Digitise your 35mm slides
With the rise of do-it-all printer/scanner/toaster/hoovers, you don’t often see separate scanners these days. Something you can’t usually do with those you find on multi-function devices, however, is scan 35mm slides. This requires three special features: a way of getting the slides in accurately and efficiently; the ability to shine light through them (known in the trade as ‘transmissive’ rather than ‘reflective’ scanning); and a very high resolution, because you’re going to want to view and print the resulting digital images much bigger than the postagestamp originals.
