When you're looking to scan slides and negatives, you can either use Epson devices or standalone dedicated slide/film scanners, which are specially created for this purpose. A good flatbed scanner is able to scan many types of documents, photos, negatives and slides. It has to include the ability to do transparencies too. All-in-ones usually are not built for this. You should choose the highest resolution for slides. If you're a beginner in scanning, it will take a while to get nice results and make photo books, scan and email images that you can send your family members.
