If you need a methods of transferring your old negatives into a digital format Claus Thiim has a great solution using a DSLR camera and a few paper toilet tubes.
Thiim has used a 90mm manual focus lens, an extension tube that moves the lens forward and allows closer macro focusing. Together with a couple of paper toilet tubes taped to a filter with the glass removed and a 35mm slide mount to hold the negatives.
The method provides a huge speed advantage over even the faster negative scanners currently available. Allowing you to slide the negatives through the holder and click away transforming them into digital images. All for a fantastic low price as well, what more could you ask.
