I don't get it. Why would a person intent on making photographs scan negatives? Sure you could show those negatives as screen-lookers on a computer monitor but you may as well gaze at them on a light box with a lot less trouble. And if you want positive photographs then it's really easy to re-photograph those negatives with paper-backed film, also known as photographic paper. An enlarger makes the process simple and the subsequent develop, fix, wash steps must be very familiar to someone who already processes their own film.
Sometimes I scan negatives in (especially small formats) so that I can make a digital negative for alternative processes, such as carbon transfer, and kallitype.
