TestFreaks posted a review on the Plustek OpticFilm 7600i SE Film and Slide Scanner

Today we are reviewing the Plustek OpticFilm 7600i SE scanner. It is a negative film and slide scanner. For you completely digital people out there I'll explain: Film is an analog way of capturing an image. Instead of a digital sensor collecting photons there is a light sensitive emulsion onto which the light is shone. Then, through a chemical process, the film is developed to create the final image. From this image we can make prints. To get the image into the computer it has to be scanned. That's what we have film scanners for.
