Whether noise reduction will be useful depends a lot on the size of the problem and how you want the grain, if any, to appear in the image. With very grainy film, film that'd have a very visible grain pattern in an 8x10" print from 35mm, I found that the Nikon scanner lost detail because of the exacerbation of grain compared to my Canon 9950F consumer flatbed. Software noise reduction could get rid of the grain (and a bunch of detail), but for those images grain was an important part of the final look. Trying to minimize grain of Nikon scan, i.e. making it less noticeable but not gone, led to a nasty smearing of the grain. In these cases, my Canon flatbed gave significantly better results than that Nikon film scanner. I was going to investigate wet-mounting and using diffusion with my Nikon, but I ended up getting a Screen Cezanne, and so I sold my Nikon. [Non-text portions of this message have been removed]
