Thin B&W negatives do not scan well on the Nikon 8000 with wet mounting 
in my experience. While they give an acceptable scan on the Epson V700 
so I usually set 50-75% of the ISO value of the film, overexpose and 
process accordingly for a denser but lower contrast negative. I'm using 
a not so fancy B&W development in a Jobo Auto processor with a Rodinal 
dilution. Consistent but not optimal. Scan with Vuescan and one of the 
B&W development profiles that give the right histogram, 64 bit Tiff 
output. Tried a RAW route but do not see much gain that way.

Tyler,

Does the Bruce Lindbloom application work well with any B&W (aliased) 
grain ?
