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 ? -- Met vriendelijke groeten, Ernst Try: http://tech.groups.yahoo.com/group/Wide_Inkjet_Printers/ | Dinkla Grafische Techniek | | www.pigment-print.com | | ( unvollendet ) |
