That's a matter of opinion, I believe. We all know what a vignet is - or do we? Well, a vignet was originally a small drawing in a book right beside the witten words. A vignet was often made in such a manner that appears to be "fading away" torwards the edges - in order to make the drawing look less alien on the page. Light fall off can cause dark corners, due to lens "errors" or caused by a too small lens hood or similar - in a camera making positives. When making a paper copy/enlargement from a negative (i.e. Black and White) light fall off in the enlarger or in the neg will result in too bright corners - or vignetting. The print will look like a vignet in a book. Light fall off is just annother word for vignetting. I guess light fall off is for positives, vigetting for prints. But it is in fact the same thing: http://194.100.88.243/petteri/pont/How_to/ha_Testing_lenses/a_How_to_test_a_ lens.html?page=10

Vignetting happens when something obstructs the light entering the lens, such as a lens hood that's too small.
