If you're scanning old film negatives, slides, high-quality prints, or artwork, you'll probably want to go as high as you can to extract all of the available details. Higher DPI settings also result in slower scans. The higher the DPI, the larger the image. If you scan the same document at 600 DPI, it will have a resolution of 5100圆600. As an example, if your scanner has an area of 8.5''x11'' and you scan a document at 200 DPI, the resulting image will have a resolution of 1700x2200.
