If it's showing up in the shadows of a positive (Velvia slide), it *is* noise and not grain. Noise shows up in areas of extreme density, the shadow areas of slides, and the highlight areas of negatives.
All scanners do this to a certain extent, but the high end ones to a lesser degree. Unfortunately the price of those higher end models probably *start* at the $13K range, and go up from there (way up)! I know, I've been 'shopping' for an affordable one recently. The most cost effective solution I have come up with so far, seems to be a refurbished Howtek drum scanner at around $7K, but I'm not that sure about how good the noise reduction would be. (BTW: one of the reasons that I've been looking at these is the need to scan 4x5 as well.)
