If you get the TRIO network, keep an eye out for the documentary "The Meaning of Photographs." It's terrific and in current "rotation" on TRIO (and my TiVo, heh).

Don't get TRIO, but will say Mr. Adams work is Very Good, and I think it would be worth watching..

Darn, not having cable/dish..

Oh, well guess that just means more darkroom time.
