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.

An illuminated tour of Walter Benjamin's ideas; a graphic translation; an encyclopedia of fragments. Walter Benjamin was a man of letters, an art critic, an essayist, a translator, a philosopher, a collector, and an urban flâneur. In his writings, he ambles, samples, and explores. With Walter Benjamin Reimagined , Frances Cannon offers a visual and literary response to Benjamin's work. With detailed and dreamlike pen-and-ink drawings and hand-lettered text, Cannon gives readers an illuminated tour of Walter Benjamin's thoughts—a graphic translation, an encyclopedia of fragments. Cannon has not created a guide to Benjamin's greatest ideas—this is not an illustrated Walter Benjamin cheat sheet—but rather a beautifully rendered work of graphic literature. Cannon doesn't plod through thickets of minutiae; she strolls—a flâneuse herself—using Benjamin's words and her own drawings to construct a creative topography of Benjamin's writing. Phrases from “Unpacking My Library,” for example, are accompanied by images of flying papers, stray books, stacked books—books “not yet touched by the mild boredom of order”—and a bearded mage. Cannon takes the reader through different periods of Benjamin's writing: “Artifacts of Youth,” nostalgic musings on his childhood; “Fragments of a Critical Eye,” early writings, political observations, and cultural criticism; “Athenaeum of Imagination,” meditations on philosophy and psychology; “A Stroll through the Arcades,” Benjamin's unfinished magnum opus; and “A Collection of Dreams and Stories,” experimental and fantastical writings. With drawings and text, Cannon offers a phantasmagorical tribute to Benjamin's wandering eye.
