Light and Photomedia: A New History and Future of the Photographic Image (International Library Of Visual Culture Ser.)
by Jai McKenzieLight and Photomedia proposes that, regardless of technological change, the history and future of photomedia is essentially connected to light. It is a fundamental property of photomedia, binding with space and time to form and inform new, explicitly light-based structures and experiences. Jai McKenzie identifies light-space-time structures throughout the history of photomedia, from the early image machines through analogue and digital image machines to the present day. She proposes that they will continue to develop in the future and takes us to future image machines of the year 2039. With the use of the theories of Paul Virilio, Jean Baudrillard and Vilem Flusser, featuring artists including Henri Cartier-Bresson, Nam June Paik, Yves Klein, Eadweard Muybridge, Martha Rosler, Cindy Sherman and Michael Snow, as well as their photographic images, Light and Photomedia places the reader in a new history and future which, although mostly overlooked by the canon of photomedia theory, is an essential line of enquiry for contemporary thinking and dialogue in photography.

Lighter than Air Robots: Guidance and Control of Autonomous Airships
by Yasmina Bestaoui SebbaneAn aerial robot is a system capable of sustained flight with no direct human control and able to perform a specific task. A lighter than air robot is an aerial robot that relies on the static lift to balance its own weight. It can also be defined as a lighter than air unmanned aerial vehicle or an unmanned airship with sufficient autonomy. Lighter than air systems are particularly appealing since the energy to keep them airborne is small. They are increasingly considered for various tasks such as monitoring, surveillance, advertising, freight carrier, transportation. This book familiarizes readers with a hierarchical decoupled planning and control strategy that has been proven efficient through research. It is made up of a hierarchy of modules with well defined functions operating at a variety of rates, linked together from top to bottom. The outer loop, closed periodically, consists of a discrete search that produces a set of waypoints leading to the goal while avoiding obstacles and weighed regions. The second level smoothes this set so that the generated paths are feasible given the vehicle's velocity and accelerations limits. The third level generates flyable, timed trajectories and the last one is the tracking controller that attempts to minimize the error between the robot measured trajectory and the reference trajectory. This hierarchy is reflected in the structure and content of the book. Topics treated are: Modelling, Flight Planning, Trajectory Design and Control. Finally, some actual projects are described in the appendix. This volume will prove useful for researchers and practitioners working in Robotics and Automation, Aerospace Technology, Control and Artificial Intelligence.
Lighting & Design for Portrait Photography
by Neil Van NiekerkSome photographers make portraits that we can’t take our eyes off of. These images create mood, evoke emotion, and pique our curiosity. They have that certain something that other portraits seem to lack. These rare images are memorable-the kind of shots that clients want and photographers strive to emulate. These portraits are technically precise and have style. Neil van Niekerk is a big name in the portrait and wedding photography industry. His masterful photographs get a reaction, and he’s devoted to helping others create compelling portraits for their clients. In this book, van Niekerk shows readers strategies for creating a wide range of portrait looks (romantic, fun, sweet, dramatic, glamorous, or moody) in lackluster, middle-of-nowhere locales, small home studios, big expanses, and even on rooftops. Starting with traditional lighting and posing strategies and moving through "spicier” varieties, he shows readers how integrating specialized lighting (rim lighting, backlighting, flare, and low-key lighting-using natural light and artificial sources) and compositional approaches (shallow depth of field, lens compression, and unorthodox perspectives) into their creative approach can allow them to take full creative control over their portrait-taking process so that they’re able to deliver incredible shots of their clients in any photographic conditions.

Lightroom 3
by Nat Coalson"I've worked my entire adult life in digital imaging, from managing high-volume production departments to running my own photography and printing businesses. And for many years, I've been teaching photographers how to be self-sufficient when it comes to working with their digital images.Having used all major image editing software released over the past twenty years, I now choose to use Lightroom because it allows me to work quickly, helps me deal with large numbers of images and lets me get back to enjoying the creative aspects of photography.From my experience, I know how hard it can be to learn new ways of doing things-especially computer stuff. Unfortunately for a lot of photographers, struggling with digital processing can take the fun out of photography. Trying to figure out the intricacies of file formats, resolution, color management, etc., and even simply where to put all the files can be daunting tasks. Worse yet, sometimes it's hard just to know the right steps to get the best quality from a single photo!It's my mission to ease your pain; to show you that you really can be in control of your entire imaging process, and help you develop a personalized workflow that fits your style and needs. My students frequently tell me how liberating this is: to comfortably handle all the files coming off the camera and residing on hard disks, to work methodically through a known sequence of steps and to produce finished pictures that you're proud to show other people. This is at the heart of the photographer's experience, and I want you to know this sense of confidence and capability.I've taught large groups and individual photographers alike. Over the years I've learned where people get stuck. I understand the pitfalls new users face when first starting to use Lightroom as well as the concerns of more experienced users looking for ways to tweak their workflow for better performance. I want to help you overcome these challenges.My goal for this book is to teach you to effectively use Lightroom 3 as quickly and easily as possible. My writing has been heavily influenced by my experiences working with clients and students, and I've approached the content of this book as I would tutor someone in a one-on-one training session. The order in which concepts are presented and the emphasis I give to certain aspects of the workflow are unique among books of its kind.We'll start by reviewing some important, basic principles, such as working with Lightroom catalogs, the Lightroom workflow, color management, and an introduction to Lightroom 3's updated tools and screen interface. From there, we jump right in to importing images into Lightroom. This is followed by a step-by-step editing tutorial that will make your work much easier. Then we move on to in-depth explanations of how to perfect each photo for tone, color, contrast, sharpness and much more. After a detailed look at exporting images out of Lightroom, the next three chapters deal with presenting your work to others with prints, Web sites and slideshows. Finally, we'll wrap up with an in-depth look at advanced techniques for integrating Lightroom with other software.The material presented in this book is appropriate for digital photographers working in all disciplines, at all skill levels. The information and tutorials are applicable to every kind of photography: from weddings and portraits to fine art landscape work, everyone can learn to streamline their digital photography process using Lightroom 3."Nat CoalsonConifer, CO2010
