A digital path to better pictures

摘要

Digital image processing offers the photographer new opportunities to cerate better pictures. After a scene has been captured in digital form, digital processing can selectively modify protions of the picture. The photographer can divide parts to be retained and those to be changed in many different ways. This is particulary important when combining several photographs. Amateur and commercial photographers will use digital methods differently, but in both cases the most value is derived when the entire work flow, from capture to delivery, is optimized for the new technology. Digital imaging introduces several new issues concerning image quality. However, with proper care, the quality of pictures generated digitally can exceed traditional results.
