Usually the scanner has a setting to convert negatives. That will give the best results.
Other possibilties are
- to use an Automator workflow with Quartz Filters (see my User Tip here: Using Quartz Filters with Aperture)
- or use the "Curves" adjustment: set the RGB channel to the mirrored diagonal line. That will map black to white and white to black.
