"Ansel Adams' hard work in the darkroom created photographs that showed a greater range of light than what could be captured in a single camera shot. What if modern digital cameras and displays could capture, reproduce, and manipulate a far greater range of light, much like what our eyes can actually see? High Dynamic Range Imaging is the first book to describe this exciting new field that is transforming the media and entertainment industries. Hollywood is just starting to use HDR cameras that capture far more information than traditional cameras. Soon HDR methods will replace many familiar techniques, such as the ""blue screen"" used widely in television and movies, and will allow actors to be digitally inserted into scenes while making it impossible to tell that this has been done. HDR display devices will become available, eventually at the consumer level, allowing the display of HDR video that is absolutely stunning, superior even in comparison to HDTV, like the difference between a photo from a pocket camera and an Adams' print. This book covers all the areas of HDR, including capture devices, display devices, file formats, dynamic range reduction, and image-based lighting. Written by the leading researchers in the field, it will explain and define this new technology for anyone who works with images, whether it is in film, video, photography, computer graphics, or lighting design."

cience. In the 1930s... Mannes and Godowsky invented what became known as Kodachrome and the world of color photography was forever changed. We are now on the cusp of a change of similar magnitude and the catalyst is not color, nor even digital—it is HDR."—from the foreword by Mark D.

Erik Reinhard is assistant professor at the University of Central Florida and has an interest in the fields of visual perception and parallel graphics. He has a BS and a TWAIO diploma in computer science from Delft University of Technology and a PhD in computer science from the University of Bristol. He was a post-doctoral researcher at the University of Utah. He is founder and co-editor-in-chief of the journal ACM Transactions on Applied Perception, and guest editor of a special issue on Parallel Graphics and Visualisation for the journal Parallel Computing (March 2003). He is also co-editor of Practical Parallel Rendering (A K Peters, 2002). His current interests are in visual perception and its application to computer graphics problems such as tone reproduction and color correction. He is also active in parallel rendering.Greg Ward is a leader in high dynamic range imaging and developed his first HDR image file format in 1986 for his RADIANCE lighting simulation system. Since then he has developed the LogLuv TIFF HDR image format and authored the Macintosh application Photosphere, the first HDR image-browsing program. More recently he has been involved with Sunnybrook Technologies' HDR display developments, which employ dual modulators to show colors 30 times as bright and ten times as dark as conventional monitors. He has worked in the computer graphics research community for over 20 years, and has developed rendering algorithms, reflectance models and measurement systems, tone reproduction operators, HDR image processing techniques, and photo printer calibration methods. His past employers include the Lawrence Berkeley National Laboratory, EPFL Switzerland, SGI, Shutterfly, and Exponent. Greg holds a BA in physics from the University of California, Berkeley, and a master's in computer science from San Francisco State University. He is currently working as an independent consultant in Albany, California (www.anyhere.com).Sumanta Pattanaik is an associate professor in the computer science department of University of Central Florida. From 1995 to 2001 he was a research associate in the program of computer graphics of Cornell University. Prior to that he was a post-doctoral researcher in IRISA/INRIA, France. His main fields of research are realistic image synthesis, mixed reality, and digital imaging. His research focuses on real-time rendering for virtual and mixed reality environments, the application of visual perception for efficient lighting computation and accurate display. He is the category editor of ACM Computing Reviews for the computer graphics area.Paul Debevec received his PhD from UC Berkeley where he worked with C.J. Taylor and Jitendra Malik to produce Facade, an early image-based modeling and rendering system for creating photoreal architectural models from still photographs. His work with high dynamic range imagery (HDRI) and image-based lighting has been incorporated into commercial rendering systems such as LightWave and RenderMan and has helped influence recent advancements in dynamic range in graphics hardware. The technology used in Debevec’s short films at the SIGGRAPH Electronic Theater including The Campanile Movie, Rendering with Natural Light, and Fiat Lux, has contributed to the visual effects in films including The Matrix, X-Men, and The Time Machine. In 2001 he received ACM SIGGRAPH’s Significant New Researcher award and in 2002 was named one of the world’s top 100 young innovators by MIT’s Technology Review magazine for his work to develop the Light Stage. Today he leads the computer graphics laboratory at USC’s Institute for Creative Technologies and is a research assistant professor in USC’s computer science department.
