A digital image, just like the image you see on your computer monitor or television, is made up tiny dots called pixels. The term "resolution", when used to describe a digital camera refers to the detail of the digital image the camera produces, and is usually expressed in terms of "megapixels" or how many million pixels it can record in a single image. The number of pixels a camera captures is called the camera's resolution. Resolution directly affects print size and quality and the amount of space required to store a digital image.
