An account of Western visual technologies since the Renaissance traces a history of the increasing control of light's intrinsic excess. Light is the condition of all vision, and the visual media are our most important explorations of this condition. The history of visual technologies reveals a centuries-long project aimed at controlling light. In this book, Sean Cubitt traces a genealogy of the dominant visual media of the twenty-first century—digital video, film, and photography—through a history of materials and practices that begins with the inventions of intaglio printing and oil painting. Attending to the specificities of inks and pigments, cathode ray tubes, color film, lenses, screens, and chips, Cubitt argues that we have moved from a hierarchical visual culture focused on semantic values to a more democratic but value-free numerical commodity. Cubitt begins with the invisibility of black, then builds from line to surface to volume and space. He describes Rembrandt's attempts to achieve pure black by tricking the viewer and the rise of geometry as a governing principle in visual technology, seen in Dürer, Hogarth, and Disney, among others. He finds the origins of central features of digital imaging in nineteenth-century printmaking; examines the clash between the physics and psychology of color; explores the representation of space in shadows, layers, and projection; discusses modes of temporal order in still photography, cinema, television, and digital video; and considers the implications of a political aesthetics of visual technology.

In Jamaican dancehalls competition for the video camera's light is stiff, so much so that dancers sometimes bleach their skin to enhance their visibility. In the Bahamas, tuxedoed students roll into prom in tricked-out sedans, staging grand red-carpet entrances that are designed to ensure they are seen being photographed. Throughout the United States and Jamaica friends pose in front of hand-painted backgrounds of Tupac, flashy cars, or brand-name products popularized in hip-hop culture in countless makeshift roadside photography studios. And visual artists such as Kehinde Wiley remix the aesthetic of Western artists with hip-hop culture in their portraiture. In Shine, Krista Thompson examines these and other photographic practices in the Caribbean and United States, arguing that performing for the camera is more important than the final image itself. For the members of these African diasporic communities, seeking out the camera's light—whether from a cell phone, Polaroid, or video camera—provides a means with which to represent themselves in the public sphere. The resulting images, Thompson argues, become their own forms of memory, modernity, value, and social status that allow for cultural formation within and between African diasporic communities.

"When I begin to write, I open myself and wait. And when I turn toward an inner spiritual awareness, I open myself and wait." With that insight, Pat Schneider invites readers to contemplate their lives and deepest questions through writing. In seventeen concise thematic chapters that include meditations on topics such as fear, freedom, tradition in writing and in religions, forgiveness, joy, social justice, and death, How the Light Gets In gracefully guides readers through the artistic and spiritual questions that life offers to everyone. Praised as a "fuse lighter" by author Julia Cameron and "the wisest teacher of writing I know" by the celebrated writing guru Peter Elbow, Pat Schneider has lived a life of writing and teaching, passion and compassion. With How the Light Gets In, she delves beyond the typical "how-to's" of writing to offer an extended rumination on two inner paths, and how they can run as one. Schneider's book is distinct from the many others in the popular spirituality and creative writing genre by virtue of its approach, using one's lived experience--including the experience of writing--as a springboard for expressing the often ineffable events that define everyday life. Her belief that writing about one's own life leads to greater consciousness, satisfaction, and wisdom energizes the book and carries the reader elegantly through difficult topics. As Schneider writes, "All of us live in relation to mystery, and becoming conscious of that relationship can be a beginning point for a spiritual practice--whether we experience mystery in nature, in ecstatic love, in the eyes of our children, our friends, the animals we love, or in more strange experiences of intuition, synchronicity, or prescience."

This is the first book to introduce the fourteen joyful and highly symbolic events that make up the Via Lucis, the Christian Way of Light, an ancient spiritual tradition celebrating the post-Resurrection life of Christ on Earth. The Stations of the Light, with its “good news” of healing and salvation, is becoming an increasingly popular devotion throughout the United States and the world, and was recognized by the Vatican in its Jubilee 2000 campaign. While Christians of all denominations are familiar with the Stations of the Cross, few know how to celebrate the Stations of the Light, a practice that came into being through inspiration from ancient Roman sources. Stations of the Light is a clear and inspiring guide to making this ancient ritual part of contemporary Christian life. The stations mark the fourteen sacred events in the post-Easter story, from “Jesus Rises from the Dead” to “Pentecost: The Risen Lord Sends the Holy Spirit.” For each one, Mary Ford-Grabowsky presents a variety of spiritual practices that invite readers to form their own realistic and sacred image of the event. Beginning with relaxation and releasing the imagination, these exercises are designed to help convey the story and foster inspiration, and include ancient and contemporary meditations, reflections, and prayers; as well as journal writing, artwork, music, and mantras.

Light symbolises the highest good, it enables all visual art, and today it lies at the heart of billion-dollar industries. The control of light forms the foundation of contemporary vision. Digital Light brings together artists, curators, technologists and media archaeologists to study the historical evolution of digital light-based technologies. Digital Light provides a critical account of the capacities and limitations of contemporary digital light-based technologies and techniques by tracing their genealogies and comparing them with their predecessor media. As digital light remediates multiple historical forms (photography, print, film, video, projection, paint), the collection draws from all of these histories, connecting them to the digital present and placing them in dialogue with one another. Light is at once universal and deeply historical. The invention of mechanical media (including photography and cinematography) allied with changing print technologies (half-tone, lithography) helped structure the emerging electronic media of television and video, which in turn shaped the bitmap processing and raster display of digital visual media. Digital light is, as Stephen Jones points out in his contribution, an oxymoron: light is photons, particulate and discrete, and therefore always digital. But photons are also waveforms, subject to manipulation in myriad ways. From Fourier transforms to chip design, colour management to the translation of vector graphics into arithmetic displays, light is constantly disciplined to human purposes. In the form of fibre optics, light is now the infrastructure of all our media; in urban plazas and handheld devices, screens have become ubiquitous, and also standardised. This collection addresses how this occurred, what it means, and how artists, curators and engineers confront and challenge the constraints of increasingly normalised digital visual media. While various art pieces and other content are considered throughout the collection, the focus is specifically on what such pieces suggest about the intersection of technique and technology. Including accounts by prominent artists and professionals, the collection emphasises the centrality of use and experimentation in the shaping of technological platforms. Indeed, a recurring theme is how techniques of previous media become technologies, inscribed in both digital software and hardware. Contributions include considerations of image-oriented software and file formats; screen technologies; projection and urban screen surfaces; histories of computer graphics, 2D and 3D image editing software, photography and cinematic art; and transformations of light-based art resulting from the distributed architectures of the internet and the logic of the database. Digital Light brings together high profile figures in diverse but increasingly convergent fields, from academy award-winner and co-founder of Pixar, Alvy Ray Smith to feminist philosopher Cathryn Vasseleu.

A world-renowned expert in lucid dreaming and Tibetan dream yoga guides us into the tradition’s daytime practices, a complement to the nighttime practices taught in his previous book Dream Yoga. Most of us are absolutely certain that we’re awake here and now—it’s a given, right? Yet, according to Tibet’s dream yoga tradition, ordinary waking life is no more real than the illusions of our nightly dreams. In his previous book Dream Yoga, Andrew Holecek guided us into Tibetan Buddhism’s nocturnal path of lucid dreaming and other dimensions of sleeping consciousness. Now, with Dreams of Light, he offers us an in-depth, step-by-step guide to its daytime practices. Known as the “illusory form” practices, these teachings include insights, meditations, and actions to help us realize the dreamlike nature of our lives. Through an immersive exploration of the tradition, beginners and seasoned practitioners alike will learn everything they need to deeply transform both their sleeping and waking hours. “If you’ve struggled to awaken in your dreams,” teaches Holecek, “these techniques will often spark spontaneous lucidity during sleep. And if you’re already a successful lucid dreamer, they will open you to new depths of experience throughout your day.” For those wishing to explore Tibetan Buddhism’s profound path for awakening to the true nature of reality—day or night—Dreams of Light shows us the way.

Laser Light Scattering: Basic Principles and Practice, Second Edition deals with the technical aspects of laser light scattering, including the basic principles and practice. Topics covered include light scattering theory, optical mixing spectrometry, photon correlation spectroscopy, and interferometry. Experimental methods and methods of data analysis are also described. This book is comprised of eight chapters and begins with a discussion on the interrelationship between laser light scattering and other types of scattering techniques that use X-rays and neutrons, with particular reference to momentum and energy transfers as well as time-averaged and time-dependent scattered intensity. The spectrum of scattered light and a single-particle approach to time-averaged scattered intensity are considered. The following chapters focus on photoelectric detection of the scattered electric field; optical mixing spectrometers; basic equations for photon correlation spectroscopy; and the principles of Fabry-Perot interferometry. The pertinent features of the experimental aspects of laser light scattering are also outlined, together with the Laplace inversion problem. The final chapter examines polymer molecular-weight distributions in relation to particle sizing. This monograph will be of interest to physicists.

An examination of telepresence technologies through the lens of contemporary artistic experiments, from early video art through current “drone vision” works. "Telepresence” allows us to feel present—through vision, hearing, and even touch—at a remote location by means of real-time communication technology. Networked devices such as video cameras and telerobots extend our corporeal agency into distant spaces. In Here/There, Kris Paulsen examines telepresence technologies through the lens of contemporary artistic experiments, from early video art through current “drone vision” works. Paulsen traces an arc of increasing interactivity, as video screens became spaces for communication and physical, tactile intervention. She explores the work of artists who took up these technological tools and questioned the aesthetic, social, and ethical stakes of media that allow us to manipulate and affect far-off environments and other people—to touch, metaphorically and literally, those who cannot touch us back. Paulsen examines 1970s video artworks by Vito Acconci and Joan Jonas, live satellite performance projects by Kit Galloway and Sherrie Rabinowitz, and CCTV installations by Chris Burden. These early works, she argues, can help us make sense of the expansion of our senses by technologies that privilege real time over real space and model strategies for engagement and interaction with mediated others. They establish a political, aesthetic, and technological history for later works using cable TV infrastructures and the World Wide Web, including telerobotic works by Ken Goldberg and Wafaa Bilal and artworks about military drones by Trevor Paglen, Omar Fast, Hito Steyerl, and others. These works become a meeting place for here and there.
