Rendering High Dynamic Range (HDR) scenes on media with limiteddynamic range began in the Renaissance whereby painters, thenphotographers, learned to use low-range spatial techniques tosynthesize appearances, rather than to reproduce accurately thelight from scenes. The Art and Science of HDR Imagingpresents a unique scientific HDR approach derived fromartists' understanding of painting, emphasizing spatialinformation in electronic imaging.
Human visual appearance and reproduction rendition of the HDRworld requires spatial-image processing to overcome the veilingglare limits of optical imaging, in eyes and in cameras.Illustrated in full colour throughout, including examples offine-art paintings, HDR photography, and multiple exposure scenes;this book uses techniques to study the HDR properties of entirescenes, and measures the range of light of scenes and the rangethat cameras capture. It describes how electronic image processinghas been used to render HDR scenes since 1967, and examines thegreat variety of HDR algorithms used today. Showing how spatialprocesses can mimic vision, and render scenes as artists do, thebook also:
* Gives the history of HDR from artists' spatial techniques toscientific image processing
* Measures and describes the limits of HDR scenes, HDR cameraimages, and the range of HDR appearances
* Offers a unique review of the entire family of Retinex imageprocessing algorithms
* Describes the considerable overlap of HDR and Color Constancy:two sides of the same coin
* Explains the advantages of algorithms that replicate humanvision in the processing of HDR scenes
* Provides extensive data to test algorithms and models of visionon an accompanying website
