The Complete Guide to Sony's Alpha 100 Digital SLR Camera
Gary L. Friedman is a professional photographer who has traveled the world with his Minolta (and now, Sony) cameras.  He runs the stock image website www.FriedmanArchives.com, and travels the world giving seminars on digital photography aimed primarily at beginners who wish to learn the basics and improve their creative photography.   Before graduating to photography he was a rocket scientist for NASA's Jet Propulsion Laboratory, where he patented the image authentication system now used in high-end digital cameras.  He has been published in books, newspapers and magazines worldwide, and was listed in the Guinness Book of World Records while in college (go ahead and search the FriedmanArchives.com website if you want to find out what he did to get included).   Despite his mastery of the technical background, Mr. Friedman has an approachable and easy-going teaching style that makes his books a pleasure to read.
