converting normal maps to bump maps?

i've seen plenty of info and tools for converting bump maps to normal maps, but how about the other way around?

Hi, you can try it with Corel Painter: go to "Effects" and choose "surface textures" than applay bump effects with "Image luminance" and after change the mode color in gray. For that is good Painter from 4 until 8 . If you don't have it you can downloaded with "Hotline " or "frogblast " surching it here: tracker-tracker (on google). ciao...

I won't condone piracy, but fortunately Painter 7 was on the required software list for school, so I already have it. I'll try that out, thanks!
