About noise and noise reduction

Image noise looks like random black, white, or colored pixels in an area of a photo where there should be solid color, such as a dark

night sky. In digital photography, noise is typically more visible in the dark areas of a photo.

There are many causes of image noise. You will increase image noise if you use a high ISO setting (such as ISO 800) to capture a

photo, or if you extend the exposure time. (You would typically use a high ISO setting and extend exposure time to take a photo in

low light.) However, image noise can be caused by dead or stuck pixels in a digital camera's image sensor. Similarly, dust on a

camera lens or scanner bed can cause noise by blocking or reflecting light.

Images generally have two types of noise: luminance and color. Luminance noise is random variations of brightness, and

particularly in gray areas, may appear spotted when there should be a solid color in the area of the image.
