Maximum resolution is one of the most important ratings of a digital camera.
Digital images are made up of dots called pixels. The resolution of a digital camera refers to the sharpness of its pictures and is measured by how many pixels make up a photo, usually measured in the horizontal by vertical resolution. The higher the resolution, the sharper the picture. At the same time it will also mean the more memory that will be required to store an image, both in the camera and on your computer. A camera's memory size will determine how many images you can store.
