Visual Worlds

As many observers have noted, the world is becoming increasingly visually mediated, with the rise of computers and the internet being central factors in the emergence of new tools and conventions. Exploring the social structure of visuality, this volume contains a collection of essays by internationally renowned artists and scholars from a variety of fields (including art history, literary theory and criticism, cultural studies, film and television studies, intellectual history and sociology). It was conceived to address a bold query: how is our experience and understanding of vision and visual form changing under pressure from the various social, economic and cultural factors that are linked under the term 'globalization'. The essays overlap in their considerations of the tensions between cultures and worlds, political life, everyday social experience, and war. The resulting conversation that develops between the chapters touches on points from many visual worlds, and provides a unique opportunity for considering the changing character of visual experience today. This book will attract readers from a wide range of academic disciplines and will especially be valuable as a textbook for graduate and undergraduate courses in visual culture and cultural studies.

"A next-generation college textbook that introduces Visual Culture in the arts and sciences"--

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.

The critical role of visual literacies in the 21st century realm is widely acknowledged and the construction of the profile of the visual literate person as a responsible participant in the face of global challenged is a top listed goal in nowadays agenda.

Privileging the visual as the main method of communication and meaning-making, this book responds critically to the worldwide discussion about the Arctic and the North, addressing the interrelated issues of climate change, ethics and geopolitics. A multi-disciplinary, multi-modal exploration of the Arctic, it supplies an original conceptualization of the Arctic as a visual world encompassing an array of representations, imaginings, and constructions. By examining a broad range of visual forms, media and forms such as art, film, graphic novels, maps, media, and photography, the book advances current debates about visual culture. The book enriches contemporary theories of the visual taking the Arctic as a spatial entity and also as a mode of exploring contemporary and historical visual practices, including imaginary constructions of the North. Original contributions include case studies from all the countries along the Arctic shore, with Russian material occupying a large section due to the country’s impact on the region

Publisher Description

The central form of communication on social network sites (sns) is the communication with and through images. Accordingly, the present volume highlights images and image-based communication on sns, such as Facebook, and on nightlife platforms, such as Tilllate. First, the authors analyze the two central image categories in depth - profile images and photo albums. What follows is the portrayal of dramaturgical and staging strategies of the (semi) professional photography on the nightlife platforms, which leads to an evaluation of the importance of the international glamour photography as a parameter of private photographic self-expression. Other questions that the authors ponder in the volume are: Which functions and meanings do images have for the communications between users on social network sites? To what extent could certain design characteristics in the image-based communication on sns establish themselves as prototypical staging patterns? Which staging traditions are followed thereby? Which staging strategies are followed on different online platforms by the users' (self) visualizations?

This comprehensively updated and expanded revision of the successful second edition continues to provide detailed coverage of the ever-growing range of research topics in vision. In Part I, the treatment of visual physiology has been extensively revised with an updated account of retinal processing, a new section explaining the principles of spatial and temporal filtering which underlie discussions in later chapters, and an up-to-date account of the primate visual pathway. Part II contains four largely new chapters which cover recent psychophysical evidence and computational model of early vision: edge detection, perceptual grouping, depth perception, and motion perception. The models discussed are extensively integrated with physiological evidence. All other chapters in Parts II, III, and IV have also been thoroughly updated.
