The field of High Dynamic Range imaging or ‘HDR’ was coined over 20 years ago. Over time, various building blocks have been designed that are suitable to form perceptually correct, artistically compelling and technologically efficient HDR imaging systems. Now, as those technologies are in the process of being implemented in mainstream devices, it is important keep track of several key perceptual and technological concepts in order to avoid pitfalls that can impact image fidelity when processing, transmitting, and displaying HDR imagery.

Timo Kunkel is a senior color and imaging researcher at Dolby Labs, Inc. in Sunnyvale, CA. His main areas of research are perception based color models, high dynamic range imaging, advanced display technologies and psychophysics. Before moving to the US, he worked for Dolby in Vancouver, Canada, investigating the dynamic range limits of the human visual system and on creating novel color appearance models. Over the last twelve years he also worked as architecture and landscape photographer for clients in Europe and the US as well as head of pre-press imaging and co-founder of a German children’s book publisher. He received his PhD in Computer Science from the University of Bristol, UK and a MSc in Physical Geosciences from the University of Freiburg in Germany.
