Yes, I'm using a Nikon LS5000 with an SF-210 batch loader. I'm using the
Silverfast 48bit HDR scan with two exposures. According to the Silverfast
site, it is normal for the raw scan to be very dark but it does contain all
of the information available in the slide. I think where I am messing up
is in the conversion and post-processing. I have no problem at all with
any other film. Just the Kodachromes behave this way. But I have tons of
Kodachromes to scan!
Color negatives scan fine: http://www.pbase.com/tinamanley/image/143476719
