Mimicking nature - from science fiction to engineering realityHumans have always looked to nature's inventions as a source of inspiration. The observation of flying birds and insects leads to innovations in aeronautics. Collision avoidance sensors mimic the whiskers of rodents. Optimization algorithms are based on survival of the fittest, the seed-
25 years of nature photography instruction in one gorgeous, full-color, hands-on course Anyone can photograph nature—just step outside and you’re on location. But becoming a good nature photographer takes expert training. In Photographing Nature, Ralph Clevenger, whose images have appeared in such publications as Nature’s Best and National Geographic, shares the techniques he’s been personally using and teaching to aspiring photographers for the last 25 years in his popular nature photography course at the elite Brooks Institute. In this stunning, four-color course-in-a-book, each chapter opens with a spectacular photo spread from the natural world that Clevenger uses to illustrate themes and techniques essential to mastering nature photography. Just as he does in his classroom at Brooks, Clevenger explains how each photo was captured, the tools and techniques used, and typical problems related to capturing such a photo, along with solutions. Chapters also include sample Q&A sessions as well as assignments you can try yourself. By the time you’ve worked through all of the techniques in this beautiful, yet informative book, you’ll not only photograph the world differently, you’ll see it differently as well. With a foreword by George Lepp, one of North America’s best-known contemporary outdoor and nature photographers.
Models need to get hired, designers need to sell their clothing, magazine editors need to attract readers—and to do this, they all need one thing: attention-grabbing images. Satisfying these savvy and demanding fashion-photography clients requires a photographer with both a strong command of lighting and a dash of ingenuity. In this book, veteran fashion shooter Billy Pegram (whose past clients include Fila, Swatch, Pussycat Dolls, and Tony Hawk) shows you how to attain that goal with cutting-edge techniques that showcase flawless skin, accentuate stunning figures, and highlight gorgeous products. Through careful control of the light, whether in the studio or on location, you’ll learn how to manage every nuance of the model’s appearance, drawing attention to his or her standout qualities and minimizing any problem areas. Short, to-the-point lessons with ample lighting diagrams and image sequences make learning easy. Armed with these techniques, you’ll be ready to approach fashion shoots (or fashion-inspired portrait sessions) with confidence—and deliver memorable images to your clients.
Emphasizing how to work with natural light rather than using supplementary lighting to create an artificial environment, photographers can use these simple techniques to mold existing light into the desired quality and shape. All situations are discussed, including overcast and sunny days, backlighting and flare, window light, daylight studios, natural reflectors, and studio lighting at home, offering a plethora of ideas for finding, diffusing, and creating light. As photographers learn the advantages of shooting with available light—no set up, more spontaneity, more time to concentrate on the subject, and the ability to capture preexisting relationships—they not only become better photographers but gain confidence and an increased awareness of their artistic medium.
One volume in the series devoted to physical science. These volumes are devoted to branches of physics related to industrial arts. This particular volume has the spine replaced by the spine belonging to the volume in this series referred to as 'Electricity, magnetism, acoustics.' The work deals with mechanics.
An authoritative introduction to the science and engineering of bioinspired materials Bioinspired Materials Science and Engineering offers a comprehensive view of the science and engineering of bioinspired materials and includes a discussion of biofabrication approaches and applications of bioinspired materials as they are fed back to nature in the guise of biomaterials. The authors also review some biological compounds and shows how they can be useful in the engineering of bioinspired materials. With contributions from noted experts in the field, this comprehensive resource considers biofabrication, biomacromolecules, and biomaterials. The authors illustrate the bioinspiration process from materials design and conception to application of bioinspired materials. In addition, the text presents the multidisciplinary aspect of the concept, and contains a typical example of how knowledge is acquired from nature, and how in turn this information contributes to biological sciences, with an accent on biomedical applications. This important resource: Offers an introduction to the science and engineering principles for the development of bioinspired materials Includes a summary of recent developments on biotemplated formation of inorganic materials using natural templates Illustrates the fabrication of 3D-tumor invasion models and their potential application in drug assessments Explores electroactive hydrogels based on natural polymers Contains information on turning mechanical properties of protein hydrogels for biomedical applications Written for chemists, biologists, physicists, and engineers, Bioinspired Materials Science and Engineering contains an indispensible resource for an understanding of bioinspired materials science and engineering.
In Portrait Photography: From Snapshots to Great Shots, author and photographer Erik Valind shows you how to get the best shots of your subjects–whether you’re in a studio or outdoors, at a family get-together, or at a formal event. Starting with the fundamentals of portrait photography, including how to select the right camera settings and lenses and how to compose your shots, Erik covers building a rapport with your subject, and offers suggestions for poses that flatter your subject to achieve great shots. He then addresses the problems and opportunities of both natural and indoor light, offering ways to resolve lighting challenges of both, showing when and how to use a flash and how to add and modify light to improve the quality of your images. Finally, he walks through several portrait scenarios, including creating single-person shots such as headshots and environmental shots, and group shots such as family and wedding photos. Follow along with Erik and you will: Learn the basics of capturing great portraits, such as focusing on the eyes, stepping back and zooming in, and turning your subject into the light Evaluate focal length, compression, and working distance to select the best lens for any given shoot Establish trust with your subject and provide helpful direction and feedback so they feel at ease and look their best Address challenges associated with natural light such as shade and direct light–and tame or redirect the light for improved photographs Improve the light with modifiers and other helpful tools such as strobes, umbrellas, and reflectors Go “behind the scenes” and walk through the process of creating great portraits with two chapters of start-to-finish examples Beautifully illustrated with large, vibrant photos, this book teaches you how to take control of your photography to get the portraits you want every time you pick up your camera.
