This a cut and paste from that other website but it's a good one;

I just got the first weekend of a two weekend seminar at the ICP in NYC done. It is in advanced printing. At the end of the first day, the teacher, who is a Magnum printer and well known printer around NYC showed off some "one-off" prints that he ahd done for some famous photographers. He brought out full fram 16x20 prints that were made from 35mm and they were incredible. I ever knew that 35mm could be enlarged to this extent. They were almost all Tri-X at 320 in Microdol, and they were beatiful and sharp. I know that most think Microdol is soft, but I have no doubts that it can produce great prints.
