Unlike other digital cameras, the digital single-lens reflex (SLR) offers interchangeable lenses, upgrades and add-ons, increased battery capacity, and no annoying shutter lag-advantages offset by their additional bulk and price. Longtime photojournalist Busch, who has authored dozens of photo books, intends this work for serious digital photographers and those needing to make quality photos for business purposes. In it, he explores the best lenses for any situation, inventive exposure techniques, and methods of infrared, time-lapse, and night photography. This is the best book available for digital SLR. For one on general digital-camera work, see the revised edition of Tom Ang's Advanced Digital Photography: Techniques & Tips for Creating Professional Quality Images.
