You may already have a computer and printer/scanner at home that allows you to scan images at a dpi (dots per inch) of at least 300 and doesn’t have a light reflection when scanning. If you can change the settings, a 600 dpi is preferable for archiving. You can choose higher resolutions but unless you’re going to blow it up to huge proportions it can be overkill. Remember too that the original photo was probably not high definition so even if you scan at an extremely high resolution, when you do blow it up it still won’t be as crisp as the photos we take today.
