Back when I was trying to learn how to print silver you had to have a cold light head on your enlarger, use Tri-X and HC 110 because that's what Ansel was using. I had a chance to look at and hold in my grubby little hand Brett Weston's Tide Pool, 1981, most wonderful print I have ever seen. I figured it was an 8x10 contact because of the wonderful detail and metallic look to it. Found out it was an enlargement from a medium format neg. He was using a lot of Agfapan at that time and I believe in Rodinal and printed with a point light source. It had what he refered to as "Luminisous"(sp). Sorry if I got off the subject.
