Thanks for the suggestions, max.

I tried reversing black and white levels in Preview, it doesn't work.

My scanner is a Brother MFP, the scanning software is minimal and lacks a "negative" setting or any image inversion.

I've also tried scanning via Mac OS X's Image Capture and that doesn't have image inversion either. iPhoto also lacks that feature.

I downloaded a trial version of PhotoEdit (Mien Software) but it says "out of memory or corrupt file" when trying to open the scanner file which is about 36MB at 600dpi. I guess I can keep reducing the resolution to get a file that it will open, but a 35mm neg scanned at 100dpi isn't going to be so useful.
