Ever wonder how you can convert a written document into a digital image? Or, how about converting those old photo album pictures into digital images? Do you have oodles of 35mm slides or negatives that you’d like to convert to digital images? Well, you need a scanner! In general, scanners can connect directly to your computer or your network. Once installed, you can easily convert documents, photos, or slides into digital images with your scanner. In the past, professional designers and photographers often took old photos, converted them to a digital format, and even touched them up so they look good as new. Fortunately, scanner technology now allows even basic users to do the same.
Nowadays, scanners can be purchased as stand-alone machines, or you can buy a so-called “all-in-one” that has a scanner included in it. Most scanners can be categorized by how much you’ll use them and the amount of resolution that images from the scanner will be. Resolution is simply the sharpness of the image after it is scanned. For example, the higher the resolution on a scanner, which is often listed as something like “6400 x 9600 dpi resolution,” the crisper the image or document that you scanned will appear on paper or on-screen. (By the way, dpi means dots per inch.) As you might guess, the higher the resolution that a scanner delivers, along with its potential workload capacity, the higher the price of the scanner.
