"I remember my first one-day class on how to use Photoshop in 1997. During the long drive home I was excited by the possibilities of what I had seen a Photoshop Master accomplish. However, as I began work on my own images I had great difficulty implementing what I had “learned.” Even though I had diligently scribbled notes during the entire class, when faced with the power and complexity of the program, I hardly knew where to begin. Photoshop was speaking a language, indeed it was a language — one that I had not yet learned. Over the years that followed I gradually learned Photoshop’s language. In hindsight, what I really needed was a primer that outlined, step by step, exactly how to optimize my images and why I needed to do it in a particular way — a book that cut no corners or assumed that, as a beginner, I did not need to understand the big picture, complex techniques or why things worked.
I have written Photoshop Astronomy to do just that. It is packed with tutorial examples that are specific to astronomical imaging. Each Photoshop step is explained in great detail. A beginner will see results immediately. But make no mistake; this is not a “Photoshop for Dummies.” I have not avoided complex material or procedures. Quite to the contrary, I have included difficult, extended image-processing tasks along with the simpler ones. Once you see how even the difficult procedures are worked with my step-by-step examples, their “difficulty” vanishes. There are many things within this guide that even seasoned digital imagers will find challenging and useful. I have also included explanations of how and why things work. “Do this” and “Do that” are not sufficient. It is my firm belief that to speak the language of image processing you must understand the meaning of its “words” and their syntax. I have seen this method work during the many seminars I have conducted for amateur astronomers across the United States." -- L. Scott Ireland

Scott’s photographs have been published internationally in many books, textbooks and periodicals, and have appeared in various museum and gallery exhibits. His publication credits include Nature’s Best Magazine, Nature Photographer Magazine, the National Audubon Society Field Guide to Florida, the Peterson Field Guide to the Stars and Planets, Odyssey Magazine, Sky & Telescope Magazine, Introduction to Observing and Photographing the Solar System and Mercury Magazine. Scott’s images of the Soufriere Hills Volcano on Montserrat were selected by University College, London for use in their volcano hazard mitigation literature being distributed to governments and volcanologists throughout the Caribbean. His images of the Mount St. Helens eruptions of October 2004 have been published and archived for scientific use by the Smithsonian’s Global Volcanism Program. Scott was a member of the National Geographic team sent to Arenal Volcano in Costa Rica to film the documentary entitled Volcano Hunters. Two of Scott’s images were among the winners of the prestigious annual Nature’s Best Magazine international photo competition, and will be exhibited at the Smithsonian in late 2005.
About the cover photo: The bright star in the upper middle of this photograph is S Mon. It is surrounded by dark dust and glowing gas. The area below and slightly to the right of S Mon is called the Fox Fur Nebula because of its color and texture. Tony Hallas took this photograph using a 14.5” f/8 RCOS Classical Cassegrain and an SBIG STL-11000 CCD camera mounted on an Astro Physics 1200 GTO mount. The exposure was 180 minutes through AstroDon H-a and RGB filters (LRGB 120:60:60:60). Copyright 2005 by Tony and Daphne Hallas.
