Host Mark Bennett looks at the Brownie camera and photographer Alvin Coburn, each arriving on the scene in 1900 following a couple decades of development, and they both persisted until 1966. Funny how that history worked out. Mark Klett has built his own history by, among other projects, tracking down and rephotographing scenes of the American west, including some originally shot by Coburn. Listen in for a historic conversation. Plus macro photography, a focusing rail, and focus stacking.
