Re: [Digital BW] Coating revisited

2002-04-04 by Julian Thomas

Martin, thanks I'll try it. I've been looking at dig prints for so long,
seeing high quality wet prints blew me away. BTW I showed Pablo a large copy
of Mike's tramp printed full width on his 7000, 'hijo de puta' was the
response. I'm always a bit sheepish about showing that print of Mike's
because the scan/print blows my stuff out of the water. Drum scanned big
prints can't be beaten IMO.
