In one of our favorite Madison County barns there is a beautiful old threshing machine, an implement known more simply and affectionately as a “thresher.” Threshers make easier, more efficient work of the task of separating the grains and seeds of small grain and seed crops from the chafe or straw of the plant at harvest time. The thresher here is somewhere between 75-95 years old and has seen its share of harvest moons. There are so many geometries and scales in this wonderful mechanical contraption that it would be easy to spend the better part of a day just playing with the abstracts and intimate landscapes so much in evidence. What really drew my attention to this particular perspective were the spokes of the iron wheel with their enclosing rim, and their relationship to the side of the thresher with its belts and pulleys and levers set in the beautiful old wooden frame of the machine itself. The years-build-up of dirt and grime merely added to the allure. I knew I did not need the entire wheel to tell the story I saw, so I got down to wheel level and used a little more than a quarter of the full part. As we were in the hallway of the building between the two rows of stalls, the afternoon light coming through the opening created an interesting side-illumination. A focal length of 45mm isolated the intimacy of what I saw in my mind’s-eye. An aperture of f/7.1 was sufficient depth of field, considering where I chose for a focal point; and a shutter speed of 6.0 seconds at ISO 100 gave me an overall medium exposure. Obviously, shutter speed time was a big factor in my aperture decision, but f/11 (@ 16 seconds) would have been about as small an opening as I would have used regardless.
