High Dynamic Range Imaging book cover

High Dynamic Range Imaging

Acquisition, Display, and Image-Based Lighting

This landmark book is the first to describe HDRI technology in its entirety and covers a wide-range of topics, from capture devices to tone reproduction and image-based lighting. The techniques described enable you to produce images that have a dynamic range much closer to that found in the real world, leading to an unparalleled visual experience. As both an introduction to the field and an authoritative technical reference, it is essential to anyone working with images, whether in computer graphics, film, video, photography, or lighting design.

Audience
R&D Professionals in computer graphics, digital design and visualization. Visual effects artists in entertainment industry (including interactive entertainment/games). Engineering staff (i.e. coders, implementors of HDRI) at HDRI display/sensor manufacturers (e.g., Phillips, Samsung).

Reviews

  • "With the mainstream introduction of affordable LED HDTVs and computer monitors, the principles of high dynamic range imaging have gone from an academic research topic to essential knowledge. For anyone involved in software or hardware development for computer games and entertainment video, this second edition of High Dynamic Range Imaging offers everything you need and more. Highly recommended."
