Archiving includes capturing all the detail contained in your film or prints. If you’re unsure about your future needs or simply want to preserve as much detail as possible with your scans, then archiving would be the choice for you. Modern scanning equipment can sometimes capture more detail than a piece of film or print contains, so the highest resolution possible is not always the best choice. Scanning beyond the detail contained in a given image only adds more data without any extra detail. Prints typically contain no more than 600 DPI worth of detail so scanning at higher resolutions is not necessary. However slides and negatives contain much more detail per square inch and thus need to be scanned at much higher resolution than prints. The amount of detail a slide or negative contains varies with film type and film speed.
