About the Author David D. Busch has been demystifying computers, digital imaging, and photography since the early 1980s with nearly 70 books and 2500 magazine articles for dozens of leading computer and photographic magazines, including Macworld, Computer Shopper, The Rangefinder, and The Professional Photographer. Digital Photography For Dummies Quick Reference is his second book in the For Dummies series. Before he was seduced by the dark side of technology in 1977, Busch operated his own photo studio and had his work published on the covers of magazines and in both print and television advertising. He says his chief motivation in writing books these days is to create venues for publishing photos of his wife and four children.
