How the perception of shadows, studied by vision scientists and visual artists, reveals the inner workings of the visual system. In The Visual World of Shadows, Roberto Casati and Patrick Cavanagh examine how the perception of shadows, as studied by vision scientists and visual artists, reveals the inner workings of the visual system. Shadows are at once a massive problem for vision—which must distinguish them from objects or material features of objects—and a resource, signaling the presence, location, shape, and size of objects. Casati and Cavanagh draw up an inventory of information retrievable from shadows, showing their amazing variety. They present an overview of the visual system, distinguishing between measurement and inference. They discuss the shadow mission, the work done by the visual brain to parse, and perhaps discard, the information from shadows; shadow ownership, the association of a shadow with the object that casts it; shadow labeling, the visual system's ability to tell shadows from nonshadows; and the shadow concept, our knowledge about shadows as a category. Casati and Cavanagh then apply the theoretical apparatus they have developed for shadows to other phenomena: illumination, reflection, and transparency. Finally, they examine the art of the shadow, paying tribute to artists' exploration of shadow, analyzing a series of artworks (reproduced in color) from a rich and fascinating art historical corpus.

Colours are all around us and they affect our daily lives, but what exactly are they and what is their function? A closer look at colours raises many questions: Can colour be measured? How does changing illumination affect the perception of colours? What is colour harmony? Do colours affect our emotions? Colours in the Visual World provides answers to these and other questions. It inspires the reader to discover and creatively use colour by tapping artistic knowledge and recent findings of perceptual science. Colours in the Visual World is a resource of colour facts and phenomena for students of art, design, and architecture, as well as all those interested in the world of colour. The book is based on the author’s over 20 years of experience in teaching, researching and creating with colour. Each chapter includes assignments that serve as a starting point for independent study and experimentation. A glossary helps to clarify colour concepts and terminology.

"Shadows are holes in light. We see them all the time, and sometimes we notice them, but their part in our visual experience of the world is mysterious. In this book, an eminent art historian draws on contemporary cognitive science, eighteenth-century theories of visual perception, and art history to discuss shadows and the visual knowledge they can offer. Michael Baxandall begins by describing the physical constitution and different varieties of shadows. He then sketches the eighteenth-century empirical/nativist debate on the role of shadows in the perception of shape. Next he surveys modern research by cognitive scientists and machine vision workers, explaining how research is divided on the issue of how far and by what means shadows help or hinder perception of shape. Baxandall continues his exploration by recounting a neglected episode of shadow theory, the observations of a group of mid-eighteenth-century French scientists and artists on shadows as related to light and space. Finally he sets these various shadow universes into relation with each other, addressing the special problem of painting shadows, and analyzes Chardin's painting The Young Draughtsman, in which shadow painting is both medium and theme. The book includes an appendix that situates and summarizes the shadow system of Leonardo da Vinci, which has had a strong though partly underground influence on thinking about shadows for five hundred years"--Publisher's description.

In this original, wide-ranging, and endlessly thought-provoking work of popular nonfiction, a leading science writer uncovers the pervasive presence of shadows in our world. For Plato, shadows were the symbol of our limitations. For Galileo, they knocked the Earth from the center of the cosmos. They are a source of fear and a symbol of ignorance, and they loom large in art and design, mythology and folklore, physics and metaphysics, and architecture and urban planning. From shadows puppets and the psychology of shadows to the role of shadows in astronomy and the influence of shadows on the architectural profiles of our cities, Roberto Casati awakens our fascination in this tour-de-force of investigation and imagination.

Important elements of games, movies, and other computer-generated content, shadows are crucial for enhancing realism and providing important visual cues. In recent years, there have been notable improvements in visual quality and speed, making high-quality realistic real-time shadows a reachable goal. Real-Time Shadows is a comprehensive guide to the theory and practice of real-time shadow techniques. It covers a large variety of different effects, including hard, soft, volumetric, and semi-transparent shadows. The book explains the basics as well as many advanced aspects related to the domain of shadow computation. It presents interactive solutions and practical details on shadow computation. The authors compare various algorithms for creating real-time shadows and illustrate how they are used in different situations. They explore the limitations and failure cases, advantages and disadvantages, and suitability of the algorithms in several applications. Source code, videos, tutorials, and more are available on the book’s website www.realtimeshadows.com.

In Measuring Shadows, Raz Chen-Morris demonstrates that a close study of Kepler’s Optics is essential to understanding his astronomical work and his scientific epistemology. He explores Kepler’s radical break from scientific and epistemological traditions and shows how the seventeenth-century astronomer posited new ways to view scientific truth and knowledge. Chen-Morris reveals how Kepler’s ideas about the formation of images on the retina and the geometrics of the camera obscura, as well as his astronomical observations, advanced the argument that physical reality could only be described through artificially produced shadows, reflections, and refractions. Breaking from medieval and Renaissance traditions that insisted upon direct sensory perception, Kepler advocated for instruments as mediators between the eye and physical reality, and for mathematical language to describe motion. It was only through this kind of knowledge, he argued, that observation could produce certainty about the heavens. Not only was this conception of visibility crucial to advancing the early modern understanding of vision and the retina, but it affected how people during that period approached and understood the world around them.
