I tried the invert function and it is not doing what I want to do.
I want to rescue old color negative 35mm film strips by inverting them to a color positive that I can print
on a color laser printer.
The negatives have an orange cast which inverts to monochrome blue.
Restoring old negatives involves more than just a colour inversion. The
colour balance is likely to be off. I have 400 colour slides to scan and
restore that date back to the last 60s to mid-70's. I know the colour
balance is off as the red has faded over time. I don't yet know about any
changes in brightness and contrast.
One other (non-GIMP) approach to fixing slides that you may be able to adapt
to negatives by adding a colour inversion step can be found at:

I haven't tried it yet but I'm thinking about it. It was mentioned in this
mailing list some time ago.
