Eight small bridges in winter

When riding my bicycle around town, I often cross little bridges over creeks and other minor waterways that might make interesting photographs. I thought of them when trying to come up with a project recently. It occurred to me that in winter, there might be more options for placing the camera since the ice might make getting to the middle of the stream possible. I was wrong about that and suffered a cold wet foot in learning that lesson. A bit unusual for me was using that most common photographic accessory, an automobile, in order to get to them. It also provided a warm and private place to swap the fronts of the 6x9 Variable Cuboid in the changing bag.

The Sawyer Creek Trail over Sawyer Creek.


The trail connecting Ruschfield Drive and Newport Avenue through Rothschild Park over Sawyer Creek.

Pratt Trail over the lagoon in Menomonee Park.

The driveway to the Oshkosh Country Club over Weyerhorst Creek.


The Riverwalk Trail over a small inlet off the Fox River.


The former railroad trestle on the Wiowash Trail over Dagget’s Creek.


All with the 6x9 Variable Cuboid on Tmax 100 semi-stand developed in Rodinal 1:100

The first four and the last with the 55mm front, .3mm hand drilled pinhole.

The fifth and sixth with the 135mm front, .43mm hand drilled pinhole.

The seventh with the 30mm front, .2mm Gilder Electron Microscope Aperture.

  2. Also, just wondering...what do you think the limitations are on how long you make the Variable Cuboid? Could you go as high as 400mm? 600mm?

  3. The limitations are on the size of the pinhole which limits the size of any detail and the “optimal” pinhole size which minimizes diffraction, which gets bigger the longer the camera is. You could go longer, but the images would get more and more soft. I definitely notice the difference between the shorter fronts and the 200mm. Also the f ratio is going to get pretty high so exposures can get pretty extreme. Jeff McConnell made a 600mm camera 6x7cm camera with a huge pinhole so he could hand hold it for street photography, but I don’t think he was really concerned with sharpness.
