is it possible?
i put some negative on my flatbed scanner and nothing really came out of it. the colours were still, well, negative. and the details were lacking severely. i,e. in a portrait shot, all i could see and make out were just the outline of the body, no eyes, no ears, no mouth.
i've read that some people were able to do it. my dpi was quite high already. my scanner is hp all in one psc1350.
