Task 4 How to Reduce Noise

A noisy image has tiny nondetail artifacts that are evenly distributed throughout the image. Noise typically falls into two categories: grain and digital noise. Film scanners often record the actual grains that make up the image, usually in areas of little detail and smooth tone. Digital noise is introduced either by the digital camera during the image-capture process or from post-capture processing and compressing. Photoshop CS2 is now well-equipped to handle all these problems.
