This tutorial will show you how to "scan" your film using a Digital SLR. The reason for using a digital camera instead of a film scanner is to save money and ensure that your film is safe. A good film scanner is not cheap, so the investment is only worth it if you scan a lot of film. Your other option would to have your film scanned by a lab, but many people are not comfortable sending off film in the mail.
We're the first to admit that this technique won't give the same quality result as a professional scanner. That said, it's a fantastic idea and a great way to easily convert your negatives to digital images at home.
