Nice hack for duping slides- I started this because I have about 2000 35mm slides and nearly that many color negatives I’d like to convert to digital images, and many of them are 30 years old or more and starting to deteriorate. My first attempt involved purchasing a slide scanner from the-store-that-must-not-be-named, but it took like 3 to 4 minutes to prescan and then scan to file, and then it usually botched the exposure or the color balance. I realized that I didn’t want to spend the rest of my life scanning slides in this manner, so I started thinking about other solutions…[via] Link.
