That picture with Avedon's markings all over it was published in American Photo about 12 yrs ago. I forget the exact date, but I have it somewhere. They did an awesome article that explained Avedon's lighting, cameras, film and developer, and printing...everything! He shot Tri-X in 8x10 for most of his later work, such as the example you linked to, developed in straight D76 for about 50% more time than Kodak recommends. He did this to exaggerate midtones and used the extreme dodging and burning shown in the example to bring the overdeveloped highlights and too-dark shadows back to normal. He could do this because the prints were extremely large, often over 10 feet tall! You cannot do that kind of print manipulation on an 1x14 or 16x20 print no matter how good a printer you are. I know from trying and I was damned good in the darkroom. With Photoshop and a scanned neg its simple, though time consuming. He had a fulltime printer do his prints.
