I appreciate the responses from the people who told me how they 
scanned, and I also appreciate the responses from those who 
questioned why I would want to scan a black and white negative as a 
color transparency (for the answer to this question, see the current 
issue of Shutterbug magazine and the article in it on scanning black 
and white negatives for one source). However, interesting as these 
responses were (and I thank the people who took the time to send 
them), they didn't really address the question I asked. If anyone 
knows the answer to the question I asked I'd appreciate hearing from 
you. To the person who asked what scanner and software I use, I use 
the Linoscan 1400 scanner and the Newcolor 5000 software. Thanks 
again.
