With 7 major families of workflows, 4 competing distribution formats, 5 display technologies and more on the way, it is easy to get lost in the "jungle" of HDR. This guide, the result of 4 years of research and field tests, covers the entire HDR chain from lighting to capture, post-production, encoding, delivery and display. It includes a comprehensive dictionary of terms related to HDR - an important foundation for teams wishing to communicate and collaborate effectively in this emerging medium. With examples, figures and examples, the guide avoids complicated mathematical formulas, focusing on the practical implications of successfully implementing HDR.
