Dynamic range of light, contrast and perception in digital images, organized by the Norwegian Color Research Laboratory, Gjøvik University College. In natural and artificial environments light has an extremely high variance of its physical characteristics. It varies very much in spectral composition, intensity, geometrical diffusion or reflection, together with the presence of transmission and refraction phenomena as well. What our vision system or a camera captures is always a mixture of these characteristics of the light, distorted by the geometrical characteristic of the scene and the reflectance and diffusive properties of all the materials that compose it. Among all these characteristics, the workshop aims at focusing on the dynamic range of light that the digital imaging field quite recently started to investigate. At the very beginning it has been considered just as a numerical extension of the digit range, but more complex phenomena have to be taken into account to understand end explore this phenomenon and to foster related research. This workshop aimed to propose a brief (not necessarily complete) overview on open issues, problems and possible solutions as a starting point of discussion for future direction of research.
