filmscanners: Multiple passes

[Ken Durling <kdurling@earthlink.net>]

Someone feel like expounding briefly on the multiple pass technique?
I'm using Vuescan and a FS2710, slides and both color and B&W negs.
What is the purpose and what determines the number of passes you set?
I tried a couple at 2 passes, and saw no noticeable effect, although
I'm not at all sure what I'm looking for.
