Amber Estes Thieneman confesses right up front that her 15-inch square photographs are manipulated. So much the better for us, for it lets the viewer be involved. They may be based on nature but that’s not where they stay. I’m a fan of art deco, an art movement that celebrates metal and machinery, and I see a little deco in some of the images. “One of my favorite parts of this series is hearing/reading all the different perceptions people have of the images,” she says. “That interaction really brings them to life. Participation requires … the viewer to record [a] perception of the image. Each piece becomes an ongoing conversation.” The exhibition, part of the Louisville Photo Biennial 2015, has been extended through mid-November.
