Penn, Cartier-Bresson, Weston, Steiglitz, Adams, Avedon, Cunningham, Abbott, Bernhard, Steiglitz, Steichen, Arbus. . . They were the greats; each brought a unique viewpoint. Then are a few who are still living, but have stopped working - Tice, Caponigro. Finally, there are some that are still productive: Salgado, Kenna. But once learning the basics, nothing replaces looking and doing and then learning to look.
Genesis was a great exhibit, but Salgado showed too much and too many images.
Thanks for the heads-up about Penn. While his portraits are unparalleled, I have seen a couple of still-lifes that are to die for.
I would add Avedon's "In The American West" to a list of great projects like Salgado's Workers and Genesis. The prints are monumental.
