I'm a very lucky man, I was able to travel to Tuscon Arizona this past week and spend a two days at the Center for Creative Photography at the University of Arizona. The occasion was a symposium on the photographer Harry Callahan.
It's not too much to say that the experience has changed me almost as much as the time Callahan got to spend time with Ansel Adams when he visited the Minature Camera Club at Chrysler Corporation in the early 40's.
By all means get a copy of Britt Salvesen's book, Harry Callahan; The Photographer at Work. In my opinion it should be required reading for every beginning photography student and most of the "advanced" ones as well.
David Travis presented the most compelling talk about Callahan and his work and his work ethic. Interesetingly, former Callahan students like Emmit Gowin and Jim Dow spoke in the most reverential terms about the man who clearly had tremendous influence on them.
The bottom line, you have to do the work and there's really nothing more to say.
Callahan said he was pleased if he got 5 or 6 good pictures a year.
