ImageMagick Negfix8

How on earth do I get this to work?!! I can open the program and bring a linear scan from Vuescan in but then what? What's the idiots guide? I cannot understand the on-line help.

This looks like a quick howto guide for this script. It requires that you are somewhat familiar with the command line, it's a command line tool after all. There exist GUI based negative conversions programs, but they cost money and run only under a limited subset of operating systems.

Thanks for that. It's going to be beyond me. I even had to look up what a Command Line and GUI was LOL. It's a shame because it looks just the ticket.
