General

Digital noise in photos taken with digital cameras is random pixels scattered all over the photo. It is a similar effect as “grain” in film photography and it degrades the photo quality.

Digital noise usually occurs when you take low light photos (such as night photos or indoor dark scenes) or you use very slow shutter speeds or very high sensitivity modes.

When taking pictures with a digital camera an electronic sensor (also known as a CCD) built from many tiny pixels is used to measure the light for each pixel. The result is a matrix of pixels that represent the photo.

As with any other electronic sensor the CCD is not perfect and includes some noise (also know as white noise to hint on its randomness attribute). In most lighting the light is significantly stronger than the noise. However in extreme scenes where the light is very low or when a high amplification is needed noise levels can become significant and result in pixels in the photos that include more noise data than real photo light data. Those pixels usually appear as random dots or stains on the photo (for example white dots scattered randomly on the photo).

Digital photography strips the pain out of photography in several ways: No film means no mess and less expense. No lenses equals no clutter, and once you get used to using a digital camera, digital photography can even help you take better photos. . Took a photograph you didn’t like? A digital camera lets you review the shot on an LCD screen on the back of the camera right after you snapped it, and delete it.

Are you looking for a fun little camera to take pictures of family celebrations and get togethers? Or, are you more interested in developing your photography skills and becoming proficient at photo shooting and editing?
