Are you sure you are setting the black point correctly? Virtually all 
scanners degrade to green/blue mush at the dark end, but the more 
competent ones do so at luminance values which are below those found in 
the shadows. If so, you will be able to clip the black point to lose the 
noise, yet not retain all or most of the image shadow detail.
