|They used to make devices for scanning slides into flat bed scanners. It had two mirrors at 45 degree angles and sat on top of the slide and reflected the light back through the slide. it did a horrible job and that's why you don't see them anymore. So technically, yes you can but they look pretty bad. |
A dedicated slide scanner is really the only way to go. Many stores that do photo scanning and digital printing can do slide scanning as well. I would try there.
