| diagram of camera obscura: Vermeer's Camera Philip Steadman, 2002 Art historians have long speculated on how Vermeer achieved the uncanny mixture of detached precision, compositional repose, and perspective accuracy that have drawn many to describe his work as photographic. Indeed, many wonder if Vermeer employed a camera obscura, a primitive form of camera, to enhance his realistic effects? In Vermeer's Camera, Philip Steadman traces the development of the camera obscura--first described by Leonaro da Vinci--weighs the arguments that scholars have made for and against Vermeer's use of the camera, and offers a fascinating examination of the paintings themselves and what they alone can tell us of Vermeer's technique. Vermeer left no record of his method and indeed we know almost nothing of the man nor of how he worked. But by a close and illuminating study of the paintings Steadman concludes that Vermeer did use the camera obscura and shows how the inherent defects in this primitive device enabled Vermeer to achieve some remarkable effects--the slight blurring of image, the absence of sharp lines, the peculiar illusion not of closeness but of distance in the domestic scenes. Steadman argues that the use of the camera also explains some previously unexplainable qualities of Vermeer's art, such as the absence of conventional drawing, the pattern of underpainting in areas of pure tone, the pervasive feeling of reticence that suffuses his canvases, and the almost magical sense that Vermeer is painting not objects but light itself. Drawing on a wealth of Vermeer research and displaying an extraordinary sensitivity to the subtleties of the work itself, Philip Steadman offers in Vermeer's Camera a fresh perspective on some of the most enchanting paintings ever created. |

| diagram of camera obscura: Traces of Vermeer Jane Jelley, 2017-07-14 Johannes Vermeer's luminous paintings are loved and admired around the world, yet we do not understand how they were made. We see sunlit spaces; the glimmer of satin, silver, and linen; we see the softness of a hand on a lute string or letter. We recognise the distilled impression of a moment of time; and we feel it to be real. We might hope for some answers from the experts, but they are confounded too. Even with the modern technology available, they do not know why there is no evidence of any preliminary drawing; why there are shifts in focus; and why his pictures are unusually blurred. Some wonder if he might possibly have used a camera obscura to capture what he saw before him. The few traces Vermeer has left behind tell us little: there are no letters or diaries; and no reports of him at work. Jane Jelley has taken a new path in this detective story. A painter herself, she has worked with the materials of his time: the cochineal insect and lapis lazuli; the sheep bones, soot, earth, and rust. She shows us how painters made their pictures layer by layer; she investigates old secrets; and hears travellers' tales. She explores how Vermeer could have used a lens in the creation of his masterpieces. The clues were there all along. After all this time, now we can unlock the studio door, and catch a glimpse of Vermeer inside, painting light. |
| diagram of camera obscura: Pixels & Paintings David G. Stork, 2023-11-14 PIXELS & PAINTINGS “The discussion is firmly grounded in established art historical practices, such as close visual analysis and an understanding of artists’ working methods, and real-world examples demonstrate how computer-assisted techniques can complement traditional approaches.” —Dr. Emilie Gordenker, Director of the Van Gogh Museum The pioneering presentation of computer-based image analysis of fine art, forging a dialog between art scholars and the computer vision community In recent years, sophisticated computer vision, graphics, and artificial intelligence algorithms have proven to be increasingly powerful tools in the study of fine art. These methods—some adapted from forensic digital photography and others developed specifically for art—empower a growing number of computer-savvy art scholars, conservators, and historians to answer longstanding questions as well as provide new approaches to the interpretation of art. Pixels & Paintings provides the first and authoritative overview of the broad range of these methods, which extend from image processing of palette, marks, brush strokes, and shapes up through analysis of objects, poses, style, composition, to the computation of simple interpretations of artworks. This book stresses that computer methods for art analysis must always incorporate the cultural contexts appropriate to the art studies at hand—a blend of humanistic and scientific expertise. Describes powerful computer image analysis methods and their application to problems in the history and interpretation of fine art Discusses some of the art historical lessons and revelations provided by the use of these methods Clarifies the assumptions and applicability of methods and the role of cultural contexts in their use Shows how computation can be used to analyze tens of thousands of artworks to reveal trends and anomalies that could not be found by traditional non-computer methods Pixels & Paintings is essential reading for computer image analysts and graphics specialists, conservators, historians, students, psychologists and the general public interested in the study and appreciation of art. |

| diagram of camera obscura: Techniques of the Observer Jonathan Crary, 1992-02-25 Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of subjective vision were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as realist, were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s. |

| diagram of camera obscura: Turin Shroud: How Leonardo Da Vinci Fooled History Lynn Picknett, Clive Prince, 2012-07-19 In 1988, carbon dating of the world's most famous Christian relic revealed that it was a mediaeval or Renaissance forgery. Yet many questions remained. How could a hoaxer of 500 or more years ago have created an image that appears so astonishingly lifelike when seen in photographic negative? How was such an image formed? And who would have dared fake the Holy Shroud of Jesus? Setting out to answer these questions, Lynn Picknett and Clive Prince discovered that the faker was none other than Leonardo da Vinci, the Renaissance artist, scientist, inventor - and hoaxer - whose innovations are acknowledged to have been centuries ahead of his time. They also reconstructed Leonardo's secret technique - becoming the first ever to recreate the Shroud image. Now revised and updated, sensationally the new 2006 edition of Turin Shroud presents the long-lost hard evidence to link the Shroud of Turin directly with Leonardo da Vinci. Perhaps this is even his 'confession' to having faked Christianity's most sacred relic, which will astonish both believers and sceptics alike, and present a new challenge to historians of both art and photography. |
| diagram of camera obscura: Science in Medieval Islam Howard R. Turner, 2010-07-28 A “well-organized and interesting” overview of science in the Muslim world in the seventh through seventeenth centuries, with over 100 illustrations (The Middle East Journal). During the Golden Age of Islam, in the seventh through seventeenth centuries A. D., Muslim philosophers and poets, artists and scientists, princes and laborers created a unique culture that has influenced societies on every continent. This book offers a fully illustrated, highly accessible introduction to an important aspect of that culture: the scientific achievements of medieval Islam. Howard Turner, who curated the subject for a major traveling exhibition, opens with a historical overview of the spread of Islamic civilization from the Arabian peninsula eastward to India and westward across northern Africa into Spain. He describes how a passion for knowledge led the Muslims during their centuries of empire-building to assimilate and expand the scientific knowledge of older cultures, including those of Greece, India, and China. He explores medieval Islamic accomplishments in cosmology, mathematics, astronomy, astrology, geography, medicine, natural sciences, alchemy, and optics. He also indicates the ways in which Muslim scientific achievement influenced the advance of science in the Western world from the Renaissance to the modern era. This survey of historic Muslim scientific achievements offers students and other readers a window into one of the world’s great cultures, one which is experiencing a remarkable resurgence as a religious, political, and social force in our own time. |
| diagram of camera obscura: Fractal Narrative German A. Duarte, 2014-09-30 Fractals suggest recursivity, infinity and the repetition of a principle of order. They are digital pictures of the universe's continuous movement ignored by mankind during millennia. This book investigates the relationship existing between geometries and technology, and how it guided cognitive processes and thus the organization of narrative spaces. The author proposes a new approach for the study of media remarking that from Bacon's camera obscura to von Neumann's computers both geometries and technology strongly influenced the organization of narrative spaces, which acquired a fractal character. |

| diagram of camera obscura: An Eye for Art National Gallery of Art, 2013-09-01 Lavishly illustrated with 230 full color images, this family-oriented art resource introduces children ages 7 to 12, as well as their parents and educators, to more than 50 great artists and their work, with corresponding activities and explorations that inspire artistic development, focused looking, and even creative writing. Thematic chapters range from examining portraiture and landscape to playing with space and storytelling. Within each chapter a diverse range of American and European artists, art mediums, and time periods is represented. This treasure trove of artwork from the National Gallery of Art includes, among others, works by Raphael, Rembrandt, Georgia O’Keeffe, Henri Matisse, Chuck Close, Jacob Lawrence, Pablo Picasso, and Alexander Calder, representing a wide range of artistic styles and techniques. Written by museum educators with decades of hands-on experience in both art-making activities and making art relatable to children, the activities include sculpting a clay figure inspired by Edgar Degas; drawing an object from touch alone, inspired by Joan Miro’s experience as an art student; painting a double-sided portrait with one side reflecting physical traits and the other side personality traits, inspired by Leonardo da Vinci’s Ginevra de' Benci; and creating a story based on a Mary Cassatt painting. Educators, homeschoolers, and families alike will find their creativity sparked by this art extravaganza. The National Gallery of Art in Washington, DC, maintains one of the world's most renowned collections of American and European masterpieces from the thirteenth century to the present. An important component of the National Gallery of Art is its educational mission. This book was written and compiled by the museum's educators and is a collective effort of the Education Division at the National Gallery of Art. |

| diagram of camera obscura: Leonardo Da Vinci's Elements of the Science of Man Kenneth D. Keele, 2014-05-10 Leonardo Da Vinci's Elements of the Science of Man describes how Da Vinci integrates his mechanical observations and experiments in mechanics into underlying principles. This book is composed of 17 chapters that highlight the principles underlying Da Vinci's research in anatomical studies. Considerable chapters deal with Leonardo's scientific methods and the mathematics of his pyramidal law, as well as his observations on the human and animal movements. Other chapters describe the artist's anatomical approach to the mechanism of the human body, specifically the physiology of vision, voice, music, senses, soul, and the nervous system. The remaining chapters examine the mechanism of the bones, joints, respiration, heart, digestion, and urinary and reproductive systems. |
| diagram of camera obscura: The Psychology of Perspective and Renaissance Art Michael Kubovy, 1986 Michael Kubovy, an experimental psychologist, recounts the lively history of the invention of perspective in the fifteenth century, and shows how, as soon as the invention spread, it was used to achieve subtle and fascinating aesthetic effects. A clear presentation of the fundamental concepts of perspective and the reasons for its effectiveness, drawing on the latest laboratory research on how people perceive, leads into the development of a new theory to explain why Renaissance artists such as Leonardo and Mantegna used perspective in unorthodox ways which have puzzled art scholars. This theory illuminates the author's broader consideration of the evolution of art: the book proposes a resolution of the debate between those who believe that the invention/discovery of perspective is a stage in the steady progress of art and those who believe that perspective is merely a conventional and arbitrary system for the representation of space. |

| diagram of camera obscura: Perceiving in Depth, Volume 1: Basic Mechanisms Ian P. Howard, 2012-01-27 The three-volume work Perceiving in Depth is a sequel to Binocular Vision and Stereopsis and to Seeing in Depth, both by Ian P. Howard and Brian J. Rogers. This work is much broader in scope than the previous books and includes mechanisms of depth perception by all senses, including aural, electrosensory organs, and the somatosensory system. Volume 1 reviews sensory coding, psychophysical and analytic procedures, and basic visual mechanisms. Volume 2 reviews stereoscopic vision. Volume 3 reviews all mechanisms of depth perception other than stereoscopic vision. The three volumes are extensively illustrated and referenced and provide the most detailed review of all aspects of perceiving the three-dimensional world. Volume 1 starts with a review of the history of visual science from the ancient Greeks to the early 20th century with special attention devoted to the discovery of the principles of perspective and stereoscopic vision. The first chapter also contains an account of early visual display systems, such as panoramas and peepshows, and the development of stereoscopes and stereophotography. A chapter on the psychophysical and analytic procedures used in investigations of depth perception is followed by a chapter on sensory coding and the geometry of visual space. An account of the structure and physiology of the primate visual system proceeds from the eye through the LGN to the visual cortex and higher visual centers. This is followed by a review of the evolution of visual systems and of the development of the mammalian visual system in the embryonic and post-natal periods, with an emphasis on experience-dependent neural plasticity. An account of the development of perceptual functions, especially depth perception, is followed by a review of the effects of early visual deprivation during the critical period of neural plasticity on amblyopia and other defects in depth perception. Volume 1 ends with accounts of the accommodation mechanism of the human eye and vergence eye movements. |

| diagram of camera obscura: The Reciprocity of Perceiver and Environment Thomas J. Lombardo, 2017-03-27 Originally published in 1987, this title intended to historically reveal, through tracing Gibson’s development, the substance of his views and how they bore upon general philosophical issues in theories of knowledge, and to investigate in detail the historical context of Gibson’s theoretical position within psychology. Though the author has included a history of Gibson’s perceptual research and experimentation, the focus is to explicate the ‘dynamic abstract form’ of Gibson’s ecological approach. His emphasis is philosophical and theoretical, attempting to bring out the direction Gibson was moving in and how such changes could restructure the theoretical fabric of psychology. He devotes considerable attention to the Greeks, Medievalists, and the founders of the Scientific Revolution. This is because Gibson’s theoretical challenge runs deep into the structure of western thought. The authors’ central goal was to set Gibson’s ecological theory within the historical context of fundamental philosophical-scientific issues. |

| diagram of camera obscura: Symmetry As A Developmental Principle In Nature And Art Werner Hahn, 1998-10-16 Looking beyond the boundaries of various disciplines, the author demonstrates that symmetry is a fascinating phenomenon which provides endless stimulation and challenges. He explains that it is possible to readapt art to the sciences, and vice versa, by means of an evolutionary concept of symmetry. Many pictorial examples are included to enable the reader to fully understand the issues discussed. Based on the artistic evidence that the author has collected, he proposes that the new ars evolutoria can function as an example for the sciences.The book is divided into three distinct parts, each one focusing on a special issue. In Part I, the phenomenon of symmetry, including its discovery and meaning is reviewed. The author looks closely at how Vitruvius, Polyclitus, Democritus, Plato, Aristotle, Plotinus, Augustine, Alberti, Leonardo da Vinci and Durer viewed symmetry. This is followed by an explanation on how the concept of symmetry developed. The author further discusses symmetry as it appears in art and science, as well as in the modern age. Later, he expounds the view of symmetry as an evolutionary concept which can lead to a new unity of science. In Part II, he covers the points of contact between the form-developing process in nature and art. He deals with biological questions, in particular evolution.The collection of new and precise data on perception and knowledge with regard to the postulated reality of symmetry leads to further development of the evolutionary theory of symmetry in Part III. The author traces the enormous treasure of observations made in nature and culture back to a few underlying structural principles. He demonstrates symmetry as a far-reaching, leading, structuring, causal element of evolution, as the idea lying behind nature and culture. Numerous controllable reproducible double-mirror experiments on a new stereoscopic vision verify a symmetrization theory of perception. |
| diagram of camera obscura: 4D Electron Microscopy Ahmed H. Zewail, John Meurig Thomas, 2010 Structural phase transitions, mechanical deformations, and the embryonic stages of melting and crystallization are examples of phenomena that can now be imaged in unprecedented structural detail with high spatial resolution, and ten orders of magnitude as fast as hitherto. No monograph in existence attempts to cover the revolutionary dimensions that EM in its various modes of operation nowadays makes possible. The authors of this book chart these developments, and also compare the merits of coherent electron waves with those of synchrotron radiation. They judge it prudent to recall some important basic procedural and theoretical aspects of imaging and diffraction so that the reader may better comprehend the significance of the new vistas and applications now afoot. This book is not a vade mecum - numerous other texts are available for the practitioner for that purpose. |

| diagram of camera obscura: Science in Culture Stephen R. Graubard, 2018-04-27 Twenty-five years ago, Gerald Holton's Thematic Origins of Scientific Thought introduced a wide audience to his ideas. Holton argued that from ancient times to the modern period, an astonishing feature of innovative scientific work was its ability to hold, simultaneously, deep and opposite commitments of the most fundamental sort. Over the course of Holton's career, he embraced both the humanities and the sciences. Given this background, it is fitting that the explorations assembled in this volume reflect both individually and collectively Holton's dual roots. In the opening essay, Holton sums up his long engagement with Einstein and his thematic commitment to unity. The next two essays address this concern. In historicized form, Lorraine Daston returns the question of the scientific imagination to the Enlightenment period when both sciences and art feared imagination. Daston argues that the split whereby imagination was valued in the arts and loathed in the sciences is a nineteenth-century divide. James Ackerman on Leonardo da Vinci meshes perfectly with Daston's account, showing a form of imaginative intervention where it is irrelevant to draw analogies between art and science. Historians of religion Wendy Doniger and Gregory Spinner pursue the imagination into the bedroom with literary-theological representations. Science, culture, and the imagination also intersect with biologist Edward Wilson and physicist Steven Weinberg. Both tackle the big question of the unity of knowledge and worldviews from a scientific perspective while art historian Ernst Gombrich does the same from the perspective of art history. To emphasize the nitty-gritty of scientific practice, chemists Bretislav Fredrich and Dudley Herschback provide a remarkable historical tour at the boundary of chemistry and physics. In the concluding essay, historian of education Patricia Albjerg Graham addresses pedagogy head-on. In these various reflections on science, art, literature, philosophy, and education, this volume gives us a view in common: a deep and abiding respect for Gerald Holton's contribution to our understanding of science in culture.

| diagram of camera obscura: The Vital Landscape William M. Taylor, 2017-11-22 The Vital Landscape explores the arrival of the biological sciences - most notably the sciences oflife entailed in studies of botany and zoology, ecology and evolutionary science, physiology and psychology - in the nineteenth century and their impact on architecture and landscape architecture in Great Britain. Specifically, the book explores the idea of the contrived or artificial environment as an object of both scientific speculation and aesthetic reflection. Unlike specialist histories of biological science or environmental thought, this book is unique in locating one source for present-day concerns for the environment and human well-being in debates over proper housing and the growing popularity of domestic and public gardens in the nineteenth century. The book skilfully interweaves architecture and garden history, the history and philosophy of science, plant and animal physiology and human psychology, works of literature, popular science and domestic economy in a story that opens new opportunities for the study of architecture and gardens. |

| diagram of camera obscura: Pure Intelligence Melvyn C. Usselman, 2015-05-21 William Hyde Wollaston was born into a large, religious, and scientifically informed family in 1766 and died sixty-two years later as one of the Western world s most highly regarded scientists. With encouragement from his well-connected father, he studied medicine at Cambridge, and began practicing as a physician in the provinces before moving his practice to London in 1797, arriving in the capital about the same time as his illustrious colleagues Humphry Davy and Thomas Young. After a few years in London, Wollaston abandoned the vocation he had come to dislike and bravely set out to make his living as a chemical entrepreneur, while pursuing his intellectual interests in a wide range of contemporary scientific subjects. He, Davy, and Young were to become Britain s leading scientific practitioners in the first third of the nineteenth century, and their deaths within a six month time span were seen by many as the end of a glorious period of British supremacy in science. In contrast to his two more famous colleagues, Wollaston s life was not recorded for posterity in a contemporary biography, and his many remarkable scientific, commercial, instrumental, and institutional achievements have fallen into obscurity as a result. This biography is the first book-length study of Wollaston, his science, and the environment in which he thrived. |
