Digital photography has changed the art of filtering forever--no longer is it just a matter of in-camera technique, but now encompasses a wide range of manipulations in the digital darkroom. In this comprehensive guide for the modern photographer, Ross Hoddinott explains when and how to use traditional hardware filters on your camera; and how to achieve the same effects with software instead, as well as a wealth of other digital filter-effects that were impracticable or impossible on film. This book provides an up-to-themoment guide to all photographic filtering issues and is beautifully illustrated with Ross Hoddinott's superb digital pictures.
