At the Edges of Vision


Book Description

In At the Edges of Vision, Ren?van de Vall re-examines the aesthetics of spectatorship in terms of new-media art and visual culture. The aesthetic experience of visual art has traditionally been described in terms of the distanced contemplation and critical interpretation of the work's form and representational content. Recent developments in installation, video and computer art have foregrounded the bodily and affective engagement of the spectator and, in retrospect, throw into question the model of spectatorial distance for more traditional art forms as well. But what does this development entail for art's potential for reflective, imaginative and experiential depth? Is art still capable of providing a critical counterpoint to the ubiquitous presence of sensational, yet short-lived media imagery when it speaks to the senses rather than to the mind? In a thorough examination of examples from painting, film, installation art and interactive video, and computer art, Van de Vall argues for a tactile and affective conception of reflection, linking philosophy and art. Looking at a Rembrandt self-portrait and navigating through an internet art work have in common that both types of work rely on a playful, rhythmically structured, sensuous and embodied reflexivity for the articulation of meaning. This sensuous dimension of playful reflexivity is just as important in philosophical thought, however, as the transcendental condition for genuine, open-ended reflection. Drawing on the philosophy of Merleau-Ponty, Levinas, Lyotard and Deleuze on the one hand and on new-media theory on the other, Van de Vall develops a performative phenomenology of aesthetic reflection, visuality and visual art, in order to rethink art's ethical and political relevance in present-day digital-media culture.




The Edge of Vision


Book Description

From the beginning, abstraction has been intrinsic to photography, and its persistent popularity reveals much about the medium. Now available in an affordable paperback edition, The Edge of Vision: The Rise of Abstraction in Photography is the first book in English to document this phenomenon and to put it into historical context, while also examining the diverse approaches thriving within contemporary photography. Author Lyle Rexer examines abstraction at pivotal moments, starting with the inception of photography, when many of the pioneers believed the camera might reveal other aspects of reality. The Edge of Vision traces subsequent explorations--from the Photo-Secessionists, who emphasized process and emotional expression over observed reality, to Modernist and Surrealist experiments. In the decades to follow, in particular from the 1950s through the 1980s, a multitude of photographers--Edward Weston, Aaron Siskind, Barbara Kasten, Ellen Carey and James Welling among them--took up abstraction from a variety of positions. Finally, Rexer explores the influence the history of abstraction exerts on contemporary thinking about the medium. Many contemporary artists--most prominently Penelope Umbrico, Michael Flomen, and Adam Broomberg and Oliver Chanarin--reject classic definitions of photography's documentary dimension in favor of other conceptually inflected possibilities, somewhere between painting and sculpture, that include the manipulation of process and printing. In addition to Rexer's engagingly written and richly illustrated history, this volume includes a selection of primary texts from and interviews with key practitioners and critics, such as Alvin Langdon Coburn, László Moholy-Nagy, Gottfried Jägger, Silvio Wolf and Walead Beshty.




Making Eye Health a Population Health Imperative


Book Description

The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

At the Edge of Sight


Book Description

The advent of photography revolutionized perception, making visible what was once impossible to see with the human eye. In At the Edge of Sight, Shawn Michelle Smith engages these dynamics of seeing and not seeing, focusing attention as much on absence as presence, on the invisible as the visible. Exploring the limits of photography and vision, she asks: What fails to register photographically, and what remains beyond the frame? What is hidden by design, and what is obscured by cultural blindness? Smith studies manifestations of photography's brush with the unseen in her own photographic work and across the wide-ranging images of early American photographers, including F. Holland Day, Eadweard Muybridge, Andrew J. Russell, Chansonetta Stanley Emmons, and Augustus Washington. She concludes by showing how concerns raised in the nineteenth century remain pertinent today in the photographs of Abu Ghraib. Ultimately, Smith explores the capacity of photography to reveal what remains beyond the edge of sight.

Visual Impairments


Book Description

When children and adults apply for disability benefits and claim that a visual impairment has limited their ability to function, the U.S. Social Security Administration (SSA) is required to determine their eligibility. To ensure that these determinations are made fairly and consistently, SSA has developed criteria for eligibility and a process for assessing each claimant against the criteria. Visual Impairments: Determining Eligibility for Social Security Benefits examines SSA's methods of determining disability for people with visual impairments, recommends changes that could be made now to improve the process and the outcomes, and identifies research needed to develop improved methods for the future. The report assesses tests of visual function, including visual acuity and visual fields whether visual impairments could be measured directly through visual task performance or other means of assessing disability. These other means include job analysis databases, which include information on the importance of vision to job tasks or skills, and measures of health-related quality of life, which take a person-centered approach to assessing visual function testing of infants and children, which differs in important ways from standard adult tests.
