No more noise on your digital pictures!
Digital cameras opened the door to easy and entertaining photography. However, consumer digital cameras also have their drawbacks: they often produce the so-called digital noise. It can be seen as grains that compromise the smoothness of the photo. It is especially annoying on the skin as it makes it uneven. This kind of noise is called luminance noise. There can also be chroma (color) noise which is perceived as random red and blue pixels spoiling the color accuracy of the snap-shot.
Digital noise can be produced by a number of factors: heating of the camera sensor, long exposure shooting, small pixel size (therefore digital compact cameras generate much noisier images than digital SLRs), high ISO settings, etc.
