Re: filmscanners: Canon 4000 scanner VS Nikon LS4000 >Mikael



Nikon might be approaching the limits of linearity in the LEDs.  They 
also need to be able to have a range of brightness available to them for 
the "analog exposure" they offer.  Since Blue LEDs are (or at least 
were) the least bright, they might be the limiting factor.
