Digital images taken in certain illumination and camera setting conditions will present a certain amount of digital noise (in the frame noise appears as annoying red, green and blue blocks). If the amount of digital noise in a picture is too much, it will ruin that particular image.

In order to reduce digital noise from the source, when taking a picture, use the lowest available ISO setting in the camera.
