Suppose you want to scan part of a photograph to use in a digital collage. The part of the picture you want to scan is 2-inch ? 2-inch on the photograph. You want this scanned piece to appear as 6-inch ? 6-inch in the final collage that will be printed out at 300 ppi. If you scan the picture at a resolution insufficient to print it at a size of 6-inch ? 6-inch at 300 ppi, you will have to scale up the scanned image, which will deteriorate the image quality and make it look pixelated.
