Arnie has a bunch of slides that he wants to digitize. Is there something that will take a carousel tray and one by one feed the slide and scan it? Leo says that would be an interesting product, for sure. Leo says he can do that, but taking them to a service like ScanCafe is a better option. Not only is his time worth something, but they'll take the time to clean them up and remove dust. If it's an issue of cost, remember that he'd be buying an apparatus and spending the time. In the end, he's probably paying just as much.
Leslie has a bunch of slides and negatives and wants to scan them all into her computer. She's looking at a pair of scanners by Epson and Canon that can do it. Leo says that it will take a very long time to do that. If she wants to take the time to do it, then she can. But why not have a service do it instead? Her time is worth something and Leo advises a service like Scan Cafe. They would send her a box, she'll stuff it and ship it to them. And it's cheap at $0.22 an image.
