How many photos can I store on a digital storage card?

Digital camera resolution is measured in Megapixels. One Megapixel is made of one million pixels/dots. The more Megapixels per square inch - the higher the resolution, and the better the quality of the photograph. A photograph, whether viewed on the screen or printed, is composed of tiny dots (also called pixels). The more of these dots that can fit in a one inch space, the tinier the dots resulting in a sharper the image. Use the chart below to find what size photo print and quality you can get from your digital camera.
