This exhibit for Callahan is at the Art Institute for those in /near Chicago. Hurry, it is only there for one more week. I just saw it today; I always liked Callahan in books, but seeing the originals of so many famous shots is something else. There are even the negatives of several famous Callahan shots - Trees - Lake Shore Drive, Elenore - Lake Michigan, and others; looking at the negatives (they are displayed on light boxes) you can see how Callahan chose to print them into their final famous versions most of the time he went very contrasty , and eliminated the detail in the neg. ALso shows how he "defied" Ansel and printed something very contrasty (I think it was "Weeds in snow.) Anyway, I'm not doing justice to the exhibit, or HC. If you like Callahan, (or even if you don't - this show may change yer mind) get down there before Sept. 24.
