The Lens

by Nk Guy

Which lens should I buy for my camera? It's such a simple question, but choosing the right lens or lenses is actually one of the most important photographic decisions you can make. Nothing affects the quality of a photo more than the lens. It's no longer just about the megapixels-it's the glass that makes all the difference! Many first-time buyers of DSLRs don't venture past the basic lens included in the box. While some are reluctant to spend more money, others are confused by all the buzzwords or are overwhelmed by all the choices out there. It's really a shame, because interchangeable lenses give you amazing scope for quality photography. Take in vast sweeping scenes with a wide angle lens. Capture faraway birds with a telephoto lens. Examine the tiniest detail of a flower with a macro lens. Record the perfect portrait with a prime lens. Anything is possible when you choose the right lens for the job! This book isn't a simple catalogue of available lenses. New products are coming out all the time, and comparing specific lenses can be difficult. Instead, author N.K. Guy gives you all the information you need to make smart buying decisions. Optical technology is demystified, arcane terminology is decoded, and practical tips are provided. The Lens will help you build the perfect lens collection to suit your needs-now and in the future.

Mastering Canon EOS Flash Photography

by Nk Guy

Digital cameras and flash technology have revolutionized photography. Originally seen simply as a way of illuminating dark scenes with portable light, flash today is used for a host of creative functions, including supplementing daylight and designing complex scenes lit by multiple light sources. Digital cameras with their preview screens make it easy to get instant feedback. But flash photography can still be a difficult artistic and technical challenge. It's simple to get that harsh deer-in-the-headlights look from built-in automatic flash, yet creating natural-looking images is not as straightforward. Manuals are terse and the terminology is confusing. This is where Mastering Canon EOS Flash Photography comes in. This is the authoritative book on the subject, guiding you through Canon's Speedlite system, from off-camera portable flash to professional studio lighting. It covers the fundamentals of flash metering technology, discusses key lighting concepts, and documents a wide range of Canon and third-party equipment. Universal flash accessories, studio gear, and radio triggers are all thoroughly covered. The book is lavishly illustrated with diagrams that demonstrate important functions and lighting arrangements, and inspiring photos that show sophisticated flash techniques. Though tailored for users of Canon EOS cameras, owners of other camera systems will find much valuable information as well. So, whether you're just getting started with flash, whether you've picked up the bug for off-camera lighting from such popular websites as Strobist.com, or whether you're making the leap into advanced studio work, Mastering Canon EOS Flash Photography will be your in-depth resource. Includes a foreword by David Hobby, noted photojournalist and founder of Strobist.com.
