On my flatbed, yes.  Usually at 150 dpi.  But  now with the FS2710
obviously I'm only doing slides and negs, which is what brought up all
these questions.  

I guess I'm missing the point here.  If I were to scan even a 4x6
print at 72 dpi, and then want to display it anything larger than
288x432 pixels, wouldn't interpolation be necessary?  Even more with a
slide or a negative?
