A photographic colour negative doesn't just have the "opposite" colours
to the positive. It also has an orange-ish mask which adjusts the
colours to better suit the response of colour print paper.
So simply reversing the colours with the usual Negative command in an
image processing program will not give good results. You would need to
do further processing.
Black-and-white negs are OK. You may need to adjust the gamma, of
course, or edit the curve if the software allows it.
