Rendering High Dynamic Range (HDR) scenes on media with limited dynamic range began in the Renaissance whereby painters, then photographers, learned to use low-range spatial techniques to synthesize appearances, rather than to reproduce accurately the light from scenes. The Art and Science of HDR Imaging presents a unique scientific HDR approach derived from artists’ understanding of painting, emphasizing spatial information in electronic imaging. Human visual appearance and reproduction rendition of the HDR world requires spatial-image processing to overcome the veiling glare limits of optical imaging, in eyes and in cameras. Illustrated in full colour throughout, including examples of fine-art paintings, HDR photography, and multiple exposure scenes; this book uses techniques to study the HDR properties of entire scenes, and measures the range of light of scenes and the range that cameras capture. It describes how electronic image processing has been used to render HDR scenes since 1967, and examines the great variety of HDR algorithms used today. Showing how spatial processes can mimic vision, and render scenes as artists do, the book also: Gives the history of HDR from artists' spatial techniques to scientific image processing Measures and describes the limits of HDR scenes, HDR camera images, and the range of HDR appearances Offers a unique review of the entire family of Retinex image processing algorithms Describes the considerable overlap of HDR and Color Constancy: two sides of the same coin Explains the advantages of algorithms that replicate human vision in the processing of HDR scenes Provides extensive data to test algorithms and models of vision on an accompanying website www.wiley.com/go/mccannhdr

The Art, Science, and Craft of Great Landscape Photography, 2nd Edition teaches photographers how to convert their visual peak experiences—moments of extraordinary natural beauty that evoke a sense of wonder and awe—into stunning images that elicit the same awestruck emotion in their viewers. Author Glenn Randall is an experienced wilderness photographer, and whether you want to venture into the mountains for once-in-a-lifetime shots of raw nature, or simply hone your landscape photography skills from the safety of your back deck, Randall explains the art, science and craft behind creating stunning landscape photographs.

This fully updated edition of the best-selling first edition includes nearly all new imagery throughout the book, as well as a new first chapter, "Photographic Essentials," to help beginners to landscape photography get up to speed quickly. Additionally, this second edition takes into account how Randall's techniques have changed and evolved since the first edition published—from photographic practices to how he uses smart phones and apps as important and powerful tools for landscape photography.

After discussing photographic essentials, Randall focuses on the art of landscape photography. He describes his three-step process for composing a photograph and shows how good composition is an organic process that begins with rules but ultimately transcends them. Randall then explores the science behind successful landscape photographs, which requires understanding key concepts from geography, optics, vision, and psychology. These concepts include:

• How the position of the sun at sunrise and sunset varies throughout the year. This will help you plan when and where to shoot.

• Using optics to predict where rainbows will appear, how polarizers will interact with reflections, and where to find spectacular light.

• How to use topographic maps and computerized mapping tools to help you find promising shooting locations in the wilderness.

• Calculating exposures, achieving correct exposure in high-contrast lighting situations, and the best digital darkroom techniques.

With some practice and by applying the techniques that Randall teaches you, you will soon be ready to master the finer nuances of creating magnificent landscape photographs.

Color is a sensation generated both by the interaction of the visual sensors in the eyes with the natural environment and by the elaboration of visual information by higher brain functions. This book presents the mathematical framework needed to deal with several models of color processing of digital images. The book starts with a short yet exhaustive introduction to the basic phenomenological features of color vision, which are constantly used throughout the book. The discussion of computational issues starts with color constancy, which is dealt with in a rigorous and self-contained mathematical setting. Then, the original Retinex model and its numerous variants are introduced and analyzed with direct discrete equations. The remainder of the book is dedicated to the variational analysis of Retinex-like models, contextualizing their action with respect to contrast enhancement.

Starting from psychophysics, over the last 50 years, most progress in unravelling the mechanisms of color vision has been made through the study of single cell responses, mainly in LGN and striate cortex. A similar development in the study of form perception may seem to be underway, centred on the study of temporal cortex. However, because of the combinatorial characteristics of form perception, we are also observing the opposite tendency: from single-cell activity to population coding, and from static receptive field structures to system dynamics and integration and, ultimately, a synthetic form of psychophysics of color and form perception. From single cells to system integration: it is this development the present Research Topic wishes to highlight and promote. How does this development affect our views on the various attributes of perception? In particular, we are interested in to what extent evolving knowledge in the field of color perception is relevant within a developing integrative framework of form perception. The goal of this Research Topic is to bring together experimental research encompassing both color and form perception. For this volume, we planned a broad scope of topics – on color in complex scenes, color and form, as well as dynamic aspects of form perception. We expect that the Research Topic will be attractive to the community of researchers whose work straddles the boundary between the two visual perception fields, as well as to the wider community interested in integrative/systems neuroscience.
