While light is required to make a photograph, light alone is not enough. More often, it is the way the light has been modified and shaped that brings an image to life. In this book, Glenn Rand and Tim Meyer offer a comprehensive approach to the tools and techniques photographers can use to shape the light—creating the style, energy, emotion, and feeling that make a photograph exceptional. Clear text is paired with ample before-and-after images and diagrams to make learning easy. Beginning with the physics of light, the authors show you how to predict light’s interaction with the surface of the subject/object you are photographing. Based on this, you can begin to make informed decisions about what kinds of modifiers will help you achieve the look you want. Using softboxes, umbrellas, masks, gels, reflectors, and more, you’ll learn to precisely control the light’s diffused edge and ratio for precise, flawless results.

This book is a contemporary overview of selected topics in fiber optics. It focuses on the latest research results on light wave manipulation using nonlinear optical fibers, with the aim of capturing some of the most innovative developments on this topic. The book’s scope covers both fundamentals and applications from both theoretical and experimental perspectives, with topics including linear and nonlinear effects, pulse propagation phenomena and pulse shaping, solitons and rogue waves, novel optical fibers, supercontinuum generation, polarization management, optical signal processing, fiber lasers, optical wave turbulence, light propagation in disordered fiber media, and slow and fast light. With contributions from leading-edge scientists in the field of nonlinear photonics and fiber optics, they offer an overview of the latest advances in their own research area. The listing of recent research papers at the end of each chapter is useful for researchers using the book as a reference. As the book addresses fundamental and practical photonics problems, it will also be of interest to, and benefit, broader academic communities, including areas such as nonlinear science, applied mathematics and physics, and optical engineering. It offers the reader a wide and critical overview of the state-of-the-art within this practical – as well as fundamentally important and interesting – area of modern science, providing a useful reference which will encourage further research and advances in the field.

A practical, hands-on guide to lighting for video, this book explores how LEDs are changing the aesthetics of lighting and provides students with an indispensable guide to the everyday techniques required to produce professional-quality lighting in the age of LEDs and wireless control options. The book focuses on first-hand application of technical knowledge, beginning with simple lighting setups and progressing to more complicated scenarios, and features accompanying diagrams, illustrations and case studies to demonstrate their real-world application. Key topics covered include basic three-point lighting, lighting moving actors, set lighting and exposure, instrument selection, bringing style to your lighting, color temperature and the Kelvin scale, exterior lighting, lighting categories and genres, green-screen techniques, money and budgeting, and electricity and electrical distribution. The book also provides guidance on career paths including what a grip does, case studies with photos and diagrams, and an extensive glossary of set terminology to introduce students to the language of filmmaking. A must-have resource for film and media production students taking classes in lighting and/or cinematography.

The production of biological light (ultra-weak photon emission or biophotons) within many types of cells and tissues is characteristic of an alive organism. You will begin a journey of discovery about biophotons in relationship to biological matter and about how such biophotons can be detected utilizing specialized very photon-sensitive technologies. In this book, Roeland Van Wijk provides a unified synthesis that facilitates easy entry into an exciting sub-field of biology. Light in Shaping Life encompasses the history of biophoton research, insight into how biophotons are generated, and into their involvement with life. Also included, is an overview of the potential benefits of such research to a better understanding of health and medicine. There is sequel to Light in Shaping Life available: Biophoton Technology in Energy and Vitality Diagnostics A Multi-disciplinary, Systems biology, and Biotechnology Appraoch Roeland van Wijk, Yu Yan and Eduard van Wijk Meluna, 2017 ISBN 9789081884341

Selective Laser Melting (SLM), also referred to as Laser Powder Bed Fusion (L-PBF), offers significant advantages for the manufacturing of complex, high-quality parts. However, its market share is still small compared to conventional manufacturing technologies. Major drawbacks hindering an industrial ramp-up are low productivity, high part costs and issues with quality and reproducibility. Comprehensive research has been done to overcome these challenges, but little attention has been paid to addressing them by optimizing the laser beam profile. Therefore, the author examines the effect of the laser beam profile on the productivity and process stability through both numerical and experimental investigations. The results show clear advantages an optimized laser beam profile offers.

Small-flash photography has become widely popular because of its portability and affordability, and this book offers insights on mastering the use of small-unit, hot shoe–mounted flashes called flashguns. Demonstrating the various light modifiers, techniques, and setups designed for these small powerhouses of light, the book explores how to achieve creative results from working with a single flashgun, multiple flashguns, and colored filters, as well as making adjustments with the camera’s white-balance settings. The guide lists the tools required for location-portrait photography and discusses different lighting setups—from shooting in direct sunlight to night and low-light photos—for various location-portrait situations, giving photographers the confidence to make lighting decisions to produce professional results.

Combining theory and application, A Practical Guide to Stage Lighting provides a comprehensive analysis of lighting systems along with examples and illustrations of the technical tools and methods used in the industry. An entertaining and educational read, author Steven Louis Shelley draws from his 35+ years of diverse experience to explain how to get the job done along with real-life examples of projects from start to finish. Learn why some techniques are successful while others fail with 'Shelley's Notes' and 'Shelley's Soapbox,' all with a humor that guides you through complex problems and concepts. Highlights include: -Over 100 new topics, including analysis and application of the three categories of collaboration; a detailed examination of production meetings and one-on-one meetings; and meeting checklists with management and the creative team. -Over 50 new illustrations, including Shelley's Periodic Table of Fundamental Lighting Systems; groundplans, sections, and front elevations that illustrate basic system wash configurations for each direction of light. -Analysis, calculation, and step-by-step technical construction of each lighting system in the Hokey light plot. -Explanation of a manufacturer's cut sheet, and how to apply basic formulas to determine the beam size, footcandles, and gel transmission for lighting instruments. -Updated process of pre-programming computer lighting consoles prior to the load-in. -Comprehensive overview of archiving paperwork and softcopy for a production.
