Tiny Cards Hold Digital Memory

digital-storage/index.html">camera-storage/index.html">Digital memory storage is done with cards -- removable cards often no bigger than a postage stamp. These cards allow photographers to plug the cards into their cameras, fill them with photos, and then remove them to download the photos into a card reader. There are three main types of digital meory cards for cameras: compact flash (also known as compactflash), secure digital (SD), and Memory Stick (also Memory Stick Pro Duo). Compact flash cards and SD cards have become more powerful and less expensive. Sony Memory Stick and Memory Stick Pro Duo cards are just as fast, but less desirable because they only work in Sony and a limited number of other cameras.
