In 11 chapters, professional commercial photographer Sholik discusses the best filters for digital photographers working in various conditions and seeking specific effects. The introduction and chapter one discuss digital filter basics and how to choose a camera filter system. The remaining chapters address the following types of filters: color-conversion, light-balancing, and color-compensating; polarizing; graduated; softening; neutral- density and contrast-control; enhancing; special-effects; black and white; infrared; and close-up. Each chapter explains choices of filter for both cameras and computer retouching. Color images and diagrams illustrate the effects of each filter. The appendix reviews concepts for understanding light and the relationship between f-stops and filter choice. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
