To scan photographs effectively, feed them through a scanner that either has automated resolution and color settings, or edit the resolution and color options to best suit individual needs. The specific editing options vary depending on the scanner. When scanning, ensure the photos and environment are dust free.
Scanning is a time-consuming process, and the more time spent on the process, the higher the quality of the resulting scan. If using a flatbed scanner, one way to speed up the process without harming quality is to scan multiple photos at once by laying them side by side on the flatbed.
