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-the-moment guide to all photographic filtering issues and is beautifully illustrated with Ross Hoddinott's superb digital pictures.
