If you’re ever in a pinch, and need to scan slides or negatives using household items, this is for you! With just a simple toilet paper roll and a DSLR camera, you can take fairly decent scans of your slides with no high-end equipment necessary. For true archival quality, we always recommend using a dedicated slide scanner.

Onto the front are mounted an old manual focus (90mm) lens, an extension tube (which moves the lens forward and allows closer macro focusing). Then things get creative, with a couple of toilet-paper tubes taped to an old filter with the glass removed, along with a plastic 35mm slide-mount on the end. The mount is opened at the sides to let the film slide through.” Click for the full post.
