While the card probably won't be permanently damaged, its contents can be rendered unusable. Sometimes static electricity can do it sometimes a glitch in your computer or in your camera can mess up a card. Though it's rare, a Secure Digital card can be corrupted. The risk, though, is that if something happens to the card, all your images will be lost. The advantage of a high-capacity card is that your shooting won't be interrupted with a card change. You can get a few high-capacity cards or more lower-capacity cards. With the range of capacities available, you can carry storage in several ways. In fact, because the XS's battery is good for 'only' about 500 shots, if you're carrying a couple of high-capacity cards, you'll probably run out of battery before you run out of storage. The camera creates folders on the card and stores files in those folders, each with a different name.īecause cards are so small and because they can pack huge capacities, it's possible to shoot a tremendous number of images with just one or two cards. Your camera treats the card just the way your computer treats your hard drive. Consequently, it's perfectly safe to take out a full card and replace it with another. So, after you turn the camera off, the images remain on the card, even if you remove it. As you've already learned, the XS uses Secure Digital cards (or SDHC cards, a faster, higher-capacity version of SD).įlash memory cards are similar to the RAM that's in your computer but with one important difference: They don't require power to remember what's stored on them. For that, a digital camera employs a memory card of some kind. With a digital camera, the image sensor does the capture, but it doesn't have any capability to store an image. Film is an amazing invention because it's a single material that can both capture an image and store it.
