Now fully updated for the digital photographer, an authoritative and contemporary guide to Ansel Adams's Zone System, presented by one of the true masters of this influential photographic technique.

The Zone System is not just a relic of the past! This book addresses how the Zone System is applied to digital shooters in the world today.

* A primer on basic photography with examples from professionals and how they achieved their results * A unique discussion on the Zone System in color and digital photography * Two Zone System testing methods * Ten detailed and accurate development time charts for the most popular films A newly revised version of a photography classic, Practical Zone System, Second Edition makes this important method available to beginning, large format, 35mm and professional photographers. In addition to demonstrating what the Zone System is and how it works, Practical Zone System, Second Edition shows how to assess prints and negatices for contrast, recognize the zones both on the print and in real life, previsualize photographs and expose accordingly, and test equipment and chemicals for reliable, consistent results. There are numerous photographs and easy-to-read diagrams, as well as a glossary of zone system terminology.

In this fifth edition of The Practical Zone System, Chris Johnson updates his classic manual on Ansel Adams's landmark technique for the digital age. Whether you are a beginning, large-format, or professional photographer; whether you work with digital or film; and whether you shoot in black and white or color, the simple visual language called Previsualization will help you to control contrast in order to create beautiful photographs. Entirely new to this edition is a chapter applying Zone System concepts to studio photography. Using Bill Brant's "Nude, Campden Hill London, 1949, May" (cover image) as an inspiration, Johnson demonstrates how the Zone System, traditionally considered to be a methodology limited to the uses of films and developers, is actually a universal visual and conceptual language that dramatically simplifies the problem of creating and rendering complex studio lighting setups. *Written in plain English - Chris has taught the Zone System to countless budding photographers and knows how to explain this complex topic in non-technical terms *The only resource available with comprehensive information on Zone techniques specifically for studio shooting *Information is applicable to film and digital shooters.

Geared toward the HVAC professional, Practical Controls: A Guide to Mechanical Systems provides a solid foundation and well-rounded understanding of the role of controls in mechanical systems design and installation. This book takes a concise look at HVAC controls and controls methods - including electrical, electronic, and microprocessor-based controls and control systems. Using "real world" examples, it explores how various mechanical systems installed in today's facilities are best controlled. The text is a practical resource to controls contracting, providing basic rules, equipment guidelines, rules of thumb, pros and cons, and do's and don'ts.

The Practical Zone System: for Film and Digital Photography 4th edition is an updated version of what has become the classic book on the technique developed by Ansel Adams in the 1940's. The zone system was designed to provide photographers with a precise and intuitive way to control the dynamic range of their negatives to produce printable results regardless of the contrast of the subjects they are shooting. What Chris Johnson has done in this new edition is completely update his approach to teaching the zone system with new film/developer testing data and new illustrations and examples. Most importantly, he has added an extensive new chapter that provides a detailed explanation for how the zone system's conceptual approach and terminology can help digital photographers achieve the highest possible quality from digital image processes. The emphasis is on subjects that include: optimizing digital camera exposure, color management and a fine printing workflow. Other important updates include: * Workflow for fine digital printing * Contemporary images * Updated film/developer test data * New film/developer tests * Updated Appendixes.

Douglas uncovers the underlying reasons for lack of consistency and helps traders overcome the ingrained mental habits that cost them money. He takes on the myths of the market and exposes them one by one teaching traders to look beyond random outcomes, to understand the true realities of risk, and to be comfortable with the "probabilities" of market movement that governs all market speculation.

From the Director and Associate Director of the VA's National Center for Post-Traumatic Stress Disorder: a highly practical, user-friendly guide that answering all conceivable questions about returning from war--for veterans and families Two experts from the VA National Center for PTSD provide an essential resource for service members, their spouses, families, and communities, sharing what troops really experience during deployment and back home. Pinpointing the most common after-effects of war and offering strategies for troop reintegration to daily life, Drs. Friedman and Slone cover the myths and realities of homecoming; reconnecting with spouse and family; anger and adrenaline; guilt and moral dilemmas; and PTSD and other mental-health concerns. With a wealth of community and government resources, tips, and suggestions, After the War Zone is a practical guide to helping troops and their families prevent war zone stresses from having a lasting negative impact.

The essential introduction to the principles and applications of feedback systems—now fully revised and expanded This textbook covers the mathematics needed to model, analyze, and design feedback systems. Now more user-friendly than ever, this revised and expanded edition of Feedback Systems is a one-volume resource for students and researchers in mathematics and engineering. It has applications across a range of disciplines that utilize feedback in physical, biological, information, and economic systems. Karl Åström and Richard Murray use techniques from physics, computer science, and operations research to introduce control-oriented modeling. They begin with state space tools for analysis and design, including stability of solutions, Lyapunov functions, reachability, state feedback observability, and estimators. The matrix exponential plays a central role in the analysis of linear control systems, allowing a concise development of many of the key concepts for this class of models. Åström and Murray then develop and explain tools in the frequency domain, including transfer functions, Nyquist analysis, PID control, frequency domain design, and robustness. Features a new chapter on design principles and tools, illustrating the types of problems that can be solved using feedback Includes a new chapter on fundamental limits and new material on the Routh-Hurwitz criterion and root locus plots Provides exercises at the end of every chapter Comes with an electronic solutions manual An ideal textbook for undergraduate and graduate students Indispensable for researchers seeking a self-contained resource on control theory
