We’re back on the Calumet River returning to Lake Michigan, and the lighting and placement of all of these structures — lift bridges and grain elevators — really caught my eye. The harsh lighting from a difficult angle made much of the trip difficult to capture well, but here these structures were out in the open and well-lit to show off all the detail. I’ve talked a bit about how industrial engineering fascinates me, and this photo of two of my favorite subjects in that category shows off why.
