Electronic Flash Strobe

Spectacular photos begin with your Sony Alpha and this book. With its Alpha A300 and A350 cameras, Sony has blurred the distinction between introductory and advanced dSLRs. With the expert advice in this book, you’ll learn to use every menu and control perfectly and gain insight into setting up and capturing shots that will amaze you. Reach beyond the automatic settings and take control of exposure, shutter speed, white balance, and every creative element that makes photography an art. Part I explores using your Sony Alpha A300 or A350 straight out of the box. Starting with an in depth look at the Sony Quick AF Live View System, this part of the book also explores all the external controls, explaining the purpose and function of each button, dial, and switch. Understanding your camera’s menu system is crucial to getting great results with the A300 or the A350, and of course the book will also teach you how to maneuver through all of your camera’s menus. You’ll not only learn how to adjust each setting, but when and why you should make each adjustment. Chapter 3 gives a thorough explanation of basic photography fundamentals, without overwhelming jargon and technical terms. If you are a new photographer you will gain an appreciation of aperture, shutter speed, exposure, ISO and white balance. If you are an experienced photographer you’ll find helpful tips and tricks for adjusting each of these key settings. Interchangeable lenses are one of a dSLR's major strengths, and that is true of both the A300 and A350. With so many lens options, choosing auxiliary lenses for the A300 series can become overwhelming. Chapter 4 helps you eliminate the mystery about which lenses to buy and gives you a full explanation of what to look for when evaluating a new lens. With information on wide-angle, normal, telephoto, and macro lenses, this chapter discusses the full Sony lens lineup and goes on to demystify the option of using Minolta lenses on the Sony Alpha. Understanding light and light modifiers, such as diffusers and reflectors, is absolutely essential to getting great results from a dSLR. In chapter 5, you'll find a complete discussion of lighting basics, including the differences between continuous lighting and electronic flash. The full array of light modifiers is outlined, and the chapter goes on to explain the strengths and weaknesses of the proprietary Sony/Minolta hot shoe design. Naturally, there is also a discussion of which flash units work with the A300 series. Chapter 6 consists of a series of exercises designed to enhance your skills when shooting in a wide variety of photographic situations, including everything from macro photography and black and white to high dynamic range, portrait, and travel photography. Each topic is accompanied by numerous full color examples. DSLR photography entails far more than just the camera and lens. Once you fill your memory card with great images, you will need to download, catalog, store and edit those images. Chapter 7 takes you through a quick, but informative tour of the software and hardware options available to simplify your digital workflow. You will be exposed to the differences between RAW and JPEG images and you'll receive a thorough overview of your RAW processing options. You also learn about sharpening and noise reduction software, as well as the best editing applications.

High Speed Pulse Technology, Volume III: Capacitor Discharge Engineering covers the production and practical application of capacitor dischargers for the generation and utilization of high speed pulsed of energy in different forms. This nine-chapter volume discusses the principles of electric current, voltage, X-rays, gamma rays, heat, beams of electrons, neutrons and ions, magnetic fields, sound, and shock waves in gases and liquids. Considerable chapters consider the applications of capacitor discharges, such as impulse hardening of steel, ultrapulse welding of precision parts, X-ray flash technology, ultrafast image converters, exploding wire shutters and light sources, electromagnetic shutters, flash photolysis, and spark tracing in aerodynamic and automotive research. The remaining chapters explore other practical aspects, including high energy electromagnetic pulse generation, plasma physics, magnet charging, magnetically driven gas and particle accelerators, acoustic echo techniques for remote atmospheric sensing, sonar, and shock waves in high pressure physics and metal forming. This book will prove useful to physicists, electrical and other engineering fields, teachers, and students who are interested in capacitor dischargers.

High Speed Pulse Technology, Volume IV: Sparks and Laser Pulses covers the production and practical aspects of sparks and laser pulses for the generation and utilization of high speed pulsed of energy in different forms. This volume consists of seven chapters and begins with reviews of the classification of photographic methods of high-speed analysis, specifically the motion analysis of rapid events by white light pulses. The next chapters examine the sources of white pulse light and nanosecond radiation. The remaining chapters discuss the applications of the technology in photography, photolysis, laser pumping, and visualization of flows, cracks, and particles. This book will prove useful to physicists, electrical and other engineering fields, teachers, and students who are interested in sparks and laser pulses.

The opportunities that digital technology presents are almost limitless, but so are the problems that can arise when trying to retrofit a film-based photography business to the new digital marketplace. This guidebook explores digital imaging technology with some of the world's leading wedding, portrait, and commercial photographers, drawing on the experiences of professionals for practical advice for photographers who are still struggling to perfect their digital work flow. Topics include the selection and purchase of the right equipment, choosing the right business model, and tips on innovations in color management and retouching. Step-by-step instructional images and screen shots are included throughout, allowing for a concrete grasp of the detailed processes and techniques.

From a master of professional photography, a book that explores the exciting possibilities of artificial light. This guide to on- and off-camera flash picks up where Peterson's previous title, Understanding Exposure, left off--helping free photographers from the limitations of auto to get the images they want when natural light isn't enough. For the many amateur photographers afraid to venture past natural lighting, here is the book that will finally help them master artificial light. In his trademark easy-to-understand style, Bryan Peterson explains not only how flash works, but how to go beyond TTL automatic flash exposure to master manual flash, allowing readers to control the quality, shape and direction of light for a perfect exposure, every time.
