Hi Rodrigo,

This is not my own experience, but what I gathered from searching lots 
of internet sites.

Although it is one of my main goals to preserve the original 
photographic grain throughout the whole process, the very hard light 
source, which LEDs are, as used in the Nikon and in the new Minolta 5400 
II, gives a very harsh grain picture and increases dramatically the 
visibility of dust and scratches. Since you can't use ICE with B&W, you 
are in for a very time consuming clean-up. The soft light of the Minolta 
Multi Pro and the old 5400 gives you as much resolution, but without the 
mentioned disadvantages. The resulting softness of the grain can easily 
be corrected with some carefully adjusted acquisition-sharpening in PS.

(The difference is pretty much like the one between an enlarger with 
diffuse light compared to one with a point-light-source, i.e. much 
harsher than a condenser.)

I guess that it would be most interesting to combine an LED scanner like 
the Nikon 9000 with the ScanHancer diffusor, but there seem to be 
technical difficulties preventing this.

PS: As an ooold Nikon user (I still use my F2) I've nothing against this 
brand, and the 9000 is an excellent scanner for color, especially 
Kodachromes.
